Question

Define plant cell and animal cell

Answer 1

Cells are the basic unit of a living organism and where all life processes are carried out. Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.

Answer 2

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.

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.
