What does the plastron of a turtle refer to?

1. The upper shell

2. The bottom shell

3. The head region

4. The tail region

The correct answer is: The bottom shell

The plastron of a turtle refers specifically to the bottom shell. This structure is an important part of a turtle's anatomy, providing protection to its internal organs and aiding in defense against predators. The plastron is typically flatter and more shield-like compared to the upper shell, known as the carapace, which serves a similar protective function but is located on the upper side of the turtle. Understanding the plastron's role is crucial for anyone studying or working with turtles, as it can inform proper care and rehabilitation practices.
