Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following lists structures shared by BOTH prokaryotes & eukaryotes?
A
cell wall, cytoplasm, genetic material, nucleus
B
cytoplasm, genetic material, cell wall, ribosomes
C
nucleus, mitochondrion, endoplasmic reticulum, chloroplasts
D
ribosomes, golgi apparatus, cytoplasm, cell wall
Explanation: 

Detailed explanation-1: -Ribosomes are the smallest cell organelles which can be seen only through an electron microscope. They are found in both prokaryotic as well as eukaryotic cells. Ribosomes are dense, round bodies which occur freely in the cytoplasm and may remain attached to the surface of the endoplasmic reticulum.

Detailed explanation-2: -Both prokaryote and eukaryote cells have a cell membrane. This is a lipid bilayer that keeps the contents of the cell in and keeps unwanted substances out. The membrane controls the movement of substances into and out of the cell. The material inside both types of cells is called the cytoplasm.

Detailed explanation-3: -All prokaryotic and eukaryotic cells have some similar features as they both contain ribosomes, genetic material, a cytoplasm, and plasma membranes.

Detailed explanation-4: -Ribosomes are the cellular organelles that carry out protein synthesis. They are found in both prokaryotes and eukaryotes.

Detailed explanation-5: -One major component of the cytoplasm in both prokaryotes and eukaryotes is the gel-like cytosol, a water-based solution that contains ions, small molecules, and macromolecules. In eukaryotes, the cytoplasm also includes membrane-bound organelles, which are suspended in the cytosol.
