Why Do Animals Not Have Chloroplasts
Photosynthetic protist cells also have chloroplasts or the organelles that are able to capture the energy from sunlight and turn it into sugars.
Why do animals not have chloroplasts. They directly or indirectly depend on plant for food. 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. 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.
However plant cells and animal cells do not look exactly the same or have all of the same organelles since they each have different needs. Animal cells do not have chloroplasts. Both plant and animal cells are eukaryotic so they contain membrane-bound organelles like the nucleus and mitochondria.
Plants cells use photosynthesis from the sun which requires them to have chloroplast filled with chlorophyll to complete this function. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. Why do plant cells have chloroplasts and cell walls.
Animal cells do not have chloroplasts. 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. Then explain why the evidence supports your claim.
Why do plant cells have chloroplasts and animal cells do not. Animal cells dont have chloroplasts because animals arent green plants. 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.
These cells also have many chloroplasts in order to trap as much light as possible. So the answer is no. Plant cells have a cell wall chloroplasts and other specialized plastids and a large central vacuole whereas animal cells do not.
