Question

what is the purpose of the cell at letter b?

to replace gustatory cells that are damaged

to maintain the opening of the taste pore

to sense certain types of taste molecules

to secrete neurotransmitter on the neurons at a

Explanation:

This is a question about taste cells (likely a taste bud diagram). Gustatory (taste) cells have specific functions. The cell at B (gustatory cell) is responsible for sensing taste molecules. The first option is for basal cells (replacing damaged gustatory cells), the second is about pore maintenance (not gustatory cells), and the fourth is about neurotransmitter secretion (but sensing is primary for gustatory cells here). So the correct option is the one about sensing taste molecules.

Answer:

C. to sense certain types of taste molecules
