Bioenergetics+Scenarios

Bioenergetics scenarios –

1. What is the role of the mitochondria for cells? 2. What is the role of a chloroplast for cells. 3. Draw a mitochondrion and a chloroplast. List 2 similarities and 2 differences. 4. Use google images, draw a skin cell (flat pancake), muscle cell (long spindle) and an intestinal cell (tall column with hairs on top). Add a nucleus to all cells! Write the numbers 400, 15,000 and 8,000 into each cell, respectively. Answer this: Why would there be more mitochondria in one cell than the other? Discuss all three cell types in your answer. 5. Draw a plant. Write 0 by the roots, 25 by the stem and 200 by the leaves. Each number represents the number of chloroplasts per cell in those organs of the plant. Answer this: Why would there be more chloroplasts in one cell than the other? Discuss all three cell types in your answer. 6. Google an image of a plant cell. Do plant cells contain mitochondria? Why or why not? 7. Google an image of an animal cell. Do animal cells contain chloroplasts? Why or why not? 8. Google an image of a bacterium. Do bacteria have mitochondria or chloroplasts? If not, how do they get their energy?
