Which of the following organelles is smallest in size?a)Ribosomeb)Mitochondrialc)Chloroplastd)LysosomeCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Ribosomes are also known as the powerhouse of the cell they are used for the protein synthesis and plays a vital role in acquiring energy in the form of adenosine triphosphate, adenosine diphosphate and Nicotinamide adenine dinucleotide phosphate so it is very important but space managing is also very important and it has some structures found in It known as Cristaewhich increases the surface area and the amount of energy released.

Answer

Ribosomes
Because this helps in protein synthesis and is present in endoplasmic reticulum i.e. Rough Endoplasmic reticulum

Answer

A

Answer

Ribosomes are primary site of protein synthesis or translation and measure 20 nm.
Lysosomes or "suicidal bags" of the cell measure 200 nm.
Mitochondria, the powerhouse of the cell are site of cellular respiration measures 3000 nm
Chloroplast is the site of photosynthesis and measures 5000 nm.
Therefore, ribosomes are smallest of all.

Answer

Smallest Organelle: Ribosome
Ribosomes are the smallest organelles in size among the options given. Here is an explanation of why ribosomes are the smallest organelles:

Structure of Ribosomes:
- Ribosomes are tiny spherical organelles found in both prokaryotic and eukaryotic cells.
- They are composed of a small subunit and a large subunit, which together create a functional ribosome.
- Ribosomes are made up of ribosomal RNA (rRNA) and proteins.

Function of Ribosomes:
- Ribosomes are responsible for protein synthesis in the cell.
- They read the genetic information from messenger RNA (mRNA) and link amino acids together to form a protein chain.

Comparison with Other Organelles:
- Mitochondria and chloroplasts are larger organelles compared to ribosomes. They have their own DNA and are involved in energy production in the cell (ATP synthesis).
- Lysosomes are membrane-bound organelles containing digestive enzymes. They are larger than ribosomes but smaller than mitochondria and chloroplasts.
In conclusion, ribosomes are the smallest organelles in size, but they play a crucial role in protein synthesis, which is essential for the functioning of cells.

Answer

Ribosomes are primary site of protein synthesis or translation and measure 20 nm.
Lysosomes or "suicidal bags" of the cell measure 200 nm.
Mitochondria, the powerhouse of the cell are site of cellular respiration measures 3000 nm
Chloroplast is the site of photosynthesis and measures 5000 nm.
Therefore, ribosomes are smallest of all.
