Question

Amoebocytes are found in sponges inside

• A. Pinacoderm
• B. Gastroderm
• C. Mesogloea
• D. All the above

Answer 1

The correct option is C Mesogloea

A. Pinacoderm is the outer layer of body wall of sponges consisting of flattened pinacocytes.

B. Gastroderm or gastral epidermis is the inner layer of body wall of sponges consisting of specialised flagellated cells called choanocytes or collar cells.

C. Mesoglea, also known as mesenchyme, is the inter connecting proteinaceous gelatinous matrix. Amoebocytes of various types are found moving in between thin layer such as archaeocytes, myocytes, chromocytes, thesocytes etc.

Hence, in sponges, amoebocytes are found inside mesoglea.

So, the correct answer is 'Mesoglea'.
