more about Ribosomes :-
☆ Ribosomes are the granual structures first observed under the electron microscope as dense particles by George Palade in 1953 .
☆ Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
☆ they are composed of RNA and proteins and are not surrounded by any membrane.
☆ the eukaryotic ribosomes are 80 S while the prokaryotic ribosomes are 70 S .
☆ each ribosome has two subunits ,
- larger ( 80 S having 60 S and 40 S ) .
- smaller ( 70 S having 50 S and 30 S ) .
☆ here , 'S' ( Sandberg's unit ) stands for the sedimentation constant .

Notes on Ribosomes ??
AnsweR:
Ribosomes are complex cell organelles made of RNA and protein that translates genetic code into chains of amino acids.
The ribosome is a complex molecular machine found inside the living cells.✔️✔️✔️
Ribosomes are special organelles as they are found in both prokaryotic and eukaryotic cells.
Ribosomes Structure :-
A ribosome is a complex of RNA and protein and is, therefore, known as a ribonucleoprotein.
