Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is an organelle that prokaryotes have?
A
Nucleus
B
Ribosomes
C
Mitochondria
D
Lysosome
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Mitochondria and vacuoles’.

Detailed explanation-2: -Ribosomes have RNA and protein. They are sites of protein synthesis. The only cell organelle seen in a prokaryotic cell is the ribosome. Ribosomes in prokaryotes are of the 70s type.

Detailed explanation-3: -All prokaryotes have 70S (where S=Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits. Ribosomes play a key role in the catalysis of two important and crucial biological processes.

Detailed explanation-4: -Prokaryotic Cells do not have any membrane bound organelles, so no nucleus, mitochondria, nor chloroplasts. They have a cell wall, cell membrane, nucleoid, ribosomes, and cytoplasm.

Detailed explanation-5: -Answer and Explanation: The organelles found in prokaryotes are the cytoplasm, ribosomes, cell membrane and cell wall. Bacteria may also sometimes have cilia or flagella but these are not always present.
