Question

What are the $3$ types of symmetry?

Answer 1

Animal symmetry:

Repetition of parts in an animal or plant in a systematic fashion is called animal symmetry.

Types of animal symmetry:
1. Spherical symmetry:

1. In this type of symmetry, a person's body can be divided into equal parts by any plane passing through the center.
2. E.g. Wolves, some sponges, and some corals.

2. Bilateral symmetry:

1. In this type of symmetry, the body can only be divided into two equal parts by a single plane because the vital organs of the body are connected and connected on two sides of the central axis.
2. Bilateral symmetry is found in many vertebrates and all invertebrates.
3. The left and right sides of the body are called the lateral sides.

3. Radial symmetry:

1. In radial symmetry, a person's body is divided into equal parts by any plane passing from the center to the top.
2. This type of symmetry is found in synergistic, some aquatic, and echinoderms.
3. It is found in marine anemones.
