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.
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 structure and function of the porifera digestive system?
The digestive system of porifera, also known as sponges, is simple and lacks specialized organs. They have pores through which water enters, bringing in food particles. The food is then digested by specialized cells called choanocytes, and waste is expelled through the same pores. This process helps sponges obtain nutrients and remove waste from their bodies.
What kind of fertilization do sponges use in their reproductive process?
Sponges use internal fertilization in their reproductive process.
Can you Briefly describe the physiological process of nutrition respiration and excretion in a sponge?
As water passes through the sponge particles are trapped and engulfed by choanocytes that line the body cavity. as water moves through the sponges, oxygen is diffused into the cells and carbon dioxide and other wastes such as ammonia is diffused out of the cells see explanation for solution.
What name is given to the food-trapping cells of sponges?
Choanocytes
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.
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.
How does an organ molecule pass into a sponges cell?
In sponges, organ molecules pass into cells primarily through a process called phagocytosis. Specialized cells called choanocytes create water currents that draw in food particles and organic molecules. Once inside, the choanocytes engulf these particles, enclosing them in a food vacuole, where digestion occurs. This efficient system allows sponges to obtain nutrients directly from their environment.
Do sponges have specialized cells?
it has no muscles thats how it can function
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.
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.
What in the sponge transports and digests nutrients?
In sponges, the transport and digestion of nutrients occur through a specialized system involving choanocytes, which are flagellated cells that create water currents and trap food particles. The trapped food is then phagocytized by the choanocytes or passed to amoebocytes, which distribute nutrients throughout the sponge's body. This cellular-level digestion allows sponges to efficiently process and utilize nutrients without a centralized digestive system.
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.
