Front

What is bilateral symmetry?

Back

Bilateral symmetry is when an organism can be divided into two parts that are nearly mirror images of each other along a central axis.

Front

What is radial symmetry?

Back

Radial symmetry is when an organism can be divided into similar halves by multiple planes passing through a central axis.

Front

What is asymmetry?

Back

Asymmetry refers to organisms that do not have a symmetrical shape and cannot be divided into similar halves.

Front

What is trilateral symmetry?

Back

Trilateral symmetry is a rare form of symmetry where an organism can be divided into three similar parts.

How can you identify an organism with bilateral symmetry?

Back

You can identify it by observing that it can be divided into two equal halves that are mirror images.

Front

What is the central axis in symmetry?

Back

The central axis is an imaginary line that divides an organism into symmetrical parts.
