Let's solve the problem step by step using the image and the instructions provided.

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 both diagrams.

#### Plant Cell (Left Diagram):
- Green outer layer → Cell Wall
- Thin inner line inside cell wall → Cell Membrane
- Large blue structure in center → Large Vacuole
- Green oval structures → Chloroplasts
- Red oval with dark dot inside → Nucleus
- Orange oval structures → Mitochondria
- Pink stacked structures → Golgi apparatus (not listed, so skip)
- Blue background area → Cytoplasm
- Small green dots → Ribosomes (not listed, skip)

So, labeling from the arrows:
- Arrow pointing to outermost green layer → Cell Wall
- Arrow pointing to inner membrane → Cell Membrane
- Arrow pointing to large blue structure → Large Vacuole
- Arrow pointing to green oval shapes → Chloroplasts
- Arrow pointing to nucleus → Nucleus
- Arrow pointing to orange oval shapes → Mitochondria
- Arrow pointing to cytoplasmic region → Cytoplasm

#### Animal Cell (Right Diagram):
- Outer pink boundary → Cell Membrane
- No cell wall
- Small light blue circles → Small Vacuole
- Red nucleus with green interior → Nucleus
- Orange oval shapes → Mitochondria
- Blue network → Endoplasmic Reticulum (not listed, skip)
- Green oval shapes → Mitochondria? No — wait: these are likely mitochondria or lysosomes. But only mitochondria is listed.
Actually, the green ovals in the animal cell are mitochondria, same as in plant cell.
- Cytoplasm → the pink area
- Small vacuoles → small blue circles

So, labeling:
- Outer boundary → Cell Membrane
- Small blue circles → Small Vacuole
- Central red structure → Nucleus
- Green oval shapes → Mitochondria
- Pink background → Cytoplasm

> Note: Chloroplasts and Cell Wall are only in plant cells, so they do not appear in the animal cell.

2. The type of cell in picture 1 is:

→ Plant cell

Reason: It has a cell wall, large central vacuole, and chloroplasts, which are unique to plant cells.

---

3. The type of cell in picture 2 is:

→ Animal cell

Reason: It lacks a cell wall, has small vacuoles, and no chloroplasts. It has a flexible cell membrane and other typical animal cell features.

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

From the list provided and our knowledge:

- Cell Wall
- Chloroplasts
- Large Vacuole (Note: Animal cells have small vacuoles, but plant cells have one large central vacuole)

> While "Large Vacuole" is not *exclusively* unique (some animal cells can have large vacuoles), in standard biology education, it is considered a defining feature of plant cells.

So, the organelles only found in plant cells are:

✔ Cell Wall
✔ Chloroplasts
✔ Large Vacuole

> Note: Some sources may say "large central vacuole" is characteristic of plant cells, even if not exclusive.

✔ Final Answers:

#### 1. Labels (based on arrows):

Plant Cell (Left):
- Top left arrow → Chloroplasts
- Left side arrow → Mitochondria
- Middle top → Nucleus
- Right side arrow → Mitochondria
- Bottom right arrow → Cytoplasm
- Bottom arrow → Large Vacuole
- Top right arrow → Cell Wall
- Inner edge → Cell Membrane

Animal Cell (Right):
- Top left arrow → Small Vacuole
- Top right arrow → Cytoplasm
- Middle arrow → Nucleus
- Bottom left arrow → Mitochondria
- Bottom right arrow → Mitochondria
- Outer boundary → Cell Membrane

(You would write these labels next to the arrows.)
