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 transport sperm.

> Note: The diagram shows the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis. But since only A–E are labeled, we focus on those.

#### Female Reproductive System (Right Diagram):
- F: Ovary – produces eggs (ova) and sex hormones like estrogen and progesterone.
- G: Fallopian tube (Oviduct) – where fertilization usually occurs; transports egg from ovary to uterus.
- H: Uterus – where a fertilized egg implants and develops into a fetus.
- I: Cervix – the neck of the uterus; connects uterus to vagina.
- J: Vagina – the canal leading from the cervix to the outside; receives sperm during intercourse.

✔ Answers for Question 1:

| 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 of reproductive organs

Now match each organ with its correct function using lines. One is already done:

- Ovary → Where ova are produced ✔

Let’s go through the rest:

#### Organs:
- 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 (also called vas deferens) → Tube carrying sperm out of the penis

✔ 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

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. These include the development of secondary sexual characteristics, growth spurts, and the maturation of reproductive organs.

> ✔ Example answer:
> *The body begins to develop secondary sexual characteristics, such as breast development in girls and facial hair in boys, due to increased hormone production.*

---

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

Answer:
1. Breast development (breasts grow and become more prominent).
2. Menstruation begins (monthly menstrual cycle starts).

> Other acceptable answers:
> - Growth of pubic and underarm hair
> - Widening of hips
> - Increase in height (growth spurt)

---

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

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

> Other acceptable answers:
> - Increased self-awareness
> - Development of interest in relationships or romance
> - Feelings of anxiety or confusion about changing bodies
