Difference between Lysosome and Ribosome
A cell contains different types of cell organelles which perform different roles within the cell and they help in the survival of living organisms. As cell organelles, lysosomes and ribosomes carry out different functions in the cell. Lysosomes are found only in eukaryotic cells but ribosomes are present in both prokaryotic and eukaryotic cells.
Lysosomes are the membrane-bounded cell organelle which contains different types of digestive enzymes. It is also known as the garbage disposal system of cells which destroy unwanted garbage materials from the cell. Lysosomes are capable of degrading all types of polymers of the cell because they contain an array of digestive enzymes.
Ribosomes are small in the structure which is made up of ribosomal RNA and proteins. It is considered as the protein-synthesizing machines of the cell that synthesize proteins from RNA molecules. The ribosome has two subunits. Prokaryotic cells contain 70S ribosomes which comprise of 50S and 30S subunits. In a eukaryotic cell, ribosomes are the 80S which contain the 40S and 60S subunits. The difference between ribosome and lysosome are stated in the following table:
The lysosome is present in the cytoplasm of the eukaryotic cell only.
The ribosome is present in the cytoplasm of both prokaryotic and eukaryotic cell.
The lysosome is larger in size than ribosome which ranges from 0.1 to 1.2 µm.
Ribosomes are typically smaller in size than lysosome which ranges 20 to 30 nm.
It is covered by a unit membrane i.e., it is membrane-bound organelle.
It is not covered by the membrane i.e., it is non-membranous organelle.
These are evenly and freely distributed throughout the cytoplasm.
These are freely distributed throughout the cytoplasm as well as these remain attached with the membrane of the endoplasmic reticulum etc.
It consists of a single part.
It consists of mainly two parts.
It is a minute spherical vesicle filled with hydrolytic enzymes and small vesicles.
It is a minute spherical structure of ribonucleoprotein and contains no vacuoles.
It always remains separate from each other.
Ribosomes are grouped together during protein synthesis and forms polyribosome.
Functionally it is of four types; Primary lysosome, secondary lysosome, residual body, and autophagosome.
According to size, the ribosomes are two types; 80S and 70S.
It is responsible for digestion of protein along with other substances of the cell.
It is responsible for the digestion of protein synthesis.
It is discovered by Cristian De Duve
It is discovered by George E. Palade.
It is made up of digestive enzymes and membrane proteins.
It made up of ribosomal RNA and ribosomal proteins.
The lysosome contains a vast array of enzymes.
It does not contain an enzyme.
