1P9: Monday 22nd November

What are cells?

• All living things are made of cells

• A living thing is called an organism

• Plants and animals are organisms

• Cells are like ‘Lego bricks’ – they are

the building blocks of life – small

units that make up larger structures

Nucleus

Cytoplasm

Cell membrane

Animal Cell

Part Function

Nucleus

Cytoplasm

Cell Membrane

Controls all cell activities

Liquid centre of a cell where chemical reactions happen.

The border of a cell which controls what goes in and out of the cell. It only allows small molecules to pass through it and so is known as semi-permeable.

Cytoplasm

Cell membrane

Vacuole Contains a watery liquid called cell sap

ChloroplastContain a green chemical – chlorophyll – responsible for photosynthesis

Cell wallProvides strength and support and helps to maintain shape

Similarities and Differences

BOTH animal and plant cells have:

ONLY plant cells have:

Nucleus Cell wallCytoplasm VacuoleCell membrane Chloroplasts

The typical plant and animal cells look different to each other – they are different shapes and the nucleus is in a different position.
