What kind of cell organelle would you expect to find in a plant cell but not an animal cell?

Both plant and animal cells contain membrane-bound organelles like mitochrondria and the nucleus. However, only plant cells contain chloroplasts since they need to make sugar from sunlight to perform photosynthesis. Animal cells do not as they can absorb sugar from their food, so they don't need chloroplasts. Their task in life is different.

The answer is Chloroplast. It is a cell organelle which is found only in plant cells.

Chloroplast contains a large amount of chlorophyll ( a substance that makes plants green) in plants and it is highly responsible for the process of photosynthesis. It is a chlorophyll that converts the light energy from the sun into chemical energy.

Without this cell organelle, called chloroplast, plants can't create energy.
