What is the difference between plant and animal cells?

Ah, good question. The main difference is the outside structure. Plant cells have a strong, rigid cell wall. It gives them a fixed, sort of boxy shape. Animal cells don't have this wall, so they are more flexible and can be different shapes.

Also, how they get energy is different. Plant cells have little green things inside called chloroplasts. They use these to make their own food from sunlight. Animal cells can't do that; we have to eat food for energy.

Finally, most plant cells have a big water sac called a large central vacuole. This helps keep the plant stiff. Animal cells don't have this big one. So, the wall, chloroplasts, and big vacuole are the main things.
