Question

Why chloroplast, chromoplast and chromoplast consider living components of plant cell while crystals, starch grains and aleuronic grains consider non-living components

Answer 1

The chloroplast and chromoplast considered the living components of plant cell because of their respective functions. The chloroplast is used for photosynthesis while the chromoplasts are responsible for the distinctive pigment in plants.

Whereas the crystals, starch grains and aleuronic grains consider non-living components because they do not carry such functions. The starch granules store some of the food made during photosynthesis.
