Question

How do ribosomes differ from lysosomes?

Answer 1

Hint: Lysosomes helps in storing the digestive enzymes for the protection of cells from bacteria whereas Ribosomes acts as a protein synthesizing machine composed of ribosomal proteins and ribosomal RNAs.

Complete answer:
The ribosome is a multifaceted molecule consisting of ribosomal RNA molecules and protein. It creates a factory for protein synthesis in the cell. Ribosomes are tiny spherical organelles that produce proteins whose amino acids are joined together. In the cytosol, there are many ribosomes which are free and some go to rough endoplasmic reticulum. Ribosomes translate encoded messages from messenger RNA or Mrna to proteins with the help of tRna.
Ribosomes are found in both prokaryotes and eukaryotes. In prokaryotes it is found in cytoplasm and in eukaryotes they are found in the matrix of mitochondria and stroma of plastids.
Lysosomes are membrane bound organelles which helps in the digestion of the cell, when it is inactive or by hydrolytic enzymes. The size of lysosome is mainly $0 \cdot 5$micrometers while the large one is of $1 \cdot 3$micrometers.
The destruction or digestion of lysosomes of enzymes is similar as the food is digested in the stomach. Besides autolysis, lysosomes also help in cell signalling, cell membrane restoration. These cells help in the destruction of any cell debris or other foreign particles called autolysis.

Major differences between Lysosomes and Ribosomes are:

Lysosomes	Ribosomes
Lysosomes occur in the eukaryotic cells.	Ribosomes occur in prokaryotic and eukaryotic cells. In prokaryotes $70$S and in eukaryotes it is $80$ S.
Lysosomes are of $0 \cdot 5$to $1 \cdot 3$micrometers in size.	Ribosomes are tiny in size, mainly $25$nanometers.
Lysosomes are surrounded with the membrane.	Ribosomes do not contain any membrane but during the production of protein it is surrounded by membrane.
Lysosomes are present in the cytoplasm.	Ribosomes are found in the endoplasmic reticulum as well as in the cytoplasm.
Lysosomes are composed of proteins and digestive enzymes.	Ribosomes are composed of ribosomal proteins as well as ribosomal Mrna.
The main function of lysosomes is in the breakage of cells and it removes foreign particles.	The main function of Ribosomes is in the production of proteins and helps in the translation activity.

Note: Lysosomes can destroy the whole cell if they are ruptured and their enzymes are released in the cytoplasm because of this they are called suicidal bags of the cells. It is found that E. coli cells consist of 30,000 ribosomes whereas eukaryotic cells contain up to half a million ribosomes.
