Question

sponges transport their food by
a)pinocytes
b)tropcytes
c)choanctyes​

Answer 1

Explanation:

In some sponges, amoebocytes transport food from cells that have ingested food particles to those that do not. For this type of digestion, in which food particles are digested within individual cells, the sponge draws water through diffusion

Answer 2

Choanocytes

Explanation:

• Sponges belongs to the phylum porifera.

• The choanocytes are the collar cells present in sponges.
• Sponges are the organisms found in the Phylum porifera which are also known as pore bearers.
• These are the simplest organisms with least complexity and comes in the topmost level in kingdom Animalia.

• These cells are specifically related to the regulation/ circulation of water across paragaster (or also known as spongocoel).
• The choanocytes bear flagella that helps in the movement of water and helps in entrapment of the organisms.
• Hence, the choanocytes are the cells which are considered to help in transport of food in sponges.
