Cell Organelles and Their Functions worksheet with a list of organelles and their roles in plant and animal cells.

Let’s go through each clue one by one and match it to the correct organelle from the list.

---

Clue 1: *This is the outermost cover of the cell.*
→ That’s the Cell Membrane (it surrounds the cell, even if there’s a cell wall outside in plants).
✔ Match: 12

---

Clue 2: *This is made of DNA and is the storage area for all genetic information.*
→ That’s the Nucleus — it holds the cell’s DNA.
✔ Match: 13

---

Clue 3: *This is the site of protein synthesis in a cell.*
→ Protein synthesis happens at the Ribosome.
✔ Match: 11

---

Clue 4: *This protein structure surrounds the nucleus, helping it function.*
→ That’s the Nuclear Membrane (also called nuclear envelope).
✔ Match: 8

---

Clue 5: *This internal membrane system is so extensive that it accounts for more than half the total membrane in the cell.*
→ That’s the Endoplasmic Reticulum — especially the rough ER with ribosomes.
✔ Match: 6

---

Clue 6: *When newly formed proteins leave the rough endoplasmic reticulum, they are transported to another organelle where the proteins are packaged and sorted for shipping.*
→ That’s the Golgi Apparatus — it modifies, sorts, and packages proteins.
✔ Match: 10

---

Clue 7: *This is the site of the cell manufacture the ribosomal subunits.*
→ Ribosomal subunits are made in the Nucleolus (inside the nucleus).
✔ Match: 14

---

Clue 8: *The site of the cell which chromosomes would be found to protect the rest of the cell from the strong acids.*
→ Chromosomes are in the Nucleus, which protects DNA.
✔ Match: 13

---

Clue 9: *The part of the cell that controls what enters and leaves the cell.*
→ That’s the Cell Membrane again — it’s selectively permeable.
✔ Match: 12

---

Clue 10: *The part of the cell where chromosomes would be found.*
→ Again, Nucleus.
✔ Match: 13

---

Clue 11: *The part of the cell where chromosomes would be found to protect the rest of the cell from the strong acids.*
→ Still Nucleus — same as clue 8 and 10.
✔ Match: 13

Wait — this seems repetitive. Let’s check if we’re missing something. Actually, looking back, clues 8, 10, and 11 all point to the nucleus. But maybe clue 11 is trying to say something else? No — it says “chromosomes would be found” — definitely nucleus.

But let’s keep going.

---

Clue 12: *The organelle connects to the nuclear membrane.*
→ The Endoplasmic Reticulum connects to the nuclear membrane.
✔ Match: 6

---

Clue 13: *This part of the cell contains strong digestive enzymes to break down proteins, carbohydrates and other molecules that can be used by the cell as food.*
→ That’s the Lysosome — it digests waste and old parts.
✔ Match: 7

---

Clue 14: *These are the membranes of the cell’s organelles.*
→ This is tricky. All organelles have membranes, but the best fit here is Cell Membrane? Wait — no, it says “membranes of the cell’s organelles” — plural. Maybe it’s referring to the general concept? But looking at the list, perhaps it’s Cell Membrane again? Hmm.

Actually, re-reading: “These are the membranes of the cell’s organelles.” — this might be poorly worded. Perhaps it means the membrane surrounding the cell? But that’s already covered.

Wait — maybe it’s Cell Membrane because it’s the main membrane? Or perhaps it’s a trick.

Looking at the answer choices, maybe it’s Cell Membrane — but that doesn’t make sense because it says “organelles’ membranes”.

Alternatively, maybe it’s Nuclear Membrane? But that’s only one organelle.

Wait — perhaps it’s Endoplasmic Reticulum? Because it’s an internal membrane system.

But clue 5 already used ER.

Let’s skip and come back.

---

Clue 15: *This is the cell’s “powerhouse” where ATP is made.*
→ Classic definition: Mitochondrion.
✔ Match: 5

---

Clue 16: *The place where lipids are manufactured.*
→ Lipids are made in the Smooth Endoplasmic Reticulum — which is part of the ER. Since ER is listed as #6, and smooth ER is a type of ER, we’ll use 6.
✔ Match: 6

---

Clue 17: *This part contains the instructions for making proteins and other important molecules.*
→ Instructions = DNA → Nucleus.
✔ Match: 13

---

Clue 18: *This organelle consists of two types of membranes that include microfilaments and microtubules.*
→ This sounds like the Cytoskeleton — which is made of microfilaments and microtubules.
✔ Match: 3

---

Clue 19: *Choose 2 of the organelles from the list above that would never be found in a plant cell.*
→ Plant cells have: cell wall, chloroplasts, large vacuole, etc.
Animal cells have: centrioles, lysosomes (sometimes), and no cell wall or chloroplasts.

From the list:
- Centriole (#2) — not in plant cells (usually)
- Lysosome (#7) — sometimes debated, but often considered animal-only in basic biology
- Also, maybe “Cell Membrane” is in both, so not that.

Standard answer: Centriole and Lysosome — though lysosomes are sometimes in plants, in many curricula they’re taught as animal-only.

But let’s see the options:
Available: 2 (Centriole), 7 (Lysosome)

So: 2 and 7

✔ Match: 2, 7

---

Clue 20: *These serve as storage sacs for food, water, and waste.*
→ That’s the Vacuole — especially large in plant cells.
✔ Match: 15

---

Clue 21: *This is the same fluid portion found inside the nucleus.*
→ Fluid inside nucleus is Nucleoplasm.
✔ Match: 14

Wait — clue 7 was also nucleolus? No, clue 7 was “site of ribosomal subunit manufacture” → nucleolus (#14). Clue 21 is “fluid portion inside nucleus” → nucleoplasm (#14)? But nucleoplasm is #14? Wait, let’s check the list:

Looking back at the original list:

13 Nucleus
14 Nucleolus
15 Vacuole
...

Wait — where is nucleoplasm? It’s not explicitly listed! Oh no — problem.

In the original list provided in the image:

Looking at the user’s image description:

The list includes:

12 Cell Membrane
13 Nucleus
14 Nucleolus
15 Vacuole

But nucleoplasm is not listed! So clue 21 must be referring to something else.

Wait — perhaps it’s a trick. The fluid inside the nucleus is nucleoplasm, but if it’s not in the list, maybe they mean the nucleus itself? But that’s not fluid.

Alternatively, perhaps it’s a mistake, and they mean cytoplasm? But cytoplasm is not listed either.

Wait — looking back at the original list in the user’s message:

The list has:

1 Cell Membrane
2 Centriole
3 Cytoskeleton
4 Chloroplast
5 Mitochondrion
6 Endoplasmic Reticulum
7 Lysosome
8 Nuclear Membrane
9 Rough endoplasmic reticulum
10 Golgi apparatus
11 Ribosome
12 Cell Membrane (duplicate?)
13 Nucleus
14 Nucleolus
15 Vacuole

Wait — in the user’s text, it says:

“12 Cell Membrane” — but earlier “1 Cell Membrane” — so duplicate.

And “9 Rough endoplasmic reticulum” — which is part of ER.

But nucleoplasm is not listed.

Perhaps clue 21 is meant to be “cytoplasm”, but cytoplasm isn't listed.

Wait — maybe it’s “nucleoplasm” and they expect us to choose from available, but it’s not there.

Alternatively, perhaps it’s a typo, and they mean the fluid in the cell — cytoplasm — but again, not listed.

Let’s read clue 21 again: *“This is the same fluid portion found inside the nucleus.”*

If nucleoplasm is not in the list, perhaps they want “Nucleus” — but that’s not fluid.

Maybe “Nuclear Membrane” — no.

Another thought: sometimes “nucleoplasm” is considered part of the nucleus, so perhaps they want “Nucleus” — but that’s not accurate.

Wait — looking at the list, item 14 is “Nucleolus” — which is a structure inside the nucleus, not the fluid.

Perhaps the answer is not available, but that can’t be.

Wait — in some contexts, “nucleoplasm” is listed separately, but here it’s not.

Perhaps clue 21 is meant to be matched with “Nucleus” — even though it’s not precise.

But let’s think differently. Maybe “the same fluid portion” refers to cytoplasm, but cytoplasm is not listed.

Wait — item 3 is “Cytoskeleton” — not fluid.

I think there might be an error in the worksheet, but since we have to choose from the list, and nucleoplasm isn’t there, perhaps they mean the nucleus — but that’s not fluid.

Another idea: perhaps “nuclear membrane” contains fluid? No.

Let’s look at clue 4: “This protein structure surrounds the nucleus” — that’s nuclear membrane.

Clue 21: “fluid portion found inside the nucleus” — should be nucleoplasm.

Since it’s not listed, and the closest is “Nucleus” or “Nucleolus”, but neither is fluid.

Perhaps it’s a trick, and they want “Nucleus” — I’ll go with that for now, but it’s not accurate.

Wait — in the list, is there “Cytoplasm”? No.

Let’s count the clues: there are 21 clues, and 15 items, but some items are used multiple times.

For clue 21, since nucleoplasm isn’t listed, and the nucleus contains the nucleoplasm, perhaps they expect “Nucleus” — but that’s misleading.

Alternatively, maybe “Nuclear Membrane” — no.

I recall that in some worksheets, they might consider “nucleoplasm” as part of the nucleus, so perhaps answer is 13.

But let’s see if there’s another possibility.

Wait — item 14 is “Nucleolus” — which is inside the nucleus, but it’s a body, not fluid.

Perhaps the answer is not among the list, but that can’t be.

Another thought: maybe “the same fluid portion” refers to cytoplasm, and cytoplasm is not listed, but “Cytoskeleton” is close? No.

I think there might be a mistake in the worksheet, but for the sake of completing, I’ll assume that “Nucleus” is the intended answer for clue 21, even though it’s not precise.

But let’s double-check the original list in the user’s message:

The user wrote:

“13 Nucleus
14 Nucleolus
15 Vacuole”

No nucleoplasm.

Perhaps in some curricula, they use “nucleus” to include the fluid.

I’ll go with 13 for clue 21.

But let’s confirm with standard knowledge: nucleoplasm is the fluid, nucleus is the organelle.

Perhaps the answer is “Nuclear Membrane” — but that’s not fluid.

I think it’s a flaw, but we’ll proceed.

---

Now, let’s compile all answers:

1. Cell Membrane → 12
2. Nucleus → 13
3. Ribosome → 11
4. Nuclear Membrane → 8
5. Endoplasmic Reticulum → 6
6. Golgi Apparatus → 10
7. Nucleolus → 14
8. Nucleus → 13
9. Cell Membrane → 12
10. Nucleus → 13
11. Nucleus → 13
12. Endoplasmic Reticulum → 6
13. Lysosome → 7
14. ??? — let’s revisit

Clue 14: *“These are the membranes of the cell’s organelles.”*

This is ambiguous. Perhaps it’s referring to the cell membrane, but that’s only one.

Maybe it’s “Endoplasmic Reticulum” because it’s a membrane system.

Or perhaps “Nuclear Membrane” — but again, only one.

Another idea: in some contexts, “membranes of organelles” could refer to the endomembrane system, which includes ER, Golgi, etc., but the question asks for a single organelle.

Perhaps it’s “Cell Membrane” — but that’s not for organelles.

I think the best fit is Endoplasmic Reticulum because it’s an extensive membrane system.

So for clue 14: 6

But clue 5 and 12 also use 6.

That’s fine, since organelles can be used multiple times.

Clue 15: Mitochondrion → 5
Clue 16: Smooth ER → part of ER → 6
Clue 17: Nucleus → 13
Clue 18: Cytoskeleton → 3
Clue 19: Centriole and Lysosome → 2 and 7
Clue 20: Vacuole → 15
Clue 21: Nucleus → 13 (assuming)

But let’s list all with numbers:

1. 12
2. 13
3. 11
4. 8
5. 6
6. 10
7. 14
8. 13
9. 12
10. 13
11. 13
12. 6
13. 7
14. 6 (assuming ER for membranes of organelles)
15. 5
16. 6
17. 13
18. 3
19. 2,7
20. 15
21. 13

Now, for clue 19, it says “choose 2”, so we list both.

In the final answer, we need to provide the numbers for each clue.

But the instruction is to provide the final answer as the matched numbers.

Since it’s a matching exercise, the final answer should be the sequence of numbers corresponding to each clue.

So for clues 1 to 21, the answers are:

1: 12
2: 13
3: 11
4: 8
5: 6
6: 10
7: 14
8: 13
9: 12
10: 13
11: 13
12: 6
13: 7
14: 6
15: 5
16: 6
17: 13
18: 3
19: 2,7
20: 15
21: 13

For clue 19, since it’s two, we write "2,7"

Now, to present the final answer, we can list them in order.

But the problem says "provide only the final correct answer", so perhaps a list.

Since it's a worksheet, likely they want the numbers filled in.

So the final answer is the sequence:

12, 13, 11, 8, 6, 10, 14, 13, 12, 13, 13, 6, 7, 6, 5, 6, 13, 3, 2,7, 15, 13

But for clue 19, it's two numbers, so in the sequence, it might be listed as "2,7" for that position.

In the response, we can write it as a list.

Perhaps box the entire sequence.

But let's make sure about clue 14 and 21.

For clue 14: "These are the membranes of the cell’s organelles." — I think "Endoplasmic Reticulum" is reasonable, as it's a major membrane system.

For clue 21: "This is the same fluid portion found inside the nucleus." — since nucleoplasm isn't listed, and nucleus is the organelle that contains it, I'll stick with 13.

Some might argue for "Nuclear Membrane", but that's not fluid.

So I think it's acceptable.

Final Answer:

12, 13, 11, 8, 6, 10, 14, 13, 12, 13, 13, 6, 7, 6, 5, 6, 13, 3, 2,7, 15, 13

But to write it neatly.

Since the user might expect the answers in order, and for clue 19, it's two, so in the sequence, position 19 is "2,7".

In the final answer, we can list them as:

Clue 1: 12
Clue 2: 13
...
Clue 19: 2,7
etc.

But the instruction says "provide only the final correct answer", so perhaps a comma-separated list.

I think it's fine.

So the final answer is:

12, 13, 11, 8, 6, 10, 14, 13, 12, 13, 13, 6, 7, 6, 5, 6, 13, 3, 2,7, 15, 13

But to make it clear, perhaps write it as a sequence.

Since it's for a student, we can list the numbers in order.

I think that's it.
