Plant and animal cells labeling | TPT - Free Printable

Let’s go step by step to identify each organelle in the plant cell diagram using the color code provided.

We’ll match each labeled part of the cell with its correct name and assigned color. Since this is a coloring worksheet, we’re not calculating numbers — we’re matching shapes and positions to their names based on standard plant cell structure.

Here’s how to do it:

1. Cell Wall – This is the outermost thick layer surrounding the whole cell. It gives the plant cell its rigid shape. → Color: dark green

2. Cell Membrane – Just inside the cell wall, this is a thinner line that wraps around the cytoplasm. → Color: yellow

3. Cytoplasm – The jelly-like substance filling the space between the membrane and the organelles. It’s everything inside except the big central vacuole and nucleus. → Color: beige

4. Central Vacuole – The very large empty-looking space in the middle of the cell. In plants, it takes up most of the room. → Color: light blue

5. Nucleus – The round structure near the top right (usually), contains genetic material. Inside it is a smaller circle called the nucleolus. → Color: light pink

6. Nucleolus – The small dot inside the nucleus. → Color: dark pink

7. Mitochondria – Oval-shaped with wavy lines inside (like folded paper). There are several scattered around. → Color: red

8. Chloroplasts – Also oval, but with stacked discs inside (like pancakes). These are only in plant cells and make food using sunlight. → Color: light green

9. Rough Endoplasmic Reticulum (RER) – Looks like folded sheets or maze with dots (ribosomes) on them. Usually near the nucleus. → Color: violet

10. Smooth Endoplasmic Reticulum (SER) – Similar folded shape but NO dots. Often next to RER. → Color: light purple

11. Golgi Apparatus – Stack of curved flat sacs (like pancakes again, but smoother). Often near the ER. → Color: orange

12. Golgi Vesicles – Small circles near the Golgi apparatus. They carry materials away from it. → Color: gray

13. Ribosomes – Tiny dots. Some float freely in cytoplasm, some stick to RER. → Color: dark brown

14. Peroxisome – Small round organelles, often shown as simple circles without internal detail. → Color: dark blue

15. Cytoskeleton – Thin thread-like lines running through the cytoplasm. Helps hold things in place. → Color: maroon

Now, let’s double-check our matches against common plant cell diagrams:

- Cell wall = outer boundary ✔
- Central vacuole = biggest space ✔
- Nucleus = control center with nucleolus inside ✔
- Chloroplasts = have stacks (thylakoids) ✔
- Mitochondria = have inner folds (cristae) ✔
- ER types = rough has dots, smooth doesn’t ✔
- Golgi = stacked cisternae ✔
- Ribosomes = tiny dots ✔
- Peroxisomes = small spheres ✔
- Cytoskeleton = thin fibers ✔

All match correctly.

Final Answer:
To complete the worksheet, color each organelle according to this key:

- Cytoplasm → beige
- Central vacuole → light blue
- Cell membrane → yellow
- Mitochondria → red
- Cytoskeleton → maroon
- Rough endoplasmic reticulum → violet
- Smooth endoplasmic reticulum → light purple
- Chloroplast → light green
- Ribosome → dark brown
- Peroxisome → dark blue
- Cell wall → dark green
- Nucleolus → dark pink
- Nucleus → light pink
- Golgi apparatus → orange
- Golgi vesicles → gray

Color each part in the diagram accordingly to correctly identify all organelles.
