Question

The only one cell organelle seen in prokaryotic cells,
A) Mitochondria
B) Plastid
C) Ribosomes
D) Lysosomes

Answer 1

Hint: Prokaryotic cells are those which contain a primitive or not developed nucleus.

Complete Answer:
1) The major difference between prokaryotic cells and the eukaryotic cell is the nucleus. Eukaryotic cells contain a well-developed nucleus and double-membrane bound cell organelles, on the other hand, prokaryotic cells do not contain double-membrane bound cell organelles. But ribosomes are found in both types of cells.

2) Mitochondria is a very small organelle that you can view with the help of a microscope only. You can say it is the powerhouse of the cell. It helps in the production of adenosine triphosphate (ATP). ATP is also called the energy currency for different cellular processes.

3) Plastids are doubled membraned organelles that you can find in the plant cells. It plays a vital role in the manufacturing or storage of the plant’s food. It includes chloroplasts, chromoplasts as well as leucoplasts.

4) Lysosomes are subcellular organelles that can be found in most of the animal cells. It contains hydrolytic enzymes that can decompose excess of all sorts of biological polymers.

So, ‘ribosomes’ is the correct answer.

Additional information: Ribosomes are responsible for protein synthesis., that’s why these are called protein-factory of the cell.

Note: Internal membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, plastids, vacuoles, and lysosomes are absent in prokaryotic cells.
