Question
Which of the following is true of Cnidarians?
- They have organs.
- They have three cell layers.
- They have distinct tissues.
Solution
The correct answer is "They have distinct tissues."
Cnidarians, which include jellyfish, sea anemones, and corals, are characterized by their distinct tissues. They do not have organs or three cell layers. Instead, they have two main cell layers: an outer layer, or ectoderm, and an inner layer, or endoderm. These two layers are separated by a non-cellular layer called mesoglea. The distinct tissues in cnidarians include nerve tissue and muscle tissue, which allow them to have more complex movements and behaviors compared to other simple organisms.
