Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Both prokaryotic and eukaryotic cells contain all of the following EXCEPT
A
Cell (Plasma) Membrane
B
Chloroplast
C
Cytoplasm
D
Ribosomes
Explanation: 

Detailed explanation-1: -Prokaryotic cells do not have chloroplasts as it consists of lipid membranes. This makes it a membrane-bound organelle, which is exclusive to eukaryotes. . However, prokaryotes such as cyanobacteria contain a type of chlorophyll called chlorophyll-a.

Detailed explanation-2: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-3: -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-4: -In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.
