Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Prokaryotes do not have a nucleus. Which of the following organelles is also NOT found in a prokaryote?
A
cell wall
B
ribososme
C
flagellum
D
mitochondria
Explanation: 

Detailed explanation-1: -Thus, the correct answer is ‘Mitochondria. ‘

Detailed explanation-2: -A prokaryotic cell lacks the nuclear membrane. The double membrane layer that encircles the nucleus is known as the nuclear membrane.

Detailed explanation-3: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane. Instead, the DNA simply exists in a region of the cell called the nucleoid. Prokaryotic cells only have a small range of organelles, generally only a plasma membrane and ribosomes.

Detailed explanation-4: -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-5: -The ribosome is the only organelle that can be seen in both prokaryotic and eukaryotic cells.
