Specialised Cells Write down as many different types of cell as you can! 3 minutes! What are these? 2 1 3 6 4 Plant leaf cell Ciliated epithelial cell Animal cell 5 Sperm cell Plant root hair cell Egg cell 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 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: 1. What the term ‘haploid nucleus’ means and why it is important that sperm and egg cells are haploid 2. What happens to the egg cell membrane after a sperm enters
