Which organelle is missing in prokaryotic cells?
A
nucleus
B
DNA
C
ribosomes
D
plasma membrane
Explanation: 

Detailed explanation-1: -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: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-4: -By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid.
