Choanocyte or collar cells is a unique type of porifers which contains a flagellum surrounded at its base by a thin cytoplasmic collar. This cell creates current and ingest food particles from water.

Are choanocytes significant to a fundamental process for sponges?

Yes, choanocytes are significant in sponges for feeding and the ingestion of food particles. They create water currents that bring in nutrients which are then captured by their collar cells for consumption. Choanocytes also play a role in reproduction by generating sperm cells.


What cell type in sponges is responsible for producing the water current through the sponge?

Collar cells, also known as choanocytes, are responsible for producing the water current through sponges. These specialized cells have flagella that generate the current, bringing in food and oxygen while expelling waste.


What is the function of choanocytes in reproduction of sponges?

Choanocytes in sponges function in producing sperm and eggs, as well as in the development of embryos. They help to capture and process sperm in sponges that are hermaphroditic (contain both male and female reproductive organs) and assist in releasing the developing embryos for sexual reproduction.


What are the cells of a sponge that capture food particles called?

The cells of a sponge that capture food particles are called choanocytes. These specialized cells have a flagellum that creates water currents to bring in food particles, which are then trapped and ingested by the choanocytes.


What name is given to the food-trapping cells of sponges?

Choanocytes


What are the major cell types in sponges?

Sponges primarily consist of three major cell types: choanocytes, amoebocytes, and pinacocytes. Choanocytes, or collar cells, are responsible for capturing food particles and creating water currents through the sponge. Amoebocytes play a versatile role, aiding in digestion, nutrient distribution, and reproduction. Pinacocytes form the outer protective layer of the sponge, providing structure and regulating water flow.


What are the specialized cells that use flagella to move a steady current of water through a sponge?

Choanocytes


What is an ascon?

An ascon is a cavity, in the form of a bag or tube, lined with choanocytes, which forms the structure of 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.


What are the cells called that move throughout the sponge body wall to deliver food to the organism's cells?

The cells are called choanocytes. Choanocytes move throughout the sponge body wall and help to capture and digest food particles, which are then delivered to other cells in the organism for nourishment.


What structures supplies food and oxygen to the sponge?

The pores of the sponges are responsible for the supply of food and oxygen. As they are SESSILE (fixed at one place) so they can't move to catch their prey, but their pores do the work for them......


Do sponges have specialized cells?

it has no muscles thats how it can function
