2. What are cells?
âą All living things are made of cells
âą A living thing is called an organism
âą Plants and animals are organisms
âą Cells are like the âLego bricksâ â they are
the building blocks of life â small units
that make up larger structures
âą Weâre going to look at Animal and Plant
cells
6. 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.
10. Part of Cell Function
Nucleus
Cytoplasm
Cell membrane
Vacuole Contains a watery liquid called cell sap
Chloroplast
Contain a green chemical â chlorophyll â
responsible for photosynthesis
Cell wall
Provides strength and support and
helps to maintain shape
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
11. Similarities and Differences
BOTH animal and plant
cells have
ONLY plant cells have:
Nucleus Cell wall
Cytoplasm Vacuole
Cell membrane Chloroplasts
The typical plant and animal cells look
different to each other â they are
different shapes and the nucleus is in a
different position.

cell membrane, in both cells, allows entry and exist of small molecules to enter and exit the cell ( the cell is said to be SEMI PERMEABLE)
