Chloroplasts and mitochondria are organelles that act as cellular power stations. Chloroplasts harness light energy from the sun through photosynthesis to produce sugars and oxygen in plant and algal cells. Mitochondria convert the sugars produced by chloroplasts into ATP through cellular respiration, providing energy for all eukaryotic cells. Both organelles have double membranes and internal structures that allow them to perform these essential energy conversion functions.

1. Chloroplasts & Mitochondria * Compare and contrast the functions of chloroplasts and mitochondrion The cellular machinery requires a coninuous energy supply to do all the work of life. The two types of cellular power stations are organelles called chloroplasts & mitochondria . One harnesses light energy from the sun, and the other "unpacks" this captured energy into smaller packets that are useful for powering cellular work.

2. The cellular machinery requires a continuous energy supply to do all the work of life.

3. The two types of cellular power stations are organelles called chloroplasts & mitochondria .

4. One harnesses light energy from the sun, and the other "unpacks" this captured energy into smaller packets that are useful for powering cellular work.

5. Cellular Respiration The process by which cells make ATP

6. Photosynthesis Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and C 6 H 12 O 6 (glucose or sugar) .

7. Chloroplasts Plants and algae (plant-like protists) harness light energy through photosynthesis. Found only in Eukarya autotrophs/producers the sun sugar

8. Chloroplasts Light Energy + water & carbon dioxide Sugars (which are used as chemical energy) & oxygen Found only in Eukarya autotrophs or producers

9. Two membranes Fluid filled space ( stroma ) Disk shaped structures ( thylakoids ) Stack of disks ( granum ) Multiple stacks ( grana )
