Which of the following have porous body and are diploblastic?
1 Aurelia and Obelia
2 Adamsia and Euplectella
3 Leucosolenia and Spongilla
4 Sycon and Hydra
Explanation:
C Leucosolenia and spongilla have porous body and are diploblastic. Both are belonging to phylum porifera means pore bearing. So they have pore throughout their body.

What is the range of length of sponges?
1 $1 \mathrm{~mm}-10 \mathrm{~mm}$
2 $1 \mathrm{~cm} \quad-1$ metre
3 $1 \mathrm{~mm}$ - $100 \mathrm{~mm}$
4 1 metre - 10 metre
Explanation:
B Some sponges are about a centimeter long and may be even less than a centimetre. Some sponges which are vase like or cylindrical are up to 1 or 2 metre long. - Sponges have a high efficiency and capacity for particle retention preferably small particle $(<10 \mu \mathrm{m})$ such as bacteria, phytoplankton viruses and dissolved organic matter. - The range of length of sponges is $1 \mathrm{~cm}-1$ metre.

Which of the following features is universally present in all sponges?
1 marine habitat
2 presence of spicules
3 presence of spongin fibres
4 presence of spongocoel
Explanation:
D All sponges have a central body cavity known as spongocoel which is lined by choanocytes or collar cells. Hence, the thing which is common for all sponges is spongocoel. - Sponges may be marine (eg-sycon) or fresh water (eg - spongilla)
