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.
