Why are sponges classified as an animal?
Sponges are classified as animals because they are multicellular, heterotrophic organisms that lack cell walls. They also have specialized cells and tissues, even though they lack complex organ systems.
What is the name of the specialized cell where food is collected in sponges?
The specialized cell in sponges where food is collected is called choanocyte. Choanocytes have a flagellum that creates water flow, allowing them to capture food particles and absorb nutrients.
What is the cell some animals only have?
Some animals, particularly certain types of sponges and jellyfish, primarily have specialized cells rather than true tissues or organs. For example, sponges possess unique cells called choanocytes, which help in feeding and water flow. Jellyfish have cnidocytes, specialized cells that contain stinging structures used for capturing prey. These specialized cells allow these animals to perform essential functions despite their simple body structures.
Where is collar cell found?
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
How does Barrel sponges eat?
Barrel sponges are filter feeders that capture plankton and organic particles from the water using specialized cells called choanocytes. These choanocytes have flagella that create water currents, bringing in food particles that are then absorbed by the sponge's cells for nutrition.

Do sponges have tissues?
No, sponges do not have true tissues like other animals. They are classified as Porifera and are considered the simplest animals, lacking specialized tissues and organs. Sponges have a porous body structure with specialized cells but no distinct tissue layers.
What level of organization are missing in sponges?
sponges have cellular level organisation meaning that their cells are specialized so that different cells perform different functions
What do jellyfish and sponges have that specialized venomous cells used for defense and to help capture prey?
nematocyts :)
The collar cells of sponges are similar to?
The collar cells of sponges are similar to choanocytes, which are specialized cells found in both sponges and some types of colonial protozoa. These cells have a collar-like structure with a flagellum that helps in creating water currents to bring in food particles for the sponge to consume.

Are sponges living oganism?
Yes they are, Sponges are animals of the phylum Porifera (pronounced /pɒˈrɪfərə/). Their bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells. While all animals have unspecialized cells that can transform into specialized cells, sponges are unique in having some specialized cells that can transform into other types (Source wikipedia) I also have a couple of them living with me at home but that's another story.
Are sponges unicellular?
If you're talking about kitchen sponges, they do not have cells. However, sea sponges have cells.
Where is collar cell found?
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
What is the digestive system for phylum porifera?
Sponges have a cavity lined with specialized cells that absorb the food that enters or is swept in by cilia. Not very complex.
How do sponges digest food and what is the process involved?
Sponges digest food by filtering water through their bodies and trapping tiny particles in their cells. Once the particles are trapped, specialized cells called choanocytes break down the food into smaller pieces. These smaller pieces are then absorbed by other cells for energy and nutrients. This process allows sponges to obtain the necessary nutrients for survival.
