Plant cells have several structures that animal cells lack, giving them unique characteristics:

1. Cell Wall: A rigid outer layer made of cellulose, providing structural support and protection.

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

3. Vacuole: A large, central sac filled with water and dissolved substances, providing turgor pressure for cell shape and storage.

4. Plasmodesmata: Tiny channels connecting the cytoplasm of adjacent plant cells, allowing communication and transport.
