Detailed explanation-1: -Animals don’t need chloroplasts because they acquire sugar from their diet; they just need mitochondria. Vacuoles are found in both plant and animal cells. A big, solitary vacuole is found in each plant cell and is used to store water and nutrients.
Detailed explanation-2: -Plant Evolution – “Living on borrowed plastids” Plastids containing chlorophyll, the green pigment that captures light for photosynthesis, are called chloroplasts. Humans can’t make plastids – we don’t have the genes for it.
Detailed explanation-3: -Humans cannot make their own food because we do not have things that plants have such as chlorophyll. The carbon dioxide and water are transformed into a totally new substance that contains energy–it is food in the form of sugar.
Detailed explanation-4: -Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
