Answer 2

Answer:  

In sponges, the free-swimming larva is called the parenchymula.

Explanation:

This sponge is a free-swimming sponge which can be found in its larval stage. It has got an elongated body which consists of ectodermal and entodermal cells (also known as parenchyma) that can be found in mass numbers.  

Parenchymula settles to the bottom and gets attached to coelenterates which then changes into the planula stage.

In this sponge, the area given for non-flagellate cells is very less.
