RIBOSOMES
Discovery ->
➡Claude and named it microsome.
actually he discovered fragments of rough endoplasmic reticulam.
➡Robson and Brown 1st discovered ribosome in plant cell.
➡Palade 1st discovered ribosome in animal cell and hence ribosome is called.
Occurence ->
➡ Ribosomes are present in all type of cells.
➡Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
Difference between prokaryot and eukaryot on the basis of ribosomes present in it.
Prokaryot ->
➡In the Prokariyotic cells ribosomes are scattered in cytoplasm and attracted to plasma memebrane.
Eukaryot ->
➡In the eukaryotic cells ribosomes are present on the nuclear membrane.
➡ It also present in the cytoplasm.
➡ In rough endoplasmic raticulam .
➡ In chloroplast and mitochondria.
Main Functions of Ribosomes
➡ It helps in protein synthesis.
