Most cells have the following structures:
- Cell membrane: Holds the cell together and controls what can enter and leave the cell.
- Cytoplasm: This is a watery, jelly-like fluid in which the other structures are suspended.
- Nucleus: It contains genetic information in the form of DNA. The nucleus controls cell activities.
- Small Vacuole: Used for the temporary storage of food and waste.
- Mitochondrion: Releases energy from glucose
Plant Cells
Plant cells have extra structures that are not found in animal cells:
- Chloroplasts: Contain the green chemical called Chlorophyll which allows plants to make their own food from carbon dioxide and water using the suns energy. This is a process called photosynthesis.
- Cell wall: This tough structure is made from cellulose, located outside the cell membrane. It gives the plant cell support and structure.
- Large Vacuole: Stores water, sugar and waste and helps give support to the cell.
