Respuesta :
Answer:
1. Are usually single-celled.
2. Do not contain membrane-bound organelles
3. Have DNA located in cytoplasm
Explanation:
Prokaryotic cells are single-celled organisms which have the following characters:
1. They lack a true nucleus and hence, they do not have their genetic material enclosed in a nuclear membrane-bound nucleus, rather it is present in the cytoplasm.
2. They lack all the membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.
3. They are usually. very small in size and hence are microscopic.
Examples include all the bacterias.
The prokaryotic cell emerged before the eykaryotics. The descriptions that apply are: they are usually single-celled, they do not contain membrane-bound organelles, they have DNA located in cytoplasm
What are the prokaryotic cells?
Prokaryotic cells are a primitive type of cell, that emerged before eukaryotic cells.
The archaea and bacteria domains are composed of prokaryotic unicellular microorganisms.
The prokaryotic cell has few internal structures.
- They lack a nucleus, nuclear membrane, and organelles.
- They only present plasmids and ribosomes.
- Their circular DNA is free in the cytoplasm.
- They have a cell wall that protects the cell, and some of them can also present a capsule.
They reproduce as3xually.
Some of these organisms are restricted to marginal habitats. They are capable of inhabiting in places with extreme temperature, salinity, acidity, or pH, among others.
The descriptions that apply are
- are usually single-celled
- do not contain membrane-bound organelles
- have DNA located in cytoplasm
