Question

Eukaryotic cells are different from prokaryotic cells in having

• A. True nucleus
• B. Ribosomes
• C. Mitochondria in mesosome form
• D. Only smooth endoplasmic reticulum

Answer 1

The correct option is A True nucleus

• Eukaryotic cells have a true nucleus whereas prokaryotic cells have a primitive nucleus.
• The true nucleus of eukaryotes is a double membrane-covered protoplasmic body that contains hereditary information.
• A true nucleus is made up of five parts- nuclear envelope, nucleoplasm, nuclear matrix, chromatin, and nucleolus.
• The primitive nucleus of a prokaryote is also called as nucleoid as it lacks these parts. It is comprised of only the genetic material. So, option A is correct.
