Fundamentally its because animals are descended from unicellular eukaryotes that never acquired chloroplasts probably because the split between animals and plants occurred before the plant ancestors formed an endosymbiotic relationship with cyanobacteria.
The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plant cells have chloroplasts but animal cells do not. Animal cells do not have chloroplasts.
Similarly it is asked why don t animal cells have cell walls and chloroplasts. Animal cells dont contain chloroplasts because they do not produce their own food. I believe the gist of it is that chloroplasts simply cannot create enough sugar from photosynthesis to significantly power the energy-intense needs of any but the simplest of animals.

Plants produce their own food via photosynthesis because they are at the bottom of the food chain - they are the producers whereas animals eat either plants or other animals. Leave a Reply Cancel reply. Which protist does not have mitochondria.
