Question

*State any four differences between prokaryotic cells and eukaryotic cells.

Answer 1

Prokaryotic cell

1. A prokaryotic cell is a primitive type of cell that is characterized by the absence of a nucleus.
2. Furthermore, prokaryotes do not possess membrane-bound cellular organelles.
3. Prokaryotes are exclusively unicellular.

Eukaryotic cells

1. Eukaryotic cells are cells that possess a true nucleus along with membrane-bound organelles.
2. Eukaryotes can either be unicellular or multicellular.

Difference between Prokaryotic and Eukaryotic Cells

	Prokaryotes	Eukaryotes
Type of Cell	Always unicellular	Unicellular and multi-cellular
Cell size	Ranges in size from 0.2 μm – 2.0 μm in diameter	Size ranges from 10 μm – 100 μm in diameter
Cell wall	Usually present; chemically complex in nature	When present, chemically simple in nature
Nucleus	Absent. Instead, they have a nucleoid region in the cell	Present
Ribosomes	Present. Smaller in size and spherical in shape	Present. Comparatively larger in size and linear in shape
DNA arrangement	Circular	Linear
