Question

Look at the picture above carefully. It represents the transportation inside a sea sponge.

“This organism has a circulatory system”.

• A. True
• B. False

Answer 1

The correct option is B

False

Sponges are very simple animals. They rely on the flow of water through their body for their needs. Oxygen and carbon dioxide directly diffuse in and out of their body through water. They do not have a specialized circulatory system for transporting nutrients and oxygen. Waste products are also directly excreted into the water around them.
