Question

Water currents in Leucosolenia are produced by

• A. Choanocytes
• B. Pinacocytes
• C. Archaeocytes
• D. Thesocytes

Answer 1

The correct option is A Choanocytes

Choanocytes are flagellated collar shaped cells lining the cavity of sponges such as Leucosolenia. The beating of their flagella produces water current which helps in the filtering of food particles, respiratory exchange, and removal of wastes. Pinacocytes are flat cells covering the outermost layer of sponges. Archaeocytes are amoeboid cells in sponges that are pluripotent. The thesocytes are food storing cells in sponges.

Thus, the correct answer is option A.
