1. Specialised Cells Write down as many different types of cell as you can! 3 minutes!

2. What are these? 2 1 3 Ciliated epithelial cell 6 Animal cell
Plant leaf cell 4 5
Sperm cell
Plant root hair cell
Egg cell

3. Objectives
To be able to describe the features/structures of specialised cells, and explain how they are related to their function
Egg cell
Sperm cell
Ciliated epithelial cell

4. Task: learning about specialised cells:
Use the worksheet to draw a diagram of each type of cell, labelling the key features. Add detail to explain the function of each feature:
a) sperm cells – acrosome, haploid nucleus, mitochondria and tail
b) egg cells – nutrients in the cytoplasm, haploid nucleus
c) ciliated epithelial cells – cilia
Extension: Explain the following:
What the term ‘haploid nucleus’ means and why it is important that sperm and egg cells are haploid
What happens to the egg cell membrane after a sperm enters
