Give three differences between plant cell and animal cell. class6
Answers
Answer:
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.

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.
