GENERAL HISTOLOGY

Detailed explanation-1: -Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria. Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell.

Detailed explanation-2: -What Cells Lack Chloroplasts? The inner stem cells and underground organs, such as the root system or bulb, contain no chloroplasts. Because no sunlight reaches these areas, chloroplasts would be useless.

Detailed explanation-3: -Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia.

Detailed explanation-4: -It is a common perception that animal cells do not have chloroplasts, the organelles that performs photosynthesis. Yet, a small number of sea slugs are able to incorporate carbon from CO2 by performing photosynthesis using sequestered chloroplasts from the macroalgae in their diet.

Detailed explanation-5: -Chloroplasts contain green pigment called chlorophyll which helps in manufacture of food through the process of photosynthesis. Since, animals do not manufacture food so they do not need chloroplast. And hence, chloroplast is found only in plant cell.
