1. Label the organelles in the plant and animal cells

We are given a list of organelles:

- Mitochondria
- Large Vacuole
- Small Vacuole
- Cytoplasm
- Cell Membrane
- Nucleus
- Chloroplasts
- Cell Wall

Now, let’s identify and label each structure in the two diagrams.

#### Picture 1 (Left – Plant Cell):
This cell has a rectangular shape, cell wall, large central vacuole, and green chloroplasts.

Labeling from the arrows (top to bottom, left to right):

1. Top-left arrow → Chloroplasts (green oval structures)
2. Top-center arrow → Nucleus (purple round structure with a darker spot inside)
3. Top-right arrow → Cell Wall (outer green rigid layer)
4. Middle-left arrow → Mitochondria (small red/orange bean-shaped structures)
5. Middle-center arrow → Large Vacuole (large blue central structure)
6. Middle-right arrow → Cytoplasm (light blue area surrounding organelles)
7. Bottom-left arrow → Chloroplasts (another green structure)
8. Bottom-center arrow → Cell Membrane (inner boundary just inside the cell wall)
9. Bottom-right arrow → Mitochondria (another red/orange structure)

> Note: The cytoplasm is the gel-like substance filling the cell, so it surrounds all organelles. The cell membrane is just inside the cell wall.

#### Picture 2 (Right – Animal Cell):
This cell is round, lacks a cell wall and chloroplasts, and has smaller vacuoles.

Labeling:

1. Top-left arrow → Small Vacuole (small light blue circle)
2. Top-center arrow → Nucleus (central dark red structure)
3. Top-right arrow → Cytoplasm (pink background)
4. Middle-left arrow → Mitochondria (red/orange bean-shaped)
5. Middle-center arrow → Cell Membrane (outer pink boundary)
6. Middle-right arrow → Small Vacuole (another small light blue circle)
7. Bottom-left arrow → Mitochondria (another one)
8. Bottom-right arrow → Mitochondria (last one)

> Note: Animal cells have no cell wall or chloroplasts. They may have small vacuoles, but not a large central one.

2. The type of cell in picture 1 is:

✔ Plant cell

> Reason: It has a cell wall, large central vacuole, and chloroplasts — all unique to plant cells.

---

3. The type of cell in picture 2 is:

✔ Animal cell

> Reason: It lacks a cell wall and chloroplasts, has a flexible cell membrane, and contains small vacuoles — typical of animal cells.

4. List the organelles that are only found in PLANT cells.

✔ Organelles only found in plant cells:

1. Cell Wall
2. Chloroplasts
3. Large Central Vacuole

> Explanation:
- Cell Wall: Provides structural support; found in plants, fungi, and some bacteria, but not in animals.
- Chloroplasts: Site of photosynthesis; only in plant cells and some protists.
- Large Central Vacuole: Stores water, ions, and waste; helps maintain turgor pressure; much larger than in animal cells.

> Note: While vacuoles exist in both, large central vacuole is characteristic of plant cells. Animal cells have small vacuoles.

- Bottom-right: Mitochondria

2. Picture 1: Plant cell
3. Picture 2: Animal cell
4. Organelles only in plant cells: Cell Wall, Chloroplasts, Large Central Vacuole
