The Plant Cell worksheet with labeled parts and a table for matching organelles to their functions.

Let’s solve this step by step.

We are given a diagram of a plant cell with letters A through L pointing to different parts. We also have a table listing organelles, and we need to:

1. Match each organelle to the correct letter in the diagram.
2. Write the function (purpose) of each organelle.

First, let’s recall what each part of a plant cell does — and then match it to the diagram based on typical plant cell diagrams.

Step 1: Identify each labeled part in the diagram

Looking at standard plant cell diagrams:

- A → Usually points to the outermost layer → Cell wall
- B → Just inside the cell wall → Cell membrane (plasma membrane)
- C → Small dots floating in cytoplasm → Ribosomes
- D → Green oval structures → Chloroplasts
- E → Bean-shaped with inner folds → Mitochondria
- F → Fluid filling the cell → Cytoplasm
- G → Large central sac → Vacuole
- H → Stack of flattened sacs → Golgi complex
- I → Network of tubes near nucleus → Rough endoplasmic reticulum (has ribosomes)
- J → Dark spot inside nucleus → Nucleolus
- K → Round structure holding DNA → Nucleus
- L → Smooth tubes without ribosomes → Smooth endoplasmic reticulum

*(Note: In some diagrams, labels may vary slightly, but this is the most common labeling for educational worksheets like this one.)*

Step 2: Fill in the “Diagram location (Letter)” column

Now match each organelle from the table to its letter:

| Organelle | Diagram Location (Letter) |
|----------------------------|---------------------------|
| cell (plasma) membrane | B |
| cell wall | A |
| cytoplasm | F |
| golgi complex | H |
| chloroplast | D |
| mitochondria | E |
| nucleus | K |
| nucleolus | J |
| ribosome | C |
| rough endoplasmic reticulum| I |
| smooth endoplasmic reticulum| L |
| vacuole | G |

Step 3: Write the function of each organelle

Let’s write simple, clear functions for each:

- cell (plasma) membrane: Controls what enters and leaves the cell.
- cell wall: Gives the plant cell shape and support; protects the cell.
- cytoplasm: Jelly-like substance where organelles float and chemical reactions happen.
- golgi complex: Packages and ships proteins and other materials out of the cell.
- chloroplast: Makes food for the plant using sunlight (photosynthesis).
- mitochondria: Produces energy (ATP) for the cell — the “powerhouse”.
- nucleus: Holds the cell’s DNA and controls all cell activities.
- nucleolus: Makes ribosomes inside the nucleus.
- ribosome: Builds proteins for the cell.
- rough endoplasmic reticulum: Has ribosomes attached; helps make and transport proteins.
- smooth endoplasmic reticulum: Makes lipids (fats) and detoxifies chemicals; no ribosomes.
- vacuole: Stores water, nutrients, and waste; large in plant cells to keep them firm.

✔ Now we can fill in the entire table correctly.

Final Answer:

| Organelle | Diagram Location (Letter) | Function |
|----------------------------|---------------------------|--------------------------------------------------------------------------|
| cell (plasma) membrane | B | Controls what enters and leaves the cell |
| cell wall | A | Provides structure and protection |
| cytoplasm | F | Gel-like fluid where organelles are suspended and reactions occur |
| golgi complex | H | Modifies, sorts, and packages proteins for secretion |
| chloroplast | D | Performs photosynthesis to make food using sunlight |
| mitochondria | E | Produces energy (ATP) for the cell |
| nucleus | K | Contains DNA and controls cell activities |
| nucleolus | J | Makes ribosomes |
| ribosome | C | Builds proteins |
| rough endoplasmic reticulum| I | Synthesizes and transports proteins (has ribosomes) |
| smooth endoplasmic reticulum| L | Synthesizes lipids and detoxifies substances |
| vacuole | G | Stores water, ions, nutrients, and waste; maintains turgor pressure |
