Question 1a: Label the parts of the male and female reproductive system

We are given a diagram showing both the male and female reproductive systems. There are four blanks to label:

#### Male Reproductive System (left side):
- The top left structure is the vas deferens (also called the ductus deferens) – it carries sperm from the epididymis to the urethra.
- The bottom left oval structure is the testis (plural: testes) – it produces sperm and testosterone.

> So:
> - Top left blank → Vas deferens
> - Bottom left blank → Testis

#### Female Reproductive System (right side):
- The top right structure is the ovary – it produces eggs (ova).
- The bottom right structure is the vagina – it’s the birth canal and receives sperm during intercourse.

> So:
> - Top right blank → Ovary
> - Bottom right blank → Vagina

✔ Answer for 1a:
- Left top: Vas deferens
- Left bottom: Testis
- Right top: Ovary
- Right bottom: Vagina

Question 1b: Name the parts that produce sperm and egg

We need to fill in the table:

| Parts of human reproductive system | Function |
|------------------------------------|----------|
| | To produce eggs |
| | To produce sperm |

- The ovary produces eggs (ova) in females.
- The testis produces sperm in males.

✔ Answer for 1b:
- To produce eggs → Ovary
- To produce sperm → Testis

Question 1c: Stages in human development

We are shown a sequence:
Zygote → [ ] → [ ] → Baby

The stages of human development after fertilization are:

1. Zygote – formed when sperm and egg fuse.
2. Embryo – the developing organism from the second week to the eighth week after fertilization.
3. Fetus – from the ninth week until birth.
4. Baby – born infant.

So the correct sequence is:
Zygote → Embryo → Fetus → Baby

✔ Answer for 1c:
- First blank → Embryo
- Second blank → Fetus

✔ Final Answers:

#### 1a) Labels:
- Male:
- Top: Vas deferens
- Bottom: Testis
- Female:
- Top: Ovary
- Bottom: Vagina

#### 1b) Table:
| Parts of human reproductive system | Function |
|------------------------------------|----------|
| Ovary | To produce eggs |
| Testis | To produce sperm |

#### 1c) Development stages:
- Zygote → Embryo → Fetus → Baby
