Parts of a plant cell and what they do
| Part | What it does | In plant cells | In animal cells |
|---|---|---|---|
| Cell wall | A stiff outer layer made mostly of cellulose. It supports and protects the cell, gives it a fixed shape and stops it from bursting when it takes in water. | yes | no |
| Cell membrane | A thin, flexible layer of lipids and proteins around the cell. It controls what goes into and out of the cell. | yes (just inside the cell wall) | yes (the outer edge) |
| Cytoplasm | The jelly-like fluid that fills the cell and holds the organelles in place. Many of the cell’s chemical reactions happen here. | yes | yes |
| Nucleus | The control centre of the cell. It holds the cell’s DNA inside a double membrane called the nuclear envelope and controls growth and cell division. | yes | yes |
| Nucleolus | A dense spot inside the nucleus where the parts of ribosomes are made. | yes | yes |
| Central vacuole | A large sac of water and dissolved substances (cell sap) that can fill most of a plant cell. It stores water and pushes on the cell wall to keep the plant firm. | yes (one large one) | no (only small vacuoles) |
| Chloroplast | Green organelles where photosynthesis happens. Their chlorophyll captures light energy to make sugar from carbon dioxide and water, giving off oxygen. | yes | no |
| Mitochondrion | The powerhouse of the cell. Through cellular respiration it releases energy from food (glucose) and stores it as ATP that the cell can use. | yes | yes |
| Rough endoplasmic reticulum | Folded membranes covered in ribosomes, joined to the nucleus. It makes and folds proteins, which are then sent on to the Golgi apparatus. | yes | yes |
| Smooth endoplasmic reticulum | Tube-like membranes with no ribosomes. It makes lipids (fats), stores calcium and helps break down harmful substances. | yes | yes |
| Golgi apparatus | A stack of flat, curved sacs. It changes, sorts and packs proteins and lipids into small bubbles called vesicles and sends them where they are needed. | yes | yes |
| Ribosomes | Tiny structures made of RNA and protein that build proteins. Some float free in the cytoplasm and some sit on the rough ER. | yes | yes |
| Lysosome | Small sacs full of digestive enzymes. They break down worn-out cell parts, food particles and bacteria. | rarely (the vacuole does this job) | yes |
| Centrioles | A pair of short tubes made of microtubules, set at right angles near the nucleus. They help organise the fibres that pull chromosomes apart when the cell divides. | no (most plant cells) | yes |
| Vacuole | Small sacs that store water, food or waste. Animal cells have several small vacuoles; a plant cell has one large central vacuole. | one large central vacuole | yes (small) |
Plant cell vs animal cell
| Feature | Plant cell | Animal cell |
|---|---|---|
| Shape | Fixed, often like a box or brick | Round or irregular, can change shape |
| Cell wall | Yes, made of cellulose | No |
| Cell membrane | Yes, just inside the cell wall | Yes, it is the outer layer |
| Chloroplasts | Yes, for photosynthesis | No |
| Vacuole | One large central vacuole | Several small vacuoles, or none |
| Centrioles | No (in most plant cells) | Yes |
| Lysosomes | Rare | Yes |
| How it gets food | Makes its own sugar by photosynthesis | Takes in food from outside |
| Shared parts | Nucleus, cytoplasm, mitochondria, ER, Golgi, ribosomes | Nucleus, cytoplasm, mitochondria, ER, Golgi, ribosomes |

Make it for your school project
A plant cell model is easy to recognise when it has a box shape, a thick cell wall, one big vacuole and plenty of green chloroplasts. A shoebox or a clear plastic box works well for the box shape.
- Pick a base for the cytoplasm: clear gelatin in a bowl, a foam ball cut in half, modelling clay, or a shoebox.
- Make each part in its own colour. The colours in the 3D model above are a good guide, and the parts table lists cheap materials for each one.
- Place the parts where they sit in the model. Turn the model and use the Explode slider to see what is behind what.
- Label every part with a toothpick flag or a numbered key, and add one line saying what it does. Print our labeled diagram as your key, or the blank one to fill in yourself.
Tip: Put the big vacuole in the middle and push the nucleus to one side, as in a real plant cell.
Materials for each part
- Cell wall: shoebox, cardboard or a thick green outline
- Cell membrane: plastic wrap, a balloon skin or a thin ribbon
- Cytoplasm: clear gelatin, clay or foam
- Nucleus: a ping-pong ball, plum or large bead
- Nucleolus: a small dark bead or marble inside the nucleus
- Central vacuole: a small water balloon or a bag of clear gel
- Chloroplast: green beans, lentils or green jelly beans
- Mitochondrion: beans, macaroni or red jelly sweets
- Rough ER: folded ribbon or wavy pipe cleaners dotted with seeds
- Smooth ER: smooth yarn or gummy worms
- Golgi apparatus: stacked curved strips of paper or a few stacked pasta shells
- Ribosomes: sprinkles, peppercorns or small seeds
