Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle is missing from a cell that is a prokaryote?
A
vacuole
B
nuclei
C
mitochondria
D
chloroplasts
Explanation: 

Detailed explanation-1: -Organelles that are bound to membranes are absent from the nucleus of prokaryotic cells. A prokaryotic cell lacks the nuclear membrane.

Detailed explanation-2: -Prokaryotes do not have membrane-bound organelles, so they would not have mitochondria. Cell walls and plasma membranes are found in both bacteria (prokaryotes) and plants (eukaryotes).

Detailed explanation-3: -Hint: Prokaryotes lack a distinct nucleus (where DNA and RNA are stored in eukaryotic cells), mitochondria, the ER, the Golgi apparatus, and other structures. Prokaryotic cells lack a cytoskeleton in addition to lacking organelles.

Detailed explanation-4: –Cell organelle: In prokaryotic cell, cytoplasm do not have organelle except ribosomes while on the other hand Eukaryotic cell, Cytoplasm contain endoplasmic reticulum, mitochondria, golgi bodies, centrosome, microtubules, microbodies, lysosomes, and also ribosomes. So, the correct answer is Ribosomes.
