Why Do Animals Not Have Chloroplasts
Animal cells do not have chloroplasts.
Why do animals not have chloroplasts. There are photosynthetic animals. Support your claim with evidence from the article. So the answer is no.
Animal cells dont have a dividing cell wall like plant cells do but both do have plasma membranes. Prokaryotes do not have mitochondria or chloroplasts and they generally possess internal membrane systems that are far less complex than those found in the eukaryotes. Chloroplasts are found only in plant cells because they contain a green pigment called chlorophyll.
Animals do not need to get energy by photosynthesis as they can take in food directly so they do not need chloroplasts. Plants cells use photosynthesis from the sun which requires them to have chloroplast filled with chlorophyll to complete this function. Like mitochondria chloroplasts have their own DNA.

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.
Plant cells have chloroplasts but animal cells do not. Consider that plants maximize their surface area to the extent possible for a living organism and still only have enough energy to grow and reproduce - movement is essentially impossible. Plant cells have chloroplasts but animal cells do not.
Similarly it is asked why don t animal cells have cell walls and chloroplasts. Chloroplasts are organelles or small specialized bodies in plant cells that contain chlorophyll and help with the process of photosynthesis. Animal cells each have a centrosome and lysosomes whereas plant cells do not.
