The radial symmetry is found in the animals of___________?
Correct answer: C. Cnidaria
- A. Protozoa
- B. Porifera
- C. Cnidaria
- D. All of these
Explanation
Cnidarians such as Hydra, jellyfish and sea anemones have body parts arranged around a central oral-aboral axis, producing radial symmetry. Students may choose all of these because some protozoans and sponges can show radial forms, but radial symmetry is the standard characteristic of Cnidaria in this classification.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
