Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A mitochondria is bound by a membrane. Do prokaryotic cells contain mitochondria?
A
Yes
B
No
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane. Some researchers have suggested that mitochondria might actually be one of the reasons that eukaryotic cells are typically larger than prokaryotes and more varied in their shape and structure.

Detailed explanation-2: -Prokaryotes lack mitochondria and instead create energy molecules (ATP) on the surface of their cell membrane. A single-celled creature without a nucleus and other membrane-bound organelles is known as a prokaryote.

Detailed explanation-3: -Prokaryotes, on the other hand, don’t have mitochondria for energy production, so they must rely on their immediate environment to obtain usable energy. Prokaryotes generally use electron transport chains in their plasma membranes to provide much of their energy.

Detailed explanation-4: -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-5: -Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.
