What are the two levels of organization in animals?
Level of Organization. Depending on the organization of cells, animals are grouped into 2 categories, namely, parazoans (shows cellular level) and eumetazoans (shows tissue level or organ level or organ system level or organization). i. Cellular Level – In this, cells are not organized into tissues.
What are the members of the phylum of sponges?
The members of this phylum are commonly known as sponges. These are pore bearing animals and exhibit the following general characters:#N#1. These poriferans are the most primitive multicellular animals that show a cellular level of organization.#N#2. Poriferans bear numerous minute pores called Ostia on the body wall, which lead into a central cavity called spongocoel or perigastric cavity. The spongocoel opens to outside by osculum.#N#3. They may be solitary or colonial found attached to a substratum leading a sedentary life.#N#4. Spongocoel and the canals are lined by special cells called choanocytes or collar cells.#N#5. Digestion is intracellular; respiration and excretion occur through the body wall by diffusion.#N#6. Reproduction is by asexual or sexual methods.
What are the two groups of cells that are placed in the early stages of embryonic development?
On the basis of a number of germ layers, animals are placed in two groups, i.e., diploblastic (embryo is two-layered consisting of outer ectoderm and inner endoderm) and triploblastic (embryo is three-layered consisting of outer ectoderm, middle mesoderm and inner endoderm).

In general, animals are divided into two main groups namely, vertebrates (animals with a backbone) and invertebrates (animals that lack a backbone).
Why are hemichordates considered to be the link between vertebrate and invertebrate animals?
They exhibit bilateral symmetry and thus the body can be divided into two equal halves. Because they share several characteristics with chordates and members of the Phylum Echinodermata , Hemichordates are sometimes considered to be the link between vertebrate and invertebrate animals.
Which phylum has a dorsal nerve cord and a notochord?
While the majority of animals in the Phylum Chordata have a vertebrate (the majority of higher animals), the group also consists of protochordates (e.g. squirts and amphioxus) which are closely related to vertebrates. While they lack a backbone which is present in all vertebrates, these organisms have a dorsal nerve cord and a notochord and thus qualify to be classified under the Phylum Chordata.
How many classes of vertebrate are there?
Vertebrate animals are classified into seven main classes that include:
What kingdom is a plant cell?
The Kingdom Animalia is a large group that consists of eukaryotic, multicellular organisms that are heterotrophic in nature. As such, they obtain their nutrition from external sources. Although they are unable to produce their own food, which is one of the main defining characteristics of plants, animal cells lack a cell wall that is present in plant cells.
Where is the mesoderm located?
For this reason, the majority of animals with a coelom have a mesoderm. It's located between the body wall of an organism and the alimentary canal. Some examples of these cavities in the body include the peritoneal cavity and the space around the lungs.
What is the classification of animals?
Animal classification is the categorizing of animals and organisms hierarchically. The ranking system is based on a fixed number of levels such as kingdom, family, or genus. The order goes: Animal classification is based on an organisms decent from a common ancestor. Accordingly, the most important traits for classification are those inherited ...
How many ranks are there in the animal kingdom?
The animal kingdom is separated into nine taxonomic ranks: Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species. Though this is the true classification for animals, the first two ranks are often omitted, and on occasion, an extra one - subfamily- is added. Take the lion, for example. Below is the animal classification ...
What are the traits that are important for classification?
Accordingly, the most important traits for classification are those inherited from a common ancestor. An example would be birds and bats, which both can fly, but this characteristic is not used to classify them into a class because they did not inherit this from a common ancestor.
How many levels of classification are there?
Know and understand the seven levels of classification.
How many phyla are there in the animal kingdom?
Within the animal kingdom, the animals are divided into more than 30 phyla (which is the plural of “phylum”). You might be interested in Phylum Chordata — it’s the one humans and all animals with backbones are in (do you see how “chordata” looks like the word “cord” — like spinal cord?).
What is the phylum of arthropods?
Phylum Arthropoda contains insects, spiders and other animals with segmented bodies, like shrimp. Arthropods have their skeletons on the outside of their bodies (think of the hard shell of a lobster) and other characteristics in common.
What does it mean when an animal is called a species?
When an animal is called by its scientific name, then that means it is being identified by its genus and species . We use a lowercase letter and italics for the species. The scientific name of dogs is Canis familiaris; however, the scientific name of wolves is Canis lupus.
What is the only part of an animal's name you will make up yourself?
That means that the only part of the animal’s name you will make up yourself is the actual species name. You go back to the Animal Diversity Web to find the closest animal you can find to the one you discovered.
How to tell if an animal is different from another animal?
Look at several other species within the genus so that you can think of something that makes your animal slightly different than any other species in the genus. For example, it could be a different color or eat something different or live on a different continent.
What is it called when you put animals in order?
Maybe you will make a change in how animals are organized! Putting animals in order like this is called taxonomy. The taxonomists — people who name animals — use a book called the International Code of Zoological Nomenclature, or ICZN, to tell them the rules for classifying animals. Linnaeus’s system has seven levels:

What is cladistic classification?
Cladistic classification uses concepts like homologous structures, along with other forms of evidence (like DNA sequences), to pinpoint probable common ancestors between organisms. This is in keeping with the Darwinian theory of common descent. “Science is the systematic classification of experience.”.
What is Animal Classification?
Animal kingdom classification is an important system for understanding how all living organisms are related. Based on the Linnaeus method, species are arranged grouped based on shared characteristics.
How many branching categories are there in animal classification?
The more features that a group of animals share, the more specific that animal classification group is. Every species is defined based on nine branching categories. The primary method of animal classification is:
What kingdom contains all bacteria in the world?
Eubacteria – Single celled organisms found in everything from yogurt to your intestines. This kingdom contains all bacteria in the world not considered archaebacteria. Archaebacteria – The oldest known living organisms. Single-celled and found in hostile and extremely hot areas like thermal vents or hot springs.
How are animals named?
Each individual species within the genus is named after its individual features and characteristics. The names of animals are based in Latin and consist of two words. The first word in the name of an animal will be the genus, and the second name indicates the specific species. This method of organizing scientific names of animal species was developed by Carl Linnaeus in the 1700’s. As an example, a dolphin species name is Delphinus Delphis. A red fox is Vulpes vulpes. This animal classification chart of a red fox is an example of Linnaean Taxonomy
