NEET BIOLOGY

Detailed explanation-1: -Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.

Detailed explanation-2: -Ribosomes are found in both prokaryotic and eukaryotic cells.

Detailed explanation-3: -Ribosomes found in eukaryotic organelles such as mitochondria or chloroplasts have 70S ribosomes-the same size as prokaryotic ribosomes. However, outside of those two organelles, ribosomes in eukaryotic cells are 80S ribosomes, composed of a 40S small subunit and a 60S large subunit.

Detailed explanation-4: -The eukaryotic cells generally contain the 80S type of ribosome in the endoplasmic reticulum and as free ribosome in the cytoplasm.
