What are ribosomes in the chapter cell? For class 6 ICSE....give the answer according to that in simple language, Don't give class 8 or class 9 answer PLZ

Answer 1

$\huge{\boxed{\sf{ANSWER}}}$

Ribosomes are the cell organelles found in a cell.

It is the only cell organelles which is found in both Prokaryotic and eukaryotic cells.

It is observed that Ribosomes do not have any outer covering or membrane.

The main function of ribosome is to manufacture proteins in the body of living organisms.

Ribosome also helps during the process of translation while synthesising proteins.

Ribosome is composed of two cap like structure - a larger and a smaller unit. Both of them are attached due to magnesium.

Answer 2

$\huge{ \underline{ \mathfrak{Ribosomes :}}}$

» Ribosomes are the structures than are present on the Rough Endoplasmic Reticulum.

» They make the Rough Endoplasmic Reticulum look rough.

» They are sites for protein and polypeptide production. They consist of RNA.

» They join transfer RNA and messenger RNA

» Ribosomes aren't present in the smooth endoplasmic reticulum.

» They also aren't present in the prokaryotic cells.

» The main function of ribosomes is to make proteins.

» These ribosomes can be found floating in the cytoplasm or can be found attached to the endoplasmic reticulum.

» Ribosomes don't have any outer covering.

» They are mostly found in mitochondria and chloroplasts of eukaryotic cells.

» There are two basic types of ribosomes. One is 70S & 80S
