Let's solve the problem step by step based on the diagram and questions provided.

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

We are given a diagram showing both male and female reproductive systems with blank boxes to label. Let’s identify each part:

#### Male Reproductive System (Left Diagram):
- The large oval structures at the bottom are the testes – they produce sperm.
- The tube-like structure extending upward from the testes is the vas deferens – it transports sperm.
- The structure above the vas deferens, shaped like a funnel, is the seminal vesicle or ejaculatory duct (but more accurately, the prostate gland is near the base).
- However, in standard labeling:
- The two round structures at the bottom → Testes
- The tube leading from the testes → Vas deferens
- The structure at the top of the left side → Epididymis (where sperm mature)
- But since only three labels are shown, we need to match the positions.

Looking at the positions of the blanks:

1. Top-left blank (pointing to the epididymis or ductus deferens) → likely Epididymis (sperm matures here).
2. Bottom-left blank (pointing to the testes) → Testes.
3. Right-side blank (on the female side) → pointing to the ovary.
4. Bottom-right blank (on the female side) → pointing to the vagina.

So:

- Male side:
- Top-left → Epididymis
- Bottom-left → Testes
- Female side:
- Top-right → Ovary
- Bottom-right → Vagina

✔ So, fill in the blanks as:
- Left-top: Epididymis
- Left-bottom: Testes
- Right-top: Ovary
- Right-bottom: Vagina

> Note: Some diagrams may vary slightly, but these are the most accurate based on common anatomy.

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

We are given a table:

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

Answer:

- To produce eggs → Ovaries
- To produce sperm → Testes

✔ Fill in the table:

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

Question 1c: Stages in human development

The diagram shows:

1. Zygote → fertilized egg
2. Then → Embryo (after first few cell divisions, up to about 8 weeks)
3. Then → Fetus (from week 9 until birth)
4. Finally → Baby

So, fill in the blanks:

- Zygote → Embryo → Fetus → Baby

✔ Answer:
- First blank: Embryo
- Second blank: Fetus

---

✔ Final Answers:

#### a) Labels:
- Male:
- Top-left: Epididymis
- Bottom-left: Testes
- Female:
- Top-right: Ovary
- Bottom-right: Vagina

#### b) Table:
| Parts of human reproductive system | Function |
|----------------------------------|----------|
| Ovaries | To produce eggs |
| Testes | To produce sperm |

#### c) Stages of development:
- Zygote → Embryo → Fetus → Baby

This completes the solution to all parts of the question.
