Question

Which of the following statements is correct?

• A. Eukaryotic cells multiply rapidly than prokaryotic cells
• B. The nucleolus is present in prokaryotic cells
• C. Membrane-bound organelles are absent in prokaryotic cells
• D. 80S ribosomes are present in bacterial cells

Answer 1

The correct option is C Membrane-bound organelles are absent in prokaryotic cells

Prokaryotic cells multiply rapidly than eukaryotic cells due to their simple structures and usually smaller genomes. Prokaryotic cells lack a well-defined nucleus and membrane-bound cell organelles. They have a DNA which is circular and contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. The nucleolus is the distinct structure present in the well-defined nucleus of eukaryotic cells. The nucleolus is absent in prokaryotic cells.
Prokaryotic cells have 70S ribosomes and 80S ribosomes are found in eukaryotic cells.
