Bilateral symmetry is a type of symmetry where an organism can be divided into two identical halves along a single plane. This means that if you draw a line down the middle, both sides will mirror each other. Many animals, including humans, dogs, and butterflies, exhibit bilateral symmetry, making it a common feature in the animal kingdom. This symmetry is important for movement and balance, as it allows for streamlined shapes that help organisms navigate their environments efficiently. In addition to animals, some plants also show bilateral symmetry, such as orchids, which can be divided into two symmetrical halves.
