Plant cells can use energy from the sun to make food. Animal cells cannot. Which organelle is responsible for this difference between plant and animal cells?

Answer 1

The organelle responsible for the difference between plant and animal cells in their ability to use energy from the sun to make food is the chloroplast. Chloroplasts are only present in plant cells and are the site of photosynthesis, the process by which plants convert sunlight into energy-rich molecules such as glucose. Animal cells lack chloroplasts, and therefore cannot perform photosynthesis. Instead, animal cells obtain energy from other sources, such as consuming other organisms or ingesting organic molecules.
