Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is found in eukaryotic cells but NOT prokaryotic cells?
A
Cell membrane
B
Mitochondria
C
Ribosomes
D
DNA
Explanation: 

Detailed explanation-1: -Prokaryotic cells lack true nucleus as well as membrane bound organelles. Nucleus and membrane bound organelles are present only in eukaryotic cells. Endoplasmic reticulum (ER), the golgi complex, lysosomes, mitochondria, microbodies and vacuoles, etc.

Detailed explanation-2: -Do prokaryotes have mitochondria? No, prokaryotes do not have mitochondria. Mitochondria are only found in eukaryotic cells. This is also true of other membrane-bound structures like the nucleus and the Golgi apparatus (more on these later).

Detailed explanation-3: -Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes.

Detailed explanation-4: -Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

Detailed explanation-5: -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.
