- Chloroplast: Chloroplasts are organelles found in plants and algae that contain chlorophyll and are responsible for photosynthesis. Animals do not contain chloroplasts because they do not perform photosynthesis.
- Cell Wall: Plant cells have a cell wall made of cellulose, pectin, and other polysaccharides that provide support and protection for the cell. Animal cells do not have a cell wall.
- Vacuoles: Plant cells have large central vacuoles that store water, ions, and other nutrients. Animal cells may have small vacuoles that perform a variety of functions.
