Question

Collencytes of sponges are concerned with production of

• A. Collagen fibres
• B. Spicules
• C. Spongin fibres
• D. Both B and C

Answer 1

The correct option is A Collagen fibres

Collencytes are the amoebocytes with branched pseudopodia. These can be compared with the connective tissue cells and are often united into a syncitial network. These cells produce collagen like protein.

On the other hand, spicules and spongin fibres are produced by scleroblasts. Scleroblasts may be calcoblasts (produce calcareous spicules) or silicoblasts (produce siliceous spicules) or spongioblasts (produce spongin fibres).

So, the correct answer is 'Collagen fibres'.
