Cells without nucleoli die because they do not possess:
Correct answer: D. Ribosomes, and are unable to manufacture proteins
- A. Centrioles, and are unable to undergo cell division
- B. Lysosomes, and are unable to destroy worn-out organelles
- C. Mitochondria, and are unable to obtain energy
- D. Ribosomes, and are unable to manufacture proteins
Explanation
Cells without nucleoli die because they do not possess ribosomes, and are unable to manufacture proteins. Ribosomes are the protein factories of the cell. They are made up of RNA and protein, and they are responsible for translating the genetic information in DNA into proteins. Without ribosomes, cells are unable to synthesize proteins, which are essential for all cellular functions.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
