Here's why:
* Chloroplasts are responsible for photosynthesis, the process of converting sunlight into energy. Animal cells do not need to perform photosynthesis as they obtain energy from consuming other organisms.
Let's look at the other options:
* Mitochondria are found in both plant and animal cells. They are the "powerhouses" of the cell, responsible for cellular respiration.
* Ribosomes are also found in both plant and animal cells. They are responsible for protein synthesis.
* Vacuoles are found in both plant and animal cells, although they are much larger and more prominent in plant cells. They store water, nutrients, and waste products.
