choanocytáik
Choanocytáik, commonly known as collar cells, are specialized flagellated cells found in sponges and some other lower metazoans. These cells are primarily responsible for feeding and respiration within the organism. Each choanocyte is characterized by a single flagellum that beats rhythmically, creating a water current. Surrounding the base of the flagellum is a collar of microvilli, which are short, finger-like projections.
The beating of the flagellum draws water into the sponge through small pores. As water passes through
In addition to their role in feeding, choanocytes also play a crucial part in gas exchange. The
