Step-by-step solution for: Sperm Cell: Specialised Cells | PDF | Egg | Lung
Let's solve the worksheet on Specialised Cells by filling in the blanks based on biological knowledge. Here’s a complete and accurate solution with explanations for each cell type.
---
- Designed to *fertilise an egg cell*
→ Sperm cells are male gametes whose main function is to fuse with an egg (ovum) during reproduction.
- Found in the testes
→ Sperm cells are produced in the testes, the male reproductive organs.
- A sperm is small and has a long tail that provides movement so it can swim and find an egg cell.
→ The tail (flagellum) enables motility, allowing the sperm to travel through the female reproductive tract.
- The acrosome contains enzymes which allow it to digest into an egg cell and join with it.
→ The acrosome is a cap-like structure at the head of the sperm containing enzymes (like hyaluronidase and proteases) that help penetrate the outer layers of the egg.

- Designed to be fertilised
→ The egg cell is the female gamete, designed to be fertilised by a sperm.
- Found in the ovaries
→ Egg cells are produced in the ovaries.
- Contains yolk which provides a large amount of food for the new cell being formed.
→ The yolk (or vitellus) is rich in nutrients and energy reserves to support early embryonic development.
✔ Completed:
> - Designed to be fertilised
> - Found in the ovaries
> - Contains yolk which provides a large amount of food for the new cell being formed.

- Designed for photosynthesis
→ Palisade cells are found in the leaves of plants and are specialised for photosynthesis.
- Tall and has a large surface area to absorb light and carbon dioxide
→ Their shape maximises exposure to sunlight and allows efficient gas exchange (CO₂ enters for photosynthesis).
- Packed with chloroplasts to help make glucose and oxygen
→ Chloroplasts contain chlorophyll, which captures light energy to produce glucose and oxygen via photosynthesis.
✔ Completed:
> - Designed for photosynthesis
> - Tall and has a large surface area to absorb light and carbon dioxide
> - Packed with chloroplasts to help make glucose and oxygen

- Designed to stop pathogens entering the lungs
→ These cells line the respiratory tract and protect against infection.
- They line all the air passages in the lungs.
→ Ciliated cells are found in the trachea, bronchi, and bronchioles.
- They have tiny hairs called cilia.
→ Cilia are microscopic hair-like structures that move rhythmically.
- Hairs sweep mucus with trapped dust and bacteria back up the throat.
→ The cilia beat in coordinated waves to move mucus (which traps harmful particles) toward the throat, where it can be swallowed or expelled.
✔ Completed:
> - Designed to stop pathogens entering the lungs
> - They line all the air passages in the lungs.
> - They have tiny hairs called cilia.
> - Hairs sweep mucus with trapped dust and bacteria back up the throat.
