Answer:
Plant cells can be larger than animal cells. ... Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include chloroplasts, the cell wall, and vacuoles.
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

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.
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.
