General Characteristics of Protista
- They are mostly unicellular but some are multicellular and colonial organisms.
- They are either free-living or parasitic.
- They have aerobic mode of respiration and have mitochondria for cellular respiration.
- They are true eukaryotes and are nucleated.
- They have (9+2) arrangement of flagella and have membranous organelles.
Which type of protists is most like a plant?
Protists are mainly classified into three groups, namely:
- Protozoa ( Animal-like protists )- They cannot make their food (heterotrophs) and feed through ingestion or absorption.
- Algae ( Plant-like protists )- They make their food through photosynthesis, hence autotrophs.
- Slime and water molds ( Fungus-like protists )- These protists cannot manufacture their food, hence heterotrophs.
What are the harmful effects of plant like protists?
- How much of the total photosynthesis on the globe is carried out by phytoplankton? What does this mean for aquatic ecosystems?
- How are the flagella of dinoflagellates arranged?
- What organisms have dinoflagellates as symbiotes? Why are dinoflagellates important to these organisms?
- How do bivalves respond to red tides? What does this mean for humans?
What are three types of plant-like protist?
Plant-Like Protists : Definition, Characteristics and Classification
- Euglenophyta
- Chrysophyta (Golden Algae)
- Baccilariophyta (Diatoms)
- Pyrrophyta / Dinoflagellata (fire algae)
- Chlorophyta (green algae)
- Phaeophyta (brown algae)
- Rhobdophyta (Red Algae)
What are the six phyla of plant like protists?
The following animal-like protists are heterotrophs without hair-like movement structures:
- Rhizopoda
- Actinopoda
- Foraminifera
What are 3 characteristics of protists?
Characteristics of ProtistsThey are eukaryotic, which means they have a nucleus.Most have mitochondria.They can be parasites.They all prefer aquatic or moist environments.
What are the 3 classifications of protists?
Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists.
What are protist with plant like characteristics called?
Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, algae contain chlorophyll and make food by photosynthesis.
What are the characteristics of plant like protists quizlet?
Spherical, rodlike, and spiral.
What are the 3 structures that protists use to move?
Protists have three types of appendages for movement. As shown in Figure below, they may have flagella, cilia, or pseudopods (“false feet”).
What are the general characteristics of protists?
Protists have nuclear membranes around their DNA. They also have other membrane-bound organelles. Many protists live in aquatic habitats, and most are motile, or able to move. Protists have complex life cycles that may include both sexual and asexual reproduction.
What are the 6 types of plant-like protists?
A. TypesRed Algae. a. Group containing most of the world's seaweeds. b. ... Brown Algae. a. The algae that live in colder climates are mostly brown algae. b. ... Green Algae. a. They are green because the chlorophyll is the main pigment they have. b. ... Diatoms. a. Singlecellular. b. ... Dinoflagellates. a. Most are single cell. b. ... Euglenoids.
How are plant-like protists distinguished from other protists?
Protists can be multicellular or unicellular organisms. Plants are all multicellular and exhibit cellular differentiation. Protists can be autotrophs, heterotrophic consumers, or decomposers. Plants are primarily autotrophic producers.
Do plant-like protists have cell walls?
Protists that are similar to animals do not have cell walls at all. Plant- and fungi-like protists have cell walls that are similar to plants. Other protists have a unique cell wall that is different from cell walls seen in other eukaryotic kingdoms.
Do plant-like protists have flagella?
Most protists move with the help of flagella, pseudopods, or cilia.
How are animal like and plant-like protists similar and different?
The plant protists are autotrophs, except fungi, while the animal protists are heterotrophs. The plant protists photoynthesize (except fungi), while animal protists are not able to photosynthesize.
How are animal like protists classified?
Animal like protists are single-celled consumers. 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.
What protist has a chloroplast?
Protists that possess chloroplast are plant-like protists or algae. They include green algae, red algae, diatoms, brown algae, dinoflagellates, and...
Why are they called plant-like protists?
They are called plant-like protists since they can carry out photosynthesis just like plants. However, they are devoid of roots, stems, leaves, phl...
What are 3 characteristics of plant like protists?
Characteristics of plant-like protists include: they are aquatic, eukaryotic organisms, they possess a flagellum that is used for locomotion, and a...
Why are protists called plant like?
Protists are called plant-like since they can manufacture their food through the process of photosynthesis. This is because they possess a chloropl...
Do protists carry out photosynthesis without chloroplasts?
Photosynthesis involves the conversion of solar energy to chemical energy. The absorption of the solar energy is performed by the chlorophyll conta...
