Reproductive System worksheet - Free Printable

Let's solve each part of this biology task step by step, based on the diagrams and questions provided.

1. Identify the organs in the male and female reproductive systems

We are given two diagrams: one of the male reproductive system (left) and one of the female reproductive system (right). Let’s identify each labeled part.

#### Male Reproductive System (Left Diagram):
- A: Epididymis – a coiled tube where sperm mature and are stored.
- B: Vas deferens – carries sperm from the epididymis to the ejaculatory duct.
- C: Seminal vesicle – produces fluid that mixes with sperm to form semen.
- D: Testis – produces sperm and testosterone.
- E: Prostate gland – adds fluid to semen; helps nourish and protect sperm.

> Note: The diagram may not show all glands clearly, but based on standard labeling:
> - A is often the epididymis
> - B is the vas deferens
> - C could be the seminal vesicle or bulbourethral gland — but here it's likely seminal vesicle
> - D is testis
> - E is prostate gland

#### Female Reproductive System (Right Diagram):
- F: Ovary – produces eggs (ova) and hormones like estrogen and progesterone.
- G: Fallopian tube (oviduct) – where fertilization occurs.
- H: Uterus – where a fertilized egg implants and develops into a fetus.
- I: Cervix – the neck of the uterus, connects to the vagina.
- J: Vagina – passage for menstrual flow and birth canal.

✔ So, fill in the blanks:

| Letter | Organ Name |
|--------|--------------------------|
| A | Epididymis |
| B | Vas deferens |
| C | Seminal vesicle |
| D | Testis |
| E | Prostate gland |
| F | Ovary |
| G | Fallopian tube (Oviduct) |
| H | Uterus |
| I | Cervix |
| J | Vagina |

2. Match the functions to the organs

We are given a list of organs and their functions. One has already been matched:
Ovary → Where ova are produced

Now match the rest:

- Uterus → Where a fertilised egg can develop
- Oviduct → Where the ovum can be fertilised
- Cervix → The base of the uterus
- Testis → Where the sperm are produced
- Gland (likely refers to seminal vesicles or prostate) → Produces a fluid for the sperm to swim in
- Penis → Places sperm in the vagina during intercourse
- Sperm duct (vas deferens) → Tube carrying sperm out of the penis

Now draw lines accordingly:

```
Ovary → Where ova are produced
Uterus → Where a fertilised egg can develop
Oviduct → Where the ovum can be fertilised
Cervix → The base of the uterus
Testis → Where the sperm are produced
Gland → Produces a fluid for the sperm to swim in
Penis → Places sperm in the vagina during intercourse
Sperm duct → Tube carrying sperm out of the penis
```

✔ All matched correctly.

3a. Puberty Questions

#### i) What happens to a child's body during puberty?
(1 mark)

Answer:
During puberty, a child's body undergoes physical changes as it develops into an adult capable of reproduction. This includes the development of secondary sexual characteristics, growth spurt, and maturation of reproductive organs.

> ✔ Example answer:
> *The body changes to become sexually mature, including growth of reproductive organs and development of secondary sexual characteristics.*

---

#### ii) Give two changes which take place in a girl's body at puberty.
(2 marks)

Answer:
1. Development of breasts
2. Growth of pubic and underarm hair
3. Start of menstruation (menarche)
4. Widening of hips

> ✔ Any two of these are acceptable.

> Example:
> - Breast development
> - Onset of menstruation

---

#### iii) Give one emotional change which takes place in both boys and girls at puberty.
(1 mark)

Answer:
Increased mood swings or emotional sensitivity due to hormonal changes.

> ✔ Example:
> *They may feel more anxious, irritable, or experience strong emotions.*
