Educational worksheet comparing animal and plant cell structures and functions.

Let’s go step by step to solve this worksheet.

Part 1: Label the cells

We are given two diagrams — one on the left and one on the right.

We need to decide which is a plant cell and which is an animal cell, then label their parts using the word bank:

> Nucleus – mitochondria – cell wall – cell membrane – cytoplasm – chloroplast

---

🔹 Left Diagram (pinkish, round shape):

- It has no rigid outer layer → so no cell wall
- It has small green dots? Wait — actually, looking closely, it does NOT have large green structures like chloroplasts.
- It has a nucleus (big purple thing), mitochondria (brown oval things), cytoplasm (the jelly inside), and a cell membrane (outer boundary).
- This matches an animal cell.

✔ So: “This is animal cell.”

Now label the parts with arrows:

- The big purple circle in the middle → Nucleus
- The brown ovals → Mitochondria
- The outer pink line → Cell membrane
- The jelly-like stuff filling the cell → Cytoplasm
- (No cell wall or chloroplast here — that’s okay!)

---

🔹 Right Diagram (green, boxy shape):

- Has a thick green outer layer → that’s the cell wall
- Has big green oval structures → those are chloroplasts (for photosynthesis)
- Also has nucleus, mitochondria, cytoplasm, and cell membrane (inside the cell wall)
- This is clearly a plant cell

✔ So: “This is plant cell.”

Label the parts:

- Thick green outer edge → Cell wall
- Green ovals inside → Chloroplast
- Big purple center → Nucleus
- Yellowish blobs → Mitochondria
- Outer thin line just inside cell wall → Cell membrane
- Jelly inside → Cytoplasm

Part 2: Match parts to functions

We have these parts:

> NUCLEUS
> MITOCHONDRIA
> CHLOROPLAST
> CELL MEMBRANE
> CELL WALL
> CYTOPLASM

And three statements:

---

📌 Statement 1:
> “This is responsible for controlling what goes in and out of the cell.”

→ That’s the CELL MEMBRANE. It acts like a gatekeeper.

✔ Answer: CELL MEMBRANE

---

📌 Statement 2:
> “It’s where most of reaction take place. It’s also responsible for giving the cell its shape.”

Hmm… “most reactions” happen in the cytoplasm — that’s where chemical reactions occur.

But “giving the cell its shape” — in animal cells, cytoplasm helps, but in plant cells, the cell wall gives shape.

Wait — let’s read again: “It’s where most of reaction take place.” → Definitely cytoplasm.

Then it says: “It’s also responsible for giving the cell its shape.” — In many contexts, especially in basic biology, they say cytoplasm helps maintain shape by filling the cell. But technically, in plants, it’s the cell wall.

Looking at the options — we have both cytoplasm and cell wall.

But note: the statement says “most of reaction take place” — that’s cytoplasm. And while cytoplasm doesn’t give rigid shape, it does help fill and support the cell.

However — wait! Let’s check standard textbook answers.

Actually, in many elementary worksheets:

- “Controls what enters/leaves” → Cell Membrane
- “Where reactions happen + gives shape” → Cytoplasm (sometimes they combine these)
- “Holds all DNA” → Nucleus

But let’s look at the third statement first.

---

📌 Statement 3:
> “This part holds all of the DNA.”

→ That’s definitely the NUCLEUS

✔ Answer: NUCLEUS

---

Back to Statement 2:
If “holds DNA” is nucleus, and “controls entry/exit” is cell membrane, then the remaining function “where reactions happen + gives shape” must be assigned to CYTOPLASM — even though strictly speaking, cell wall gives shape in plants, the worksheet likely expects cytoplasm here because it’s the site of metabolic reactions.

Also, note: the word bank includes “CELL WALL” — but if we assign “gives shape” to cell wall, then what about “where reactions happen”? That wouldn’t fit.

So best match:

- “Where most reactions take place” → CYTOPLASM
- “Gives cell its shape” → In this context, still CYTOPLASM (as it fills and supports)

Some curricula teach that cytoplasm helps maintain shape by turgor pressure in plant cells, but again — for simplicity, we’ll go with:

✔ Statement 2 → CYTOPLASM

Wait — let me double-check.

Actually, re-reading: “It’s where most of reaction take place. It’s also responsible for giving the cell its shape.”

In animal cells, cytoplasm + cytoskeleton gives shape. In plant cells, cell wall gives shape. But since the statement combines both functions, and “reactions happen” is key — cytoplasm is correct.

Alternatively, maybe they mean CELL WALL for shape? But cell wall doesn’t host reactions.

No — reactions happen in cytoplasm.

So final matching:

1. Controls what goes in/out → CELL MEMBRANE
2. Where reactions happen + gives shape → CYTOPLASM
3. Holds all DNA → NUCLEUS

That leaves MITOCHONDRIA, CHLOROPLAST, CELL WALL unused — which is fine, since only 3 blanks.

✔ Final Answers:

Part 1:

Left diagram: This is animal cell.
Label:
- Arrow to purple center → Nucleus
- Arrows to brown ovals → Mitochondria
- Arrow to outer pink line → Cell membrane
- Arrow to jelly inside → Cytoplasm

Right diagram: This is plant cell.
Label:
- Arrow to thick green outer → Cell wall
- Arrow to green ovals → Chloroplast
- Arrow to purple center → Nucleus
- Arrow to yellow blobs → Mitochondria
- Arrow to inner line → Cell membrane
- Arrow to jelly inside → Cytoplasm

Part 2:

- CELL MEMBRANE — This is responsible for controlling what goes in and out of the cell.
- CYTOPLASM — It’s where most of reaction take place. It’s also responsible for giving the cell its shape.
- NUCLEUS — This part holds all of the DNA.
