Question

what process occurs in mitochondria?
what process occurs in chloroplasts?
do plants have only chloroplasts, only mitochondria, or both?
plants are autotrophic. what does that mean?
animals are heterotrophic. what does that mean?

Explanation:

1. Mitochondria are the site of energy release from glucose.
2. Chloroplasts are the site of glucose production from light.
3. Plant cells need both organelles for energy and food.
4. Autotrophs make their own organic food.
5. Heterotrophs rely on other organisms for food.

Answer:

1. Cellular respiration occurs in mitochondria.
2. Photosynthesis occurs in chloroplasts.
3. Plants have both chloroplasts and mitochondria.
4. It means plants can produce their own food (glucose) via photosynthesis using light, water, and carbon dioxide.
5. It means animals cannot make their own food, so they must consume other organisms (plants or other animals) to obtain energy and nutrients.
