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: -Unlike eukaryotes, prokaryotes have no membrane-bound organelles. This means that they lack a nucleus, mitochondria, and other advanced cell structures. All cells rely on protein components in order to function. Protein synthesis takes place on ribosomes, which can be found in all cell types.

Detailed explanation-3: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Detailed explanation-4: -Proteins would not be made. All the organelles would bump into each other and they would not be held in place. Waste would accumulate in the cell (there’d be an excess of worn out organelles, food particles, and engulfed viruses or bacteria).
