Question

Which of the following sponge characteristic is not typical of animals?

• A. They practice sexual reproduction
• B. They have the cellular level of organization
• C. They are asymmetrical
• D. Both (b) and (c)

Answer 1

The correct option is D Both (b) and (c)

Sponges lack true tissues and organs and have a cellular level of organisation. Some of them are radially symmetrical, but most are asymmetrical. These two features distinguish them from other animals that have tissue or organ level of organisation and bilateral or radially symmetrical body.

So, the correct option is 'Both (b) and (c)'.
