Fascinating Fact:

The first person to see a cell under a microscope was Robert Hooke in 1665.

In KS3 Science, you will learn about cells, their parts such as nuclei and membranes, and how they provide structure and function to every living organism.

Key Terms

Nucleus: The control centre of a cell that contains DNA.
Cell Membrane: A thin layer that surrounds the cell and controls what enters or leaves.
Cytoplasm: A jelly-like fluid inside the cell where chemical reactions happen.

Frequently Asked Questions (Click to see answers)

What are cells in KS3 Science?

Cells are the smallest units of life. They carry out essential processes to keep organisms alive, like producing energy and reproducing.

Who discovered cells first?

Cells were first observed by Robert Hooke in 1665 when he looked at cork under a microscope and saw tiny box-like structures.

Why are cells important to living things?

Cells are important because they provide structure, produce energy, and carry out vital processes that allow plants, animals, and humans to survive.

Science Quiz - Cells 01 (Answers)

1.

Which of the following is NOT present in an animal cell?

[ ]	Cell membrane
[x]	Cell wall
[ ]	Cytoplasm
[ ]	Nucleus

A cell wall is made from cellulose

2.

Which part of the cell passes on information to new cells?

[ ]	Cell wall
[ ]	Cytoplasm
[x]	Nucleus
[ ]	Vacuole

The nucleus contains DNA (deoxyribonucleicacid)

3.

Which part of a plant cell absorbs energy from the Sun?

[ ]	Cell membrane
[ ]	Cell wall
[x]	Chloroplast

Chloroplasts contain chlorophyll

4.

Which gas in the air is absorbed by plants?

[x]	Carbon dioxide
[ ]	Nitrogen
[ ]	Oxygen
[ ]	Sulfur dioxide

This gas enters plants through tiny pores on the underside of their leaves. The pores are created by a pair of guard cells

5.

[ ]	To transport glucose
[ ]	To transport minerals
[x]	To transport oxygen
[ ]	To transport water

All cells require oxygen to release energy

6.

What is a feature of a ciliated cell?

[ ]	Contains haemoglobin
[ ]	Has a tail
[ ]	Has branches at the end
[x]	Has hairs

The cells lining your windpipe have special cilia that move backwards and forwards to sweep dirt and mucus from the lungs

7.

Which of the following does NOT contain a nucleus?

[ ]	Neuron cells
[x]	Red blood cells
[ ]	Root hair cells
[ ]	Sperm cells

They are red because they contain a protein called haemoglobin which carries oxygen round the body

8.

Which of the following is involved in reproduction?

[ ]	Neuron cells
[ ]	Red blood cells
[ ]	Root hair cells

These have a 'tail' that allows them to swim towards an ovum (egg)

9.

Which of the following receives, carries and passes on electrical impulses?
