NEET BIOLOGY

Detailed explanation-1: -Then there’s the smooth endoplasmic reticulum, which doesn’t have those ribosomes on it. And that smooth endoplasmic reticulum produces other substances needed by the cell. So the endoplasmic reticulum is an organelle that’s really a workhorse in producing proteins and substances needed by the rest of the cell.

Detailed explanation-2: -Researchers have uncovered the mechanism that cells use to find and destroy an organelle called mitochondria that, when damaged, may lead to genetic problems, cancer, neurodegenerative diseases, inflammatory disease, and aging.

Detailed explanation-3: -Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.

Detailed explanation-4: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.
