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: -Mitochondria and chloroplast are two organelles that have been found in eukaryotic cells. Chloroplast is found only in plants, while most eukaryotic cells have mitochondria. Although both organelles are found in eukaryotic cells, both mitochondria and chloroplast are often found in prokaryotic cells.

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: -Ribosomes are non-membrane bound organelles found in both eukaryotic as well as prokaryotic cells.

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.
