• Cells are the building blocks of life.

• They were named by Robert Hooke as

he thought they looked like the tiny
rooms that monks lived in.

Cells: Key Points

• Some organisms can live alone as

just one cell.

• Some organisms, like humans,

daffodils and dogs are made up of
many different types of cells.

Cells: Key Points

This is an amoeba, an example
of a single-celled organism.

Multiple Select

Multiple Choice

A cell is...

• the basic unit of structure and function in living organism

Most animal cells have some key features inside of them:

• A place where the cell’s activities are controlled.

• A place where chemical reactions happen.

• A place where substances can pass in and out of the cell.

• A place where energy is released for the cell.

and out of the cell.

D. A place where energy is released for the

cell.

nucleus: Controls the activities of the cell. Contains genetic material (DNA),
which is packaged into structures called chromosomes.

cell membrane: Controls the movement of substances into and out of the cell.

cytoplasm: A jelly-like substance that fills the cell, where most chemical
reactions happen.

mitochondria: Contains the enzymes needed for aerobic respiration, which
releases energy for the cell.

Inside Plant Cells

Pause for Thought
What do you recognise in this plant cell?

Inside Plant Cells

Most plant cells have the same four
features inside of them as animal cells.

They also have three extra features:

• A place where light is captured for

photosynthesis.

• A place where cell sap is stored.

• A place to help support and

strengthen the cell.

Inside Plant Cells

A. A place where light is captured
for photosynthesis.

B. A place where cell sap is stored.

C. A place to help support and
strengthen the cell.

A

B

C

chloroplasts: Contain the pigment chlorophyll which absorbs light to provide energy
for photosynthesis.

cell wall: A rigid structure that helps to strengthen the cell and provides support for
the plant

permanent vacuole: Filled with cell sap to keep the cell rigid to support the plant.
