Which organelle would you expect to find in a plant cell but not a animal cell?

The organelle listed here that you would expect to find in a plant cell but not an animal cell would be the chloroplast. This is what makes leaves green during the spring and summer. It takes in the sunlight and releases chlorophyll. There are actually four types of chlorophyll, which is why you get some plants that are light green and others that are incredibly dark green. This is where photosynthesis takes place in the plant cells.

This raises the question: why do plants change colors in the winter? Well, if the chloroplast is responsible for creating a ton of energy from sunlight for the plant, it would make sense that it can’t do that in the winter with the little sun available.
