Cell Structures and Functions worksheet with matching exercise and word bank.

Let’s go step by step to match each organelle with its correct function.

We have 8 organelles on the left (1–8) and 11 descriptions on the right (A–K). We need to pick the best letter for each number. Not all letters will be used.

---

1. Nucleus
The nucleus is like the “boss” of the cell — it holds the DNA, which has all the instructions for how the cell works.
→ That matches A. Contains the genetic information of the cell

✔ So, 1 → A

---

2. Vacuole
Vacuoles are storage sacs — they hold water, food, or waste. In plant cells, there’s often one big central vacuole.
→ That matches B. Used for storage of water, food and waste in the cell

✔ So, 2 → B

*(Note: J also mentions storage, but it adds “protein packing and shipping” — that’s more Golgi. So B is better for vacuole.)*

---

3. Golgi Apparatus
This organelle modifies, sorts, and ships proteins and lipids — like a post office.
→ That matches J. Used for storage, protein packing and shipping

✔ So, 3 → J

---

4. Endoplasmic Reticulum (ER)
There are two types: rough ER (with ribosomes) makes proteins; smooth ER makes lipids and transports stuff. Overall, ER helps transport materials inside the cell and connects organelles.
→ That matches I. Transports and stores materials in the cell and connects some organelles together

✔ So, 4 → I

---

5. Ribosome
Ribosomes make proteins — they’re tiny machines that read RNA and build proteins.
→ That matches F. Produces proteins for the cell

✔ So, 5 → F

---

6. Mitochondria
These are the powerhouses of the cell — they make energy (ATP) from food. They work in both animal and plant cells.
→ That matches K. Produce chemical energy for animal and plant cells

*(E says “for the plant cell” only — so K is better because mitochondria work in BOTH.)*

✔ So, 6 → K

---

7. Chloroplast
Only in plant cells — they use sunlight to make food (photosynthesis), producing chemical energy.
→ That matches E. Produces chemical energy for the plant cell

✔ So, 7 → E

---

8. Cell Membrane
This is the outer boundary of the cell (in animals) or just inside the cell wall (in plants). It controls what goes in and out.
→ That matches G. Controls the materials coming in and out of the cell

✔ So, 8 → G

---

Now let’s double-check we didn’t reuse any letters and that all answers make sense:

1. Nucleus → A ✔
2. Vacuole → B ✔
3. Golgi → J ✔
4. ER → I ✔
5. Ribosome → F ✔
6. Mitochondria → K ✔
7. Chloroplast → E ✔
8. Cell Membrane → G ✔

Unused letters: C, D, H — that’s fine, since the instructions say not all will be used.

C = Controls functions → that’s nucleus, already matched to A
D = Support/protection for plant cell → that’s cell wall (not listed in our 8 items)
H = Fluid inside cell → cytoplasm (also not in our list)

So everything checks out!

Final Answer:
1. A
2. B
3. J
4. I
5. F
6. K
7. E
8. G
