EVERYDAY SCIENCE

Detailed explanation-1: -Animals don’t need chloroplasts because they acquire sugar from their diet; they just need mitochondria. Vacuoles are found in both plant and animal cells. A big, solitary vacuole is found in each plant cell and is used to store water and nutrients.

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: -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-4: -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-5: -Animals are mobile organisms, which means that they can move around to obtain their food. They can fulfill their nutritional requirement by preying or obtaining food from other sources. Therefore, they do not require any pigments which help in synthesising food through photosynthesis.
