Free Year 9 Specialised Cells, Tissues and Organs Worksheet
Students match specialised plant and animal cells, such as red blood cells, nerve cells, sperm cells, root hair cells and guard cells, to their features and functions. They order the levels of organisation from cell to tissue, organ, organ system and organism, convert between millimetres and micrometres, and calculate real cell sizes from microscope images using magnification.

How to use this worksheet
- Print the PDF or complete it on screen. Write the student's name and date at the top.
- Read the instructions for each part together before starting. Encourage working to be shown.
- Mark with the answer sheet. Use the model answers and success criteria as a guide rather than a single right answer.
- Record the score, celebrate what went well, then follow the "What's next" suggestion.
Common questions
Who is this worksheet for?
Year 9 students (typically ages 13–14) working on cells & classification. It is pitched at level 2 · standard.
Are the answers included?
Yes. The PDF includes a full answer sheet with model answers and success criteria where there is more than one good answer. You can also view the answers online.

Remember: structure is linked to function. Always say how a feature helps the cell do its job.
Part A: Specialised cells
In a multicellular organism, cells are specialised: each type has a shape and set of structures suited to one job. This is called cell specialisation or differentiation.
For example, a nerve cell is long and thin so it can carry signals over long distances, and a root hair cell has a long projection that gives it a large surface area for absorbing water and minerals from the soil.
1.Match each specialised cell to the feature that helps it do its job.
- Red blood cell
- Nerve cell (neuron)
- Sperm cell
- Root hair cell
- Palisade cell (leaf)
- Muscle cell
- No nucleus and a disc shape, leaving more room to carry oxygen
- A tail for swimming and many mitochondria for energy
- Packed with chloroplasts to absorb light for photosynthesis
- A long, thin projection that increases surface area for absorbing water
- Long fibres that can contract, with many mitochondria
- Very long, thin extensions that carry electrical signals
2.Why do root hair cells have no chloroplasts?
- AThey are underground, where there is no light for photosynthesis
- BChloroplasts would make the root too heavy
- CThey use their cell wall to make food instead
- DChloroplasts are found only in animal cells
3.Guard cells are found in pairs on the surface of a leaf. What do they control? (answer space)
4.Explain why a red blood cell having no nucleus is an advantage. (answer space)
Part B: Levels of organisation
Specialised cells are organised into larger structures. Cells of the same type group together to form a tissue. Different tissues work together to form an organ, such as the heart or a leaf. Organs work together in an organ system, such as the digestive system, and all the systems together make up the organism.
5.Write these levels of organisation in order from smallest to largest: organ, cell, organism, organ system, tissue. (answer space)
6.Which of these is an organ?
- AA muscle cell
- BBlood
- CThe stomach
- DThe digestive system
7.A leaf contains several tissues working together to carry out photosynthesis. At which level of organisation is a leaf?
- ACell
- BTissue
- COrgan
- DOrganism
8.A tissue is a group of similar cells working together to perform a particular function. ☐ True ☐ False
9.The heart, blood vessels and blood work together to transport substances around the body. What name is given to a group of organs working together like this? (answer space)
10.Single-celled organisms, such as bacteria, have organs and tissues. ☐ True ☐ False
Part C: How big is a cell?
Cells are measured in micrometres (µm). One micrometre is one thousandth of a millimetre: 1 mm = 1000 µm.
Image size = real size × magnification, so real size = image size ÷ magnification. Make sure both lengths are in the same unit before you divide.
11.Convert 0.1 mm to micrometres.
12.A cheek cell is 60 µm across. Write this length in millimetres.
