Answer:
- Animal cells
Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:
- Nucleus – This contains genetic material (DNA), and controls the cell's activity.
- Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.
- Cytoplasm – A jelly-like substance where the chemical reactions happen.
- Mitochondria – This is where energy is released from the food molecules.
2. Plant cells
Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:
- Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
- Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.
- Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.
