CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which features do prokaryotes not have that eukaryotes do?
A
Nucleus and Genetic Information
B
Membrane-bound organelles and Genetic material
C
Cell Wall and Ribosomes
D
Membrane bound organelles and Nucleus
Explanation: 

Detailed explanation-1: -In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus. The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.

Detailed explanation-2: -Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface.

Detailed explanation-3: -Prokaryotes are organisms whose cells lack a nucleus and other organelles.

Detailed explanation-4: -In prokaryotes, DNA is found in a central area of the cell known as the nucleoid, which is not surrounded by a nuclear membrane. Thus, Prokaryotic cells do not contain membrane-bound organelles.

Detailed explanation-5: -The organelles that eukaryotic cells have and are not found in prokaryotic cells are Chloroplasts, Mitochondria, Endoplasmic Reticulum, Lysosomes, Golgi apparatus. Eukaryotes have a complex body design compared to prokaryotes.
