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.

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.
What do Azure Vase Sponges eat?
Azure vase sponges are filter feeders, meaning they primarily capture and consume plankton and other small particles from the water. They use specialized cells called choanocytes to filter out food particles and absorb nutrients.
What has the name haliclona?
Haliclona is a genus of marine sponges, commonly found in oceans worldwide. These sponges are known for their filter-feeding behavior, where they extract food particles from the water using specialized cells called choanocytes. Haliclona sponges play a vital role in marine ecosystems by providing habitat and food for various organisms.
How does fragmentation in sponges differ from reproduction in reptiles?
Fragmentation in sponges involves breaking off a piece of the sponge that grows into a new individual, while reproduction in reptiles usually involves sexual reproduction where eggs are fertilized internally or externally. Sponges can regenerate lost parts easily through fragmentation, while reptiles rely on more complex reproductive strategies to produce offspring.
What is the sponges body covering?
Sponges belongs to family of coral reefs. their body is cvered with fibrous matter and the final last layer is covered the hard covering made up of Calcium carbonate. the outer covering of calcium carbonate helps them to protect them selves from their predators
Do sponges have specialized cells?
Yes, sponges have specialized cells called choanocytes that help with feeding by creating water currents. They also have specialized cells called archaeocytes that aid in digestion and regeneration.
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 name is given to the food-trapping cells of sponges?
Choanocytes
Which term is not associated with sponges?
Of the choices choanocytes, medusa, spicules, or gemmules, Medusa is the option that is not associated with sponges.
Do sponges or cnidarians have a gastovascular cavity?
No, they are from the Phylum Porifera.
What is involved in both the feeding and the sexual reproduction in sponges?
In feeding, sponges use specialized cells called choanocytes to create water currents that bring in food particles, which are then engulfed and digested. In sexual reproduction, sponges can reproduce either sexually through the release of eggs and sperm into the water for external fertilization, or asexually through budding or fragment regeneration.
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.
Why porifera is characterised by choanocytes cells?
choanocyte cells are the cells lining the inner side of the sponges tiny bodies. It plays an important role in material transportation in and out of the sponges.
What are choanocytes responsible for?
Choanocytes are responsible for generating water currents and capturing food particles in sponges. They have a flagellum that creates the current and a collar of microvilli that trap and engulf food particles. Choanocytes play a crucial role in filter feeding and nutrient uptake for sponges.
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.
Where is collar cell found?
Collar cells are found in sponges, which are simple aquatic animals belonging to the phylum Porifera. These specialized cells line the interior of the sponge and have a collar-like structure that helps to filter and trap food particles from the water.
