Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Prokaryotes have contains membrane-bound organelles. True or False?
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Prokaryotic cells do not contain a well-defined nucleus or any other membrane-bound organelle.

Detailed explanation-2: -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-3: -Prokaryotic cells only have a small range of organelles, generally only a plasma membrane and ribosomes. Eukaryotic cells, on the other hand, have chromosomes that are enclosed in a true nucleus, and are therefore separated from the cytoplasm by the nuclear membrane.

Detailed explanation-4: -Prokaryotic cells do not contain membrane-bound organelles.

Detailed explanation-5: -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. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid.
