What is the difference between fungi and protists?
· Slime molds are fungus-like protists that live on decaying wood and compost. Fungi are one of the world’s oldest organisms, having first appeared on earth some 1.6 billion years ago. Most scientists consider fungi to be independent organisms, even though they are often extremely closely related to other organisms, such as insects or other fungi.
What are the four types of plant like protists?
Fungi‐Like Protista The Kingdom Protista was established in the 1860s as a place for the slime molds that are plant‐like in forming spores in multinucleate, erect, sporangia and having cellulose in their cell walls, animal‐like in having an amoeboid stage in their life cycle during which they creep about ingesting their food, and fungal‐like in general appearance and habits.
What are four examples of plantlike protists?

Fungus-like protists are molds. Molds are absorptive feeders, found on decaying organic matter. They resemble fungi and reproduce with spores as fungi do.
What are the characteristics of fungus-like protists?
Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores, just like fungi. Fungus-like protists usually do not move, but a few develop movement at some point in their lives.
What are the three fungus-like protists?
Three examples of fungus-like protists are water molds, downy mildews, and slime molds.

their lives as one-celled organisms and part of their lives as many-celled organisms. Although many are called molds, they are not the same as the molds you will read about in the next section of this chapter. Slime molds, water molds, and downy mildews are examples of funguslike protists.
Do fungus like protists reproduce asexually?
There are few similarities between individual members of this Kingdom, as it includes all the eukaryotes that are not animals, plants, or fungi. Most protists are microscopic and unicellular, though a few species are multicellular. Typically, protists reproduce asexually, though some are capable of sexual reproduction.
What characteristics do fungus like protists have select the two answers that are correct?

The three types of fungus-like protists are slime molds, water molds, and downy mildews.
What are the 4 types of animal-like protists?
Animal-like protists are also known as Protozoa. Some are also parasites. The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Are fungi protists?
Protists are unicellular organisms, which cannot be typically observed by the naked eye. They are classified under the kingdom of Protista as eukaryotes, which are not either fungi, plants or animals.
How are fungi like protists similar to fungi?
Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores, just like fungi. Fungus-like protists usually do not move, but a few develop movement at some point in their lives.
What are fungi-like protists called?
Fungi-like protists are called fungi.
What are the three fungus-like protists?

Why are they called fungus-like protists?
Fungus-like protists are a group of single-celled organisms that have the ability to reproduce by budding.
What are the three major categories of protists?
Animal-like protists, plant-like protists, and fungus-like protists are the three major categories among the protists that are characterized by how they get their nourishment. Protozoa are protists that look like animals and eat and digest their food.
How many groups of protists are there?
Animal-like, plant-like, and fungus-like protists may all be divided into three groups. The mode of reproduction, technique of feeding, and motility of an organism are used to classify it into one of three groups.
What are the two structural components of a fungal cell wall?
Glucans and chitin make up the fungal cell wall; although glucans are also present in plants and chitin is found in arthropod exoskeletons, fungi are the only creatures that combine these two structural components in their cell wall. Fungal cell walls lack cellulose, unlike those of plants and oomycetes.
What is slime mold?
Slime molds are slimy clumps of fungus-like protists that develop on rotting materials. They may be found on decaying wood, for example. Water molds are fungus-like protists that live as parasites or on decomposing organisms in wet soil and surface water.
What is mold in the US?
Mold (US) or mold (UK / NZ / AU / ZA / IN / CA / IE) is a fungus that develops as multicellular filaments known as hyphae. Yeasts, on the other hand, are fungi that can develop as a single-celled organism. A mycelium is a network of tubular branching hyphae that is considered a single organism.
How do fungi reproduce?
Fungi reproduce in an asexual manner via fragmentation, budding, or spore production. Hyphae fragments may form new colonies. When a fungal mycelium splits into fragments, each component grows into its own mycelium, this is known as mycelial fragmentation. Asexual spores come in a variety of forms.
Why are slime molds beneficial to the ecosystem?
Slime molds are beneficial to ecosystems because they decompose and provide essential nutrients to the environment. Because protists provide humans with oxygen, are key players in food chains, and recycle important nutrients for other living forms to utilize, you might argue that life on Earth is dependent on them.
What kingdom is a fungus like?
Fungi‐Like Protista. The Kingdom Protista was established in the 1860s as a place for the slime molds that are plant‐like in forming spores in multinucleate, erect, sporangia and having cellulose in their cell walls, animal‐like in having an amoeboid stage in their life cycle during which they creep about ingesting their food, ...
How does plasmodium reproduce?
Under some conditions, the plasmodium produces erect sporangiophores with sporangia on their tips. Meiosis takes place and haploid spores result. Like the sclerotia, the spores are resistant and able to sustain the slime mold over adverse growth periods. When conditions again are suitable for growth, the spores germinate. Some develop into amoebas that move about, feeding. Others become flagellated gametes. After a period of time, the cytoplasm of a pair of genetically different amoeboid or flagellated cells fuse, but individuality of the nuclei is retained, a process known as plasmogamy. Karyogamy, the fusion of the nuclei, soon follows after both types of unions; the resultant cells are the zygotes. Growth of a zygote and the repeated division of its nuclei by mitosis result in the characteristic multinucleate, diploid plasmodium.
What is the cause of downy mildew on grapes?
Among the terrestrial forms are several highly destructive plant pathogens—downy mildew of grapes and late blight of potatoes are caused by oomycetes. Less well known, but as significant economically, are several oomycetes that live in the soil and attack, and ultimately kill, the roots of many commercially grown fruits.
What are the oomycetes?
Another distinctive group, the oomycetes, includes the water molds and some other taxa. Some are simple unicellular forms, but there are, as well, branched, coenocytic, filamentous fungi-appearing individuals in the group.
What is the name of the slime mold that loses its cell membrane when it comes together?
Myxomycota, the plasmodial slime molds, lose their cell membranes when they come together and the nuclei float freely in the combined, membrane bound mass of cytoplasm, which is called a plasmodium. (The slug of the Dictyostelio‐mycota is a false plasmodium or a pseudoplasmodium .)
What are the two groups of slime molds?
Two principal groups of slime molds are recognized, with a third unrelated group closely associated: Dictyosteliomycota form a motile mass of protoplasm—a “slug”— by aggregating individual amoeboid cells that retain their identity in the slug, hence their common name, cellular slime molds.
Where do slime molds grow?
Like fungi these slime molds grow in damp, organic‐rich sites. Rotting logs or decaying plants on the forest floor are favorite habitats. Their amoeboid form is frequently a brightly colored orange or yellow blob of viscous, slippery protoplasm that streams slowly into a network of branching, anastomosing projections that move the whole mass forward. This is the feeding stage and bacteria, yeasts, fungi, or bits of vegetation are incorporated into the mass as it moves. Two principal groups of slime molds are recognized, with a third unrelated group closely associated:
What are fungi like protists?

What are the three groups of protists?
There are three main groups within the protists that are defined by how they acquire their nutrition: animal-like protists, plant-like protists, and fungus-like protists . Animal-like protists are known as protozoa, and they engulf and digest their food.
What are the two types of funguslike protists?
There are two major types of funguslike protists. There is the water mold group and the slime mold group , both which function as ecological decomposers. Water molds get their name because these funguslike protists live in water or in moist soil. Their role in the ecosystem is as decomposers of organic material, often dead and decaying matter. They usually use absorption to obtain these nutrients. Some water molds are parasitic in nature and will attack our healthy crops and fish, causing much damage.
How do funguslike protists get energy?
The funguslike protists are protists that get energy by absorbing or ingesting dead organic matter. When you first see them, these funguslike protists aren't cute or pretty or handsome, or what have you. In fact, they kind of look creepy. Most of them look like a weird blob of spreading goo.
What kingdom is downy mildew?
This particular species causes downy mildew on grapes. Lesson Summary. Let's review what we've learned. Protists are organisms that belong to the Protista kingdom that are eukaryotic and generally unicellular but sometimes multicellular and include most algae, protozoans, and some funguslike organisms.
What is the vegetative state of slime mold?
The vegetative state of slime molds is the state of the slime mold before it produces spores. Parasitic Funguslike Protists. Problems arise when the parasitic species of these funguslike protists attack important food crops.
How do slime molds get their name?
Slime molds get their name from the way they look. They look like slime. These funguslike protists live in moist places, such as in rotting logs in the woods. These can also live in freshwater where they ingest bogwood and other types of underwater organic matter. The role of slime molds is the same as that of water molds -- they are decomposers. Slime molds typically decompose rotting logs and leaves in forests while water molds decompose the organic matter in aquatic environments. Slime molds may use absorption or ingestion via phagocytosis to obtain nutrition. Slime molds are classified under the division myxomycota and include the mildew that you commonly see in bathrooms. Slime molds do not qualify as fungi because they do not have cell walls in the vegetative state. The vegetative state of slime molds is the state of the slime mold before it produces spores.
How many species of water mold are there?
For example, there are 500 species of oomycota water molds, and some are helpful to us while others are parasitic, such as the phytophthora infestans water mold. Water molds are not true fungi because they don't have chitin in their cell walls.
What is the role of water molds in the ecosystem?
Their role in the ecosystem is as decomposers of organic material, often dead and decaying matter. They usually use absorption to obtain these nutrients. Some water molds are parasitic in nature and will attack our healthy crops and fish, causing much damage.
What are fungus-like protists?
Fungus-like protists are heterotrophs with cell walls. They also reproduce by forming spores. All fungus-like protists are able to move at some point in their lives. There are essentially three types of fungus-like protists: water molds, downy mildews, and slime molds.
What are slime molds?
Slime Molds: Fungus-like protists that recycle organic material and they are found on forest floors, at one stage in their life cycle, they resemble amoebas and in the other stage, they form mold-like clumps that produce spores.
How do spores develop into hyphae?
Spores develop into hyphae when they find food and grow into a new organism. Sexual reproduction takes place in specialized structures that are formed by hyphae. Downy Mildews: This fungus-like protists which must absorb their food from the surrounding water or soil, or may invade the body of another organism to feed.
What is water mold?
Water Molds: This fungus-like substance thrives on dead and decaying organic matter in the water. Some are plant parasites on land. Its cell walls are made of cellulose and produce spores. They reproduce both sexually and asexually. Asexual reproduction involves hyphae (thin filaments) which develop into zoosporangia (spore cases). Flagellated spores swim away in search of food. Spores develop into hyphae when they find food and grow into a new organism. Sexual reproduction takes place in specialized structures that are formed by hyphae.
What are fungi like protists?
Fungus-like Protists. Fungus-like protists are known as molds. Like true fungi, they are heterotrophic feeders and absorb nutrients from decaying organic matter in their environment. They also reproduce using spores. However, they differ from true fungi in that their cell walls contain cellulose, rather than chitin.
What are the two types of fungi-like protists?
The two major types of fungi-like protists are slime molds and water molds.
