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 – the duct that carries sperm from the epididymis to the ejaculatory duct.
- C: Seminal vesicle – gland that produces fluid for semen.
- D: Testis – produces sperm and testosterone.
- E: Prostate gland – surrounds the urethra and adds fluid to semen.

> Note: In some diagrams, C might be the ejaculatory duct, but here it's more likely the seminal vesicle since it's near the vas deferens and above the prostate. But let’s double-check:
>
> - The ejaculatory duct forms when the vas deferens joins the seminal vesicle.
> - Here, C is shown as a small sac-like structure beside the vas deferens → likely seminal vesicle.
> - E is the prostate gland, which surrounds the urethra below the bladder.

So:

| Letter | Organ Name |
|--------|------------|
| A | Epididymis |
| B | Vas deferens |
| C | Seminal vesicle |
| D | Testis |
| E | 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 the embryo develops.
- I: Cervix – the neck of the uterus; connects to the vagina.
- J: Vagina – canal leading to the outside; receives sperm and birth canal.

| Letter | Organ Name |
|--------|------------|
| F | Ovary |
| G | Fallopian tube (Oviduct) |
| H | Uterus |
| I | Cervix |
| J | Vagina |

✔ Answers for Question 1:

```
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 of the reproductive organs

We need to match each organ with its correct function.

Given list:

Organs:
- Ovary
- Uterus
- Oviduct
- Cervix
- Testis
- Gland
- Penis
- Sperm duct

Functions:
- Places sperm in the vagina during intercourse
- Produces a fluid for the sperm to swim in
- Where the sperm are produced
- Where ova are produced
- Where a fertilised egg can develop
- Tube carrying sperm out of the penis
- The base of the uterus
- Where the ovum can be fertilised

Now, match them:

- 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 *(e.g., seminal vesicles, prostate)*
- Penis → Places sperm in the vagina during intercourse
- Sperm duct → Tube carrying sperm out of the penis *(Note: This is the same as vas deferens or ejaculatory duct)*

✔ Matching:

- 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

> You already have one done: Ovary → Where ova are produced.

3a. Puberty Questions

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

Answer:
During puberty, a child's body undergoes physical and hormonal changes that lead to sexual maturity. This includes the development of secondary sexual characteristics, growth spurts, and the maturation of reproductive organs.

> Example answer (1 mark):
> *The body begins to develop secondary sexual characteristics and reproductive organs mature.*

---

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

Answer (2 marks):
1. Breast development – breasts begin to grow and become larger.
2. Menstruation starts – monthly periods begin as the reproductive system matures.
> Other acceptable answers: Growth of pubic and underarm hair, widening of hips, voice deepening slightly.

---

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

Answer (1 mark):
- Increased mood swings due to hormonal changes.
- Development of interest in the opposite sex.
- Greater self-awareness and sensitivity.

> Example answer:
> *Increased emotional sensitivity or mood swings.*

2. Function Matching

- 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

*(Draw lines accordingly on the diagram.)*

3a. Puberty

i) During puberty, a child's body undergoes physical and hormonal changes leading to sexual maturity, including growth spurts and development of secondary sexual characteristics.

ii) Two changes in a girl’s body:
- Breast development
- Start of menstruation (menstrual cycle)

iii) One emotional change common to both boys and girls:
- Mood swings due to hormonal changes
