Cell Organelles - Worksheet | Distance Learning - Free Printable

Let's complete the table by identifying each organelle based on its shape and function.

Completed Table:

| Name of Organelle | Shape of Organelle | Function of Organelle |
|------------------------|------------------------|----------------------------|
| Ribosome | Small, round (blue dot) | Protein synthesis |
| Endoplasmic Reticulum (ER) | Network of membranes (green wavy structure) | Be smooth (no ribosomes) or rough (with ribosomes) and is associated with packaging, synthesis, and transport of materials in the cell. |
| Golgi Apparatus | Stack of flattened sacs (orange stacked structure) | Processing, packaging, and distribution of molecules |
| Lysosome | Small, spherical vesicle (yellow circle) | Vesicle that contains substances that break down materials. |
| Mitochondrion | Bean-shaped (red oval with folds) | Power plants of cells where energy (ATP) is produced. |
| Vacuole | Large, round (blue circle) | Temporarily stores food, water, waste; rather large in plant cells. |
| Chloroplast | Green, oval with internal stacks (like a stack of pancakes) | Found in plants and is where photosynthesis occurs. |
| Centriole | Two perpendicular cylinders (Y-shaped structure) | Found in animal cells and is used in cell division; the spindle fibers attach to it. |

✔ Explanation:

1. Ribosome
- Shape: Small, spherical (often shown as blue dots).
- Function: Site of protein synthesis.

2. Endoplasmic Reticulum (ER)
- Shape: Network of tubules or sheets (green wavy lines).
- Function: Rough ER has ribosomes; smooth ER does not. Involved in protein/lipid synthesis and transport.

3. Golgi Apparatus
- Shape: Stack of flattened sacs (like orange pancakes).
- Function: Modifies, sorts, and packages proteins and lipids for secretion or delivery.

4. Lysosome
- Shape: Small, round vesicle (yellow sphere).
- Function: Contains digestive enzymes to break down waste materials.

5. Mitochondrion
- Shape: Double membrane, bean-shaped with inner folds (cristae).
- Function: Produces ATP via cellular respiration — the "powerhouse" of the cell.

6. Vacuole
- Shape: Large, round sac (blue circle).
- Function: Stores water, nutrients, and waste; especially large in plant cells.

7. Chloroplast
- Shape: Oval with green color and internal thylakoid stacks (grana).
- Function: Site of photosynthesis in plant cells.

8. Centriole
- Shape: Two cylindrical structures at right angles (Y-shaped).
- Function: Organizes microtubules during cell division; forms spindle fibers in animal cells.
