Question

which of the following cells uses a flagella to create currents pulling food into collar for filtering? a. choanocytes b. pinacocytes c. mesenchyme cells

Explanation:

Choanocytes, also known as collar - cells, have a flagellum that creates water currents to pull food particles into the collar for filtering. Pinacocytes are flat cells that form the outer layer of sponges and are not involved in this function. Mesenchyme cells are amoeboid cells in sponges with various functions like producing skeletal elements but not for creating food - filtering currents with flagella.

Answer:

A. choanocytes
