Class Work: Symmetry

In class, we learned about Radial Symmetry and Bilateral Symmetry. Bilateral Symmetry is when there is only one line of symmetry in the animal or plant. For example, a frog is one living thing that is can be classified under bilateral symmetry. Animals that have bilateral symmetry have a distinct front with senses and also, to have bilateral symmetry, you have a mirror image on the other side. Plus, you move quickly since you have senses.

Did you know that animals move more slowly when they have radial symmetry? Well, they do. To have radial symmetry, you have many lines of symmetry. Unlike animals with bilateral symmetry, they don't have a distinct front. An example of a living thing that has radial symmetry is a sea star.

What animals with Radial and Bilateral symmetry both have is that the animals both have a balanced arrangement of parts. They also both perform all basic functions of life.

Some animals that have bilateral symmetry are an ant and a beaver. They both have only one line of symmetry. A plant that has radial symmetry is a sea urchin since it has many lines of symmetry. One living thing that has no symmetry is a sponge. In conclusion, animals and plants can have radial, or bilateral symmetry, or even no symmetry, depending on the living thing.
