Prokaryotic Cell

1. What is a Prokaryotic Cell?

A prokaryotic cell lacks a true nucleus and membrane-bound organelles. It comprise bacteria and archaea that are characterized by a simple structure with a cell wall, nucleoid, and plasma membrane.

2. What are the Structural Features of Prokaryotic cells?

Prokaryotic cells lack a true nucleus and membrane-bound organelles and contains genetic material in a nucleoid. It have a cell wall, plasma membrane, ribosomes, and may contain flagella, pili, and sometimes a protective capsule or slime layer.

3. How do Prokaryotic cells divide?

Prokaryotic cells divide through binary fission and the cell’s DNA replicates and splits into two genetically identical daughter cells. This asexual mode of reproduction is characteristic of bacteria and archaea.

4. What is the difference between Prokaryotic and Eukaryotic cells?

Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and membrane-bound organelles.

5. Why is the process of cell division in prokaryotic cells different from that in eukaryotes?

The process of cell division in prokaryotic cells is different from eukaryotes because prokaryotes lack a defined nucleus and complex organelles, and their cell division, called binary fission, is a simpler, asexual process without mitosis or meiosis.

Prokaryotic Cells

Prokaryotic cells are single-celled organisms that lack a true nucleus and membrane-bound organelles. Their genetic material is present in a nucleoid region. They are normally smaller than eukaryotic cells, with a size range of 0.1 to 5 μm in diameter. Prokaryotic cells for example bacteria and archaea have a cell wall and fimbriae and pili can often be found on the surface of bacterial cells. They evolved before the eukaryotic cells and live in nearly all environments on Earth. They have the ability to adapt to diverse environments.
