Question

Water current in Leucosolenia is produced by

• A. archaeocytes
• B. collencytes
• C. choanocytes
• D. pinacocytes

Answer 1

The correct option is C choanocytes

Water current in Leucosolenia is produced by flagellated choanocytes. Leucosolenia is a genus of calcareous sponges. Species of this genus usually appear as groups of curved vases. They are up to 2 cm long and each ends in an osculum.

Archaeocytes are regenerative cells found in sponges. They can differentiate and form any cell that is a part of a sponge.

Collencytes are cells found in mesohyl which secretes fibrous gluey substances.

Pinacocytes are flat cells found on the surface of the body of a sponge.
