In plant cells, there are specific structures that are not found in animal cells. These include:
- Cell Wall: Provides structure and support to the plant cell.
- Chloroplasts: The site of photosynthesis, containing chlorophyll.
- Central Vacuole: A large vacuole that holds materials and wastes, and helps maintain turgor pressure.
Assuming A, B, C, and D represent these or similar structures, you would need to identify which structures correspond to these definitions to answer your question correctly.
Please provide more information on what structures A, B, C, and D specifically refer to, and I can help clarify which includes those unique to plant cells.
