Specialized Cells worksheet - Free Printable

Let’s go step by step to solve this worksheet on specialized cells.

---

First, let’s identify the cells in the diagram based on their shapes and features:

- Cell A: Has a large nucleus and irregular shape — looks like a white blood cell (leukocyte). It fights infection.
- Cell B: Long, striated fiber — that’s a muscle cell (specifically skeletal muscle).
- Cell C: Round, no nucleus, biconcave disc shape — these are red blood cells (erythrocytes). They carry oxygen.
- Cell D: Large round cell with a big nucleus and lots of cytoplasm — likely an egg cell (ovum).
- Cell E: Small cell with a tail — sperm cell.
- Cell F: Has dendrites and axon — nerve cell (neuron).

Now answer each part:

---

a) Identify the cells A, B, and C

A → White blood cell
B → Muscle cell
C → Red blood cell

*(Note: Sometimes “muscle cell” is called “muscle fiber” or “skeletal muscle cell” — but for school level, “muscle cell” is fine.)*

---

b) Which two cells are the reproductive cells (gametes)?

Gametes = sex cells → sperm and egg.

From diagram:
- E = sperm
- D = egg

So:
I. E (sperm)
II. D (egg)

c) Name the cell which contains the pigment hemoglobin.

Hemoglobin is in red blood cells → Cell C.

Answer: Red blood cell (or erythrocyte)

d) Fill in the blank spaces to complete the table.

We need to match cell names with functions.

Table rows:

1. Function: “Fuses with the egg to form a zygote” → That’s the sperm cell → so Cell = E

2. Cell: A → We said A is white blood cell → Function: Destroys pathogens / fights infection

3. Function: “Carries electrical impulses” → That’s the nerve cell → Cell = F

4. Cell: C → Red blood cell → Function: Transports oxygen (using hemoglobin)

Let’s fill it properly:

| Cell | Function |
|------|-----------------------------------|
| E | Fuses with the egg to form a zygote |
| A | Destroys germs / fights infection |
| F | Carries electrical impulses |
| C | Transports oxygen |

*(Note: For Cell A, you can also say “engulfs bacteria” or “part of immune system” — but “fights infection” is simple and correct.)*

✔ All answers checked and verified.

Final Answer:

a)
A. White blood cell
B. Muscle cell
C. Red blood cell

b)
I. E (sperm)
II. D (egg)

c) Red blood cell

d)
| Cell | Function |
|------|-----------------------------------|
| E | Fuses with the egg to form a zygote |
| A | Fights infection |
| F | Carries electrical impulses |
| C | Transports oxygen |
