Cell Labeling Worksheet

This cell labeling worksheet generator makes printable worksheets for animal cells, plant cells, or both side by side. It runs in your web browser, is free, and needs no sign-up. You tick the activities and options you want, and the printable pages update as you go.

Each worksheet includes a labeled cell diagram with numbered boxes, plus fill-in-the-blank and vocabulary matching activities. The wording fits about grades 5 to 8. You can add a word bank, an answer key, or black line art for coloring. Nothing you create is uploaded or sent to a server, and you can download the result as a PDF or print it directly.

How to make a cell labeling worksheet

1. Open the Worksheet menu and choose Animal cell (the default), Plant cell, or Plant and animal cells.
2. Tick the activities you want. Label the diagram, Fill in the blanks, and Vocabulary matching are on by default. Labeled picture to color gives a fully labeled diagram to study from.
3. Set the Word bank on or off. Turning it off makes the sheet harder.
4. Choose the number of Items per activity: 4, 6, 8, 10, or 12.
5. Turn Color pictures on for soft colors, or off for black line art that saves ink.
6. Turn on Name and date line, and edit the Worksheet title if you want a different heading.
7. Turn on Answer key pages to add pages with the answers filled in.
8. Choose US Letter or A4 as the paper size.
9. Click New version to shuffle the word bank, matching letters, and order, so each student or class can get a different version.
10. Click Download PDF for a sharp file that prints at true size, or click Print to open the print dialog with only the worksheet pages.

Copy link copies a link that reopens the same worksheet, including the current version, so you can return to it or share it.

What are the parts of an animal cell?

An animal cell has a cell membrane, cytoplasm, and a nucleus, with smaller structures called organelles inside. The worksheet labels ten parts of an animal cell.

• Nucleus: the control center of the cell, which holds DNA.
• Nucleolus: a small dark spot inside the nucleus that makes ribosomes.
• Cell membrane: controls what goes into and out of the cell.
• Cytoplasm: a jelly-like fluid that the organelles float in.
• Mitochondria: release energy from food (cellular respiration).
• Ribosomes: make proteins.
• Endoplasmic reticulum: moves materials around the cell.
• Golgi apparatus: packages proteins and ships them out.
• Lysosome: breaks down waste and worn-out parts.
• Vacuole: stores water, food, and waste.

What is the difference between a plant cell and an animal cell?

A plant cell has a cell wall, chloroplasts, and a large central vacuole, while an animal cell does not. Both cell types share the nucleus, cell membrane, cytoplasm, mitochondria, ribosomes, endoplasmic reticulum, and Golgi apparatus.

Plant cells are usually box-shaped because of the stiff cell wall. Animal cells are rounder and more irregular. The Plant and animal cells worksheet asks students to sort parts into “plant cells only” (cell wall, chloroplasts, large central vacuole) and “animal and plant cells” (the shared parts).

What do mitochondria and chloroplasts do?

Mitochondria release energy from food through cellular respiration. They are found in both animal and plant cells.

Chloroplasts make food by photosynthesis and hold the green pigment chlorophyll. They are found only in plant cells, which is why they appear on the plant cell sheet and not on the animal cell sheet.

What is the difference between the cell membrane and the cell wall?

Every cell has a cell membrane: a thin, flexible layer that controls what goes into and out of the cell. Only plant cells (and some other organisms) also have a cell wall, a stiff layer outside the membrane that supports and protects the cell and gives it a boxy shape. On the plant cell sheet both are labeled, so students can see the wall as the outer line and the membrane just inside it.

Frequently asked questions

Is there an answer key?

Yes. Turn on Answer key pages to add pages with every answer filled in, shown in blue. Labeled picture to color also shows every label filled in, which works well for study.

Which grades is it for?

The wording fits about grades 5 to 8. You can adjust difficulty by turning the word bank off or changing the number of items per activity.

Can I get a blank animal cell diagram?

The Label the diagram activity shows an animal cell picture with numbered empty boxes and leader lines for students to fill in. Turn Color pictures off to get black line art that is easy to print and color.

Does it cost anything or need an account?

No. The tool is free, needs no sign-up, and runs in your browser. Nothing is uploaded or sent to a server.

Can I make a different version for each student?

Yes. Click New version to shuffle the word bank, matching letters, and order. The version is kept in the link, so you can reopen the same one later.

Why are mitochondria called the powerhouse of the cell?

Mitochondria release the energy stored in food through cellular respiration, and the cell uses that energy to do its work. That is why they are often called the powerhouse of the cell. Both animal and plant cells have mitochondria; plant cells also have chloroplasts, which make the food in the first place.
