Animal cell diagram with numbered labels and a table to identify cell parts and their functions.

Let's solve this step by step.

Step 1: Label the Animal Cell Diagram

We are given a diagram of an animal cell with numbered parts (1–11). Based on typical animal cell structure and the note that "lysosomes are oval and vacuoles are more rounded," we can identify each part.

Here’s the identification:

1. Mitochondrion – These are bean-shaped structures with folds (cristae) inside; they are energy-producing organelles.
2. Ribosome – Small dots, often seen attached to the endoplasmic reticulum or free in the cytoplasm.
3. Centriole – A pair of short, cylindrical structures near the nucleus; involved in cell division.
4. Lysosome – Small, oval-shaped vesicles (as noted in the hint).
5. Vacuole – Rounded, fluid-filled sacs; in animal cells, these are smaller than in plant cells.
6. Golgi body (or Golgi apparatus) – Stack of flattened sacs, often near the nucleus.
7. Nuclear envelope (nuclear membrane) – The double membrane surrounding the nucleus.
8. Endoplasmic reticulum (ER) – Network of membranes; rough ER has ribosomes attached, smooth ER does not.
9. Nucleolus – Dense sphere within the nucleus; site of ribosome synthesis.
10. Nucleus – Central large structure containing genetic material.
11. Cell membrane – Outer boundary of the cell; controls movement of substances in and out.

So, labeling:

- 1. Mitochondria
- 2. Ribosome
- 3. Centriole
- 4. Lysosome
- 5. Vacuole
- 6. Golgi body
- 7. Nuclear envelope
- 8. Endoplasmic reticulum
- 9. Nucleolus
- 10. Nucleus
- 11. Cell membrane

Step 2: Fill in the Function Table

Now, complete the table for the listed cell parts.

| Cell Part | Function of Cell Part |
|----------|------------------------|
| 12. nucleus | Controls cell activities; stores DNA and directs protein synthesis |
| 13. endoplasmic reticulum | Transports materials within the cell; rough ER makes proteins, smooth ER synthesizes lipids and detoxifies chemicals |
| 14. ribosome | Site of protein synthesis |
| 15. cytoplasm | Gel-like substance that holds organelles in place; site of many metabolic reactions |
| 16. nucleolus | Produces ribosomal subunits (ribosomes) |
| 17. Golgi body | Modifies, sorts, and packages proteins and lipids for transport |
| 18. cell membrane | Regulates what enters and exits the cell; maintains homeostasis |
| 19. cytoskeleton | Provides structural support, helps maintain cell shape, and aids in movement and transport |
| 20. lysosome | Breaks down waste materials and cellular debris; contains digestive enzymes |
| 21. mitochondria | Produces energy (ATP) through cellular respiration |
| 22. vacuole | Stores water, ions, nutrients, and waste products; helps maintain osmotic balance |
