Let’s go step by step to label the plant cell diagram and fill in the organelle table.

First, we’ll identify each numbered part of the plant cell based on standard biology knowledge:

1. Cell Wall – The outermost rigid layer that gives shape and protection.
2. Cell Membrane – Just inside the cell wall; controls what enters/leaves the cell.
3. Cytoplasm – Jelly-like substance where organelles float.
4. Nucleus – Control center of the cell; contains DNA.
5. Vacuole – Large central sac that stores water, nutrients, waste (very big in plant cells).
6. Chloroplast – Green organelles that make food using sunlight (photosynthesis).
7. Mitochondria – Powerhouse of the cell; makes energy (ATP).
8. Ribosomes – Tiny dots that make proteins (often attached to ER or floating).
9. Endoplasmic Reticulum (ER) – Network of tubes; rough ER has ribosomes, smooth ER doesn’t.
10. Golgi Apparatus – Packages and ships proteins and lipids.

Now let’s match these to the numbers in the diagram (based on typical labeling):

Looking at common plant cell diagrams:

- #1 → Cell Wall
- #2 → Cell Membrane
- #3 → Cytoplasm
- #4 → Nucleus
- #5 → Vacuole (large central one)
- #6 → Chloroplast
- #7 → Mitochondria
- #8 → Ribosome (small dot)
- #9 → Endoplasmic Reticulum
- #10 → Golgi Apparatus

*(Note: Sometimes #8 might be lysosome, but plant cells rarely have them — more likely ribosome. Also, sometimes #9 is ER and #10 is Golgi — this matches standard order.)*

Now for the table: “Organelle” and “Function”

We list each organelle with its main job:

| Organelle | Function |
|-----------------------|-----------------------------------------------|
| Cell Wall | Gives support and protection |
| Cell Membrane | Controls what goes in/out of cell |
| Cytoplasm | Holds organelles; site of many reactions |
| Nucleus | Contains DNA; controls cell activities |
| Vacuole | Stores water, food, waste; helps maintain pressure |
| Chloroplast | Makes food using sunlight (photosynthesis) |
| Mitochondria | Produces energy (ATP) from food |
| Ribosome | Makes proteins |
| Endoplasmic Reticulum | Transports materials; rough ER makes proteins |
| Golgi Apparatus | Modifies, sorts, packages proteins for shipping |

Double-checking: All 10 parts are covered. Functions are simplified for student level.

Final Answer:

Labels for diagram (top to bottom, left to right as per typical layout):

1. Cell Wall
2. Cell Membrane
3. Cytoplasm
4. Nucleus
5. Vacuole
6. Chloroplast
7. Mitochondria
8. Ribosome
9. Endoplasmic Reticulum
10. Golgi Apparatus

Table:

Organelle | Function
----------------------|------------------------------------------
Cell Wall | Support and protection
Cell Membrane | Controls movement in/out of cell
Cytoplasm | Holds organelles; chemical reactions happen here
Nucleus | Controls cell; holds genetic material
Vacuole | Stores water, nutrients, waste
Chloroplast | Makes food using sunlight
Mitochondria | Makes energy for the cell
Ribosome | Builds proteins
Endoplasmic Reticulum | Moves materials; makes proteins/lipids
Golgi Apparatus | Packages and sends out proteins/lipids
