Label the Parts of the Plant and Animal Cell - Free Printable

Let’s work through this step by step.

This worksheet is about labeling parts of animal and plant cells. Each numbered part in the diagrams corresponds to a specific organelle or structure inside the cell. We need to match each number with the correct name.

We’ll go one diagram at a time — first the Animal Cell, then the Plant Cell.

Animal Cell Labeling (Top Diagram)

Looking at standard animal cell diagrams:

1. Centrioles – often shown as paired cylindrical structures near the nucleus.
2. Lysosome – small vesicle that breaks down waste.
3. Golgi Apparatus – stacked membranes that package proteins.
4. Nucleus – large central control center with nucleolus inside.
5. Nucleolus – dark spot inside nucleus where ribosomes are made.
6. Rough Endoplasmic Reticulum (RER) – has dots (ribosomes) on it, makes proteins.
7. Smooth Endoplasmic Reticulum (SER) – no dots, makes lipids.
8. Cell Membrane – outer boundary of the cell.
9. Mitochondrion – power plant of the cell, oval with inner folds.
10. Cytoplasm – jelly-like substance filling the cell.
11. Vacuole – small storage bubble (smaller than in plant cells).
12. Ribosome – tiny dots making proteins (can be free or on RER).
13. Cytoskeleton – network of fibers holding shape (sometimes not clearly labeled).
14. Microvilli – finger-like projections on surface (if shown).

Wait — let’s double-check based on common textbook labels for this exact diagram style.

Actually, looking again at typical versions of this worksheet:

In many standard “Cell Labeling - Animal Cell” worksheets:

1. Centrioles
2. Lysosome
3. Golgi Apparatus
4. Nucleus
5. Nucleolus
6. Rough ER
7. Smooth ER
8. Cell Membrane
9. Mitochondrion
10. Cytoplasm
11. Vacuole
12. Ribosome
13. Cytoskeleton / Microfilaments
14. Microvilli (or sometimes just “cell surface”)

But since we don’t have the actual image to point to, we must rely on standard labeling conventions used in schools.

Similarly for Plant Cell:

Plant Cell Labeling (Bottom Diagram)

Standard plant cell parts:

1. Cell Wall – rigid outer layer
2. Cell Membrane – inside cell wall
3. Chloroplast – green, makes food via photosynthesis
4. Vacuole – huge central storage sac
5. Cytoplasm – fluid inside
6. Nucleus – control center
7. Nucleolus – inside nucleus
8. Nuclear Envelope – membrane around nucleus
9. Rough ER – with ribosomes
10. Smooth ER – without ribosomes
11. Golgi Apparatus – packages materials
12. Mitochondrion – energy producer
13. Ribosome – protein maker
14. Vesicle – small transport bubble

Again, matching to common worksheet keys.

Since this is a standard educational worksheet, here’s the most likely correct answer key based on widely used versions:
