- the presence of distinct chromosome
- absence of nuclear membrane
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Prokaryotic cells are characterised by naked genetic material without being organised into a nucleus, a single envelope organisation, absence of spindle apparatus, meiosis and sexual reproduction.

Concepts Used:
Prokaryotic Cells
Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis.
A prokaryotic cell contains a single membrane and therefore, all the reactions occur within the cytoplasm. They can be free-living or parasites.
Characteristics of Prokaryotic Cell:
Prokaryotic cells have different characteristic features such as:
- Lack of a nuclear membrane.
- Absence of Mitochondria, Golgi bodies, chloroplast, and lysosomes.
- Presence of genetic material on a single chromosome.
- Lack of histone proteins in the constituents of eukaryotic chromosomes.
- The cell wall is made up of carbohydrates and amino acids.
- The plasma membrane acts as the mitochondrial membrane carrying respiratory enzymes.
