What are living things made of?

Other organisms are multicellular – they are made up of many types of cells.

Some organisms are unicellular – they are made up of only one cell.

Cells are the building blocks of life.

A section through an animal cell:

cell membrane

cytoplasm

nucleus

DNA

Mitochondria

Section through a plant cell

cell membrane

Nucleus contains DNA

cytoplasm

chloroplast

large cell vacuole

cellulose cell wall

Mitochondria

What is a cell?Animal and plant cells come in different shapes and sizes, but they all have three basic features.

Plant cells also have some extra features that make them different to animal cells.

cell membrane

cytoplasm

nucleus

animal cell plant cellMost cells have three basic parts: the nucleus, cytoplasm and cell membrane. They may also contain other small structures or organelles, that perform specific jobs.

mitochondria

Comparing animal and plant cells

Found in both animal and plant cells

Found only in plant cells

cell membrane cellulose cell wall

nucleus large sap vacuole

cytoplasm chloroplast

Mitochondria

The parts of a typical animal cell

Functions of the organelles

Organelle Function

Cell surface membrane

Controls what goes in and out of the cell.Keeps the cell together.

Cytoplasm Jelly-like substance.Where the cell’s chemical reactions take place.

Nucleus Contains the DNA.Controls the cell.

Cell wall Supports the cell.Made out of cellulose.

Cell vacuole Contains cell sap.Helps support the cell

Chloroplast Contain chlorophyll, a green pigment.Make the plants’ food by photosynthesis.

Mitochondria Produce energy for the cell by respiration.
