Difference between animal and plant cells Look at your bacterium • How many differences can you see between animal/plant cells and a bacterial cell? • List the similarities and differences • Bacteria are prokaryotes * ** *** Name some parts of a bacterial cell Compare the structure of bacteria with animal and plant cells Explain how yeast (and bacteria) are useful to us
Yeast cells • What do they look like? • What do we know about yeast? * ** *** Name some parts of a bacterial cell Compare the structure of bacteria with animal and plant cells Explain how yeast (and bacteria) are useful to us
Yeast cells • Yeast cells are traditionally used in baking and brewing. This is because yeast can respire anaerobically in a process called fermentation • Yeast will respire aerobically if they have enough oxygen • Yeast cells reproduce asexually by a process called budding * ** *** Name some parts of a bacterial cell Compare the structure of bacteria with animal and plant cells Explain how yeast (and bacteria) are useful to us
