Printable worksheet designed to help biology students identify and understand the functions of various cell organelles.

Let’s go step by step to fill in the table correctly.

We are matching cell organelles with their functions and where they’re found (in plant cells, animal cells, or both).

Here’s what each organelle does and where it’s located:

1. Cell – This is not an organelle; it’s the whole unit. But since it’s listed, we’ll note:
- Function: Basic unit of life
- Found in: Both plant and animal cells

2. Cell Wall – Gives structure and protection
- Function: Supports and protects the cell
- Found in: Plant cells only (not in animal cells)

3. Cytoplasm – Jelly-like substance inside the cell
- Function: Holds organelles in place and helps move materials around
- Found in: Both plant and animal cells

4. Mitochondria – Powerhouse of the cell
- Function: Makes energy (ATP) for the cell
- Found in: Both plant and animal cells

5. Lysosomes – Digestive system of the cell
- Function: Breaks down waste and old parts
- Found in: Mostly animal cells (some plant cells have them too, but usually we say animal cells for simplicity at this level)

6. Vacuoles – Storage sacs
- Function: Stores water, food, waste
- Found in: Both — but large central vacuole is in plant cells; small ones in animal cells

7. Golgi Bodies – Packaging center
- Function: Modifies, sorts, and ships proteins
- Found in: Both plant and animal cells

8. Chloroplasts – Where photosynthesis happens
- Function: Uses sunlight to make food (glucose)
- Found in: Plant cells only (and some algae — not in animal cells)

9. Endoplasmic Reticulum (ER) – Transport system
- Function: Moves materials inside the cell; rough ER makes proteins, smooth ER makes lipids
- Found in: Both plant and animal cells

10. Ribosomes – Protein makers
- Function: Builds proteins
- Found in: Both plant and animal cells (even in bacteria!)

11. Nucleus – Control center
- Function: Holds DNA and controls cell activities
- Found in: Both plant and animal cells (except red blood cells in animals, which lose nucleus — but generally we say both)

12. Nucleolus – Inside the nucleus
- Function: Makes ribosomes
- Found in: Both plant and animal cells (wherever there’s a nucleus)

13. Chromatin – DNA + protein mix
- Function: Contains genetic info; becomes chromosomes when dividing
- Found in: Both plant and animal cells (inside nucleus)

Now let’s fill the table clearly:

| Organelle | Function/Description | Plant and/or Animal Cell? |
|-----------------------|-----------------------------------------------|----------------------------|
| Cell | Basic unit of life | Both |
| Cell Wall | Supports and protects the cell | Plant |
| Cytoplasm | Holds organelles; moves materials | Both |
| Mitochondria | Makes energy (ATP) | Both |
| Lysosomes | Breaks down waste | Animal (mostly) |
| Vacuoles | Stores water, food, waste | Both (large in plants) |
| Golgi Bodies | Packages and ships proteins | Both |
| Chloroplasts | Makes food using sunlight (photosynthesis) | Plant |
| Endoplasmic Reticulum | Transports materials; makes proteins/lipids | Both |
| Ribosomes | Builds proteins | Both |
| Nucleus | Controls cell; holds DNA | Both |
| Nucleolus | Makes ribosomes | Both |
| Chromatin | Holds genetic information | Both |

Note: For lysosomes, some textbooks say “animal cells” because plant cells use vacuoles more for digestion. We’ll stick with “Animal” for simplicity unless your teacher says otherwise.

Final Answer:
The completed table should look like this:

| Organelle | Function/Description | Plant and/or Animal Cell? |
|-----------------------|-----------------------------------------------|----------------------------|
| Cell | Basic unit of life | Both |
| Cell Wall | Supports and protects the cell | Plant |
| Cytoplasm | Holds organelles; moves materials | Both |
| Mitochondria | Makes energy (ATP) | Both |
| Lysosomes | Breaks down waste | Animal |
| Vacuoles | Stores water, food, waste | Both |
| Golgi Bodies | Packages and ships proteins | Both |
| Chloroplasts | Makes food using sunlight | Plant |
| Endoplasmic Reticulum | Transports materials; makes proteins/lipids | Both |
| Ribosomes | Builds proteins | Both |
| Nucleus | Controls cell; holds DNA | Both |

| Chromatin | Holds genetic information | Both |
