Respuesta :

Since plants and photosynthetic protists do not have the machinery for being heterotroph but they can make their own food in the presence of chloroplast, this is the reason why they possess chloroplast. Animals cells on the other hand cannot perform photosynthesis and hence do not possess chloroplast.

Heterotroph is one of the types of mode of nutrition. In this the organism obtains their food from some other organism that can either be plant or another animal. The example of heterotrophs are all the animals and humans.

Photosynthesis is the process of synthesizing food by capturing the sunlight energy and releasing oxygen as the by-product.
