Question

Prokaryotic cells are characterised by

• A. Absence of nuclear envelope
• B. Presence of nuclear envelope
• C. Presence of distinct chromosome
• D. Absence of chromatin material

Answer 1

Answer: (A)

Prokaryotic cells are unicellular organisms that lack membrane-bound organelles such as mitochondria, Golgi complex. They also lack a true nucleus. The genetic material is not surrounded by a nuclear envelope. The genetic material without the nuclear envelope is called as the nucleoid. Example of a prokaryotic cell is bacteria.

Thus, the correct answer is 'Absence of nuclear envelope.'
