Question

What are the parts and function of a prokaryotic cell?

Answer 1

Prokaryotic cell:

1. Prokaryotic cells lack a true nucleus and organelles that are membrane-bound.
2. Prokaryotic cells are single-celled microorganisms that are thought to be the oldest on the planet. Bacteria and Archaea are examples of prokaryotes.
3. Cyanobacteria are photosynthetic prokaryotes that perform photosynthesis.
4. Prokaryotic Cell Characteristics:
   1. They do not have a nuclear membrane.
   2. There are no mitochondria, Golgi bodies, chloroplasts, or lysosomes.
   3. The genetic material is only found on one chromosome.
   4. They lack histone proteins, which are essential components of eukaryotic chromosomes.
   5. The plasma membrane serves as the mitochondrial membrane, which transports respiratory enzymes
5. Prokaryotic cells are made up of four major components:
   1. Plasma Membrane: The plasma membrane is an outer protective layer of phospholipid molecules that separates the cell from its surroundings.
   2. Cytoplasm: Cytoplasm is a jelly-like substance found inside cells. It contains all of the cell organelles suspended in it.
   3. Ribosomes: Protein synthesis takes place here.
   4. DNA: It is the cell's genetic material. Circular DNA is found in all prokaryotes. It controls which proteins are produced by the cell. It also controls the cell's actions.
