Worksheet Analysis

The worksheet lists 17 functions of cell organelles and asks you to match them with the correct cell part (organelle). Each function describes what the organelle does within the cell. Your task is to identify the organelle responsible for each function.

---

Solution Approach

1. Understand Each Function: Carefully read each function to determine what process or structure it describes.
2. Recall Cell Organelle Functions: Use your knowledge of cell biology to match each function with the appropriate organelle.
3. Check for Clues: Some functions may include keywords that directly hint at the organelle's name (e.g., "stores materials" → Vacuole).

Correct Matches

Here are the correct matches for each function:

1. Stores materials within the cell
- Vacuole

2. Closely stacked, flattened sacs (plants only)
- Chloroplast

3. The site of protein synthesis
- Ribosome

4. Transports materials within the cell
- Endoplasmic Reticulum

5. Jelly-like substance in the cell
- Cytoplasm

6. Organelles that control all activities of the cell
- Nucleus

7. Contains chlorophyll, a green pigment that traps energy from sunlight
- Chloroplast

8. Exports excess or worn out cell parts, food particles, and invading viruses or bacteria
- Lysosome/Peroxisome

9. Small tube-like structures located on the surface of the endoplasmic reticulum
- Rough Endoplasmic Reticulum

10. Provides temporary storage of food, enzymes, and water
- Vesicle

11. Firm, protective structure that gives the cell its shape in plants, fungi, most bacteria, and some protists
- Cell Wall

12. Produces usable forms of energy for the cell
- Mitochondrion

13. Packages proteins for transport out of the cell
- Golgi Apparatus

14. Produces lipids
- Smooth Endoplasmic Reticulum

15. Site where ribosomes are made
- Nucleolus

16. The network surrounding the cell
- Plasma Membrane

17. Provides support for the cell
- Cytoskeleton

Explanation of Key Organelles

- Vacuole: Stores nutrients, waste products, and water.
- Chloroplast: Site of photosynthesis in plant cells; contains chlorophyll.
- Ribosome: Synthesizes proteins.
- Endoplasmic Reticulum (ER): Transport system within the cell; rough ER has ribosomes, while smooth ER produces lipids.
- Cytoplasm: Gel-like substance inside the cell membrane.
- Nucleus: Control center of the cell; contains DNA.
- Lysosome/Peroxisome: Break down waste materials and cellular debris.
- Vesicle: Small sacs that transport materials within the cell.
- Cell Wall: Rigid outer layer in plant cells, providing structural support.
- Mitochondrion: Powerhouse of the cell; produces ATP (energy).
- Golgi Apparatus: Modifies, sorts, and packages proteins for secretion.
- Nucleolus: Region within the nucleus where ribosomes are assembled.
- Plasma Membrane: Regulates the movement of substances in and out of the cell.
- Cytoskeleton: Network of protein filaments that maintains cell shape and aids in movement.
