Explanation:

Sponges are simple organisms without complex brains, fins for swimming, or the ability to fly. However, they have a unique ability to reassemble after being separated. This is due to their cellular plasticity and the presence of specialized cells called amoebocytes. When a sponge is fragmented, these cells can migrate and differentiate to form a new sponge.

Answer:

They can reassemble after being separated
