Here are 3 structures found in plant cells that are not in animal cells:

1. Cell Wall: A rigid outer layer composed of cellulose that provides structural support and protection.

2. Chloroplasts: Organelles responsible for photosynthesis, containing chlorophyll which captures sunlight energy.

3. Large Central Vacuole: A large, fluid-filled sac that stores water, nutrients, and waste products, contributing to cell turgor (rigidity).
