Cell Biology Worksheet: Labeling Parts of Animal and Plant Cells and Their Functions

Task Overview:

The task involves labeling the parts of an animal cell and a plant cell, as well as completing a table that describes the functions of these cell parts. Additionally, you are asked to shade in green the structures that are only found in plant cells.

Step 1: Labeling the Cell Parts

#### Animal Cell (Left Diagram)
1. Nucleus: The large, dark circle in the center.
2. Cell Membrane: The outer boundary of the cell.
3. Mitochondrion: The small, oval-shaped structure near the nucleus.
4. Ribosome: The tiny dots scattered within the cell.

#### Plant Cell (Right Diagram)
1. Nucleus: The large, dark circle in the center.
2. Cell Wall: The outermost layer surrounding the cell membrane.
3. Chloroplasts: The green, oval-shaped structures scattered throughout the cell.
4. Vacuole: The large, central sac-like structure.
5. Cell Membrane: The inner boundary just inside the cell wall.
6. Cytoplasm: The gel-like substance filling the cell.
7. Mitochondria: The small, oval-shaped structures scattered throughout the cell.

Step 2: Completing the Table of Cell Part Functions

| Cell Structure | Function (job) |
|---------------------------|-------------------------------------------------------------------------------------|
| Nucleus | Contains genetic material (DNA) and controls cell activities. |
| Cytoplasm | Fluid medium where most cellular activities occur; supports organelles. |
| Cell surface membrane | Regulates what enters and exits the cell; maintains internal environment. |
| Mitochondria | Produces energy for the cell through cellular respiration. |
| Cell wall | Provides structural support and protection (only in plant cells). |
| Chloroplast | Site of photosynthesis; converts light energy into chemical energy (only in plant cells). |
| Vacuole | Stores nutrients, waste products, and water; helps maintain turgor pressure (larger in plant cells). |

Step 3: Shading Structures Found Only in Plant Cells

The structures that are only found in plant cells are:
- Cell wall
- Chloroplasts
- Large vacuole

These should be shaded in green in the table.

3. Mitochondrion
4. Ribosome

#### Labels for Plant Cell:
1. Nucleus
2. Cell Wall
3. Chloroplasts
4. Vacuole
5. Cell Membrane
6. Cytoplasm
7. Mitochondria

#### Completed Table:
| Cell Structure | Function (job) |
|---------------------------|-------------------------------------------------------------------------------------|
| Nucleus | Contains genetic material (DNA) and controls cell activities. |
| Cytoplasm | Fluid medium where most cellular activities occur; supports organelles. |
| Cell surface membrane | Regulates what enters and exits the cell; maintains internal environment. |
| Mitochondria | Produces energy for the cell through cellular respiration. |
| Cell wall | Provides structural support and protection (only in plant cells). |
