National 4/5 Biology

1. National 4/5 Biology Unit 1: Cell Biology Section a: Cell Structure and Function

2. What do you remember? A B C D

3. Fungal cells e.g. yeast Which structures do fungal cells like yeast have in common with a plant cell? Is yeast a plant cell? Explain your answer Which structures do fungal cells like yeast have in common with an animal cell? Is yeast an animal cell? Explain your answer

4. Bacterial Cells Chromosome Plasmid • Which structures do bacterial cells have in common with plant cells? • Can bacterial cells be classed as plant cells? Explain your answer • Which structures do bacterial cells have in common with animal cells? • Can bacterial cells be classed as animal cells? Explain your answer • What feature do bacterial cells have that plant, animal or fungal cells do not have? A plasmid is a circular piece of genetic material. It can be used to transfer a gene from one organism to another

5. Practical • Your teacher will show you how to prepare slides of plant, animal and fungal cells • In your groups you should be thinking about what the different types of cells have in common and how they are different

6. Summary
