Question

Which Organelle synthesizes energy?
A. Ribosome
B. Mitochondria
C. Chloroplast
D. Endoplasmic reticulum
E. Golgi apparatus

Answer 1

Hint: Cell organelles as we know are the components of a cell. They are useful for performing different activities of a cell just like the organ system in the body. Cells perform different activities like- cell repair, blood formation, repair damage tissues etc. Cells are the vital structures of life.

Complete answer:
Option A: Ribosome- Ribosome are structures which are composed of ribonucleic acid and proteins and are not surrounded by any membrane. Ribosome’s main functions include protein synthesis as proteins or polypeptides are formed from the surface of the ribosomal membrane. Hence, they are called the protein factory of the cell engine.
Option A is not the correct answer
Option B: Mitochondria- mitochondria is the powerhouse of the cell, as it performs all important functions of the cell. It provides an abundance of energy required for the cell to grow and also in cell repair. It provides energy to sperms also for motility.
Option B is the correct answer.
Option C: Chloroplast- chloroplast is the green pigment of the cell. Mostly chloroplast is present in plant cells, animal cells lack chloroplast.
Option C is not the correct answer.
Option D: Endoplasmic reticulum- endoplasmic reticulum is also a cell organelle. It is present in eukaryotic cells only. It has two types- SER and RER. RER is an abbreviation for a rough endoplasmic reticulum. SER is an abbreviation for smooth endoplasmic reticulum.
Option D is not the correct answer.
Option E: Golgi apparatus- Golgi bodies are densely stained reticular structures near the nucleus. They consist of flat, disc-shaped sacs or cisternae. They are stacked parallel to each other. The Golgi complex has a variety of cisternae.
Option E is not the correct answer.

Hence, Option B is the correct answer.

Note:
As we discussed various organelles. Eukaryotic and prokaryotic organelles are and . ribosomes are the headquarters for the polypeptide synthesis. Hence, polypeptide is the building blocks of our body. And as cells are multicellular structures. So, it helps in all vital components in our bodies.
