Why do plant cells have chloroplasts, but animal cells do not have them?

chloroplasts plant's way of making energy. plants autotrophs, meaning obtain energy food make themselves. obviously, unlike animals, plants can't eat other organisms, need chloroplasts produce energy-rich nutrients.

animals take in nutrients through eating. glucose major nutrient provides energy animals (and other organisms well). glucose molecule broken down in cell's cytoplasm , mitochondrion, releasing energy.

plants, on other hand, build glucose sunlight through process called photosynthesis. chloroplasts contain green pigment chlorophyll, why plant leaves green. chlorophyll absorbs sunlight, source of energy. water taken in through roots , carbon dioxide absorbed air combines make glucose molecule , oxygen (a waste product).

animals don't need this, can eat other organisms contain nutrients glucose, , we're set.
