Answer 1

Answer:

collar cells

Explanation:

Collar cells or choanocytes are specialized cells, that are characteristic of Phylum Porifera.

Each choanocyte consists of a central flagellum or cilium which is surrounded by a collar of microvilli. The function of choanocytes is to create water current by beating the flagellum or cilium, the food particles in the water are filtered by the microvilli and is digested intracellularly.

So, the correct answer is 'Collar cells'
