Ans - Endoplasmic Reticulum
23) If Ribosomes Of The Cell Are Destroyed Then -
Ans - Protein Will Not Form
RIBOSOMES -
> Red In Colour
> Located In Endoplasmic Reticulum
> Autophagy During Nitrogen Starvation Destroy Ribosomes
> Two Types Of Ribosomes a) 70s and b) 80s
> FUNCTIONS -
> A Ribosome Is An Intercellular Structure Made Up Of Both RNA And Protein.
> It Is The Site Of Proteins Synthesis In The Cell
> It Reads The mRNA Sequence And Translates The Genetic Code Into Specified String Of Amino Acids , Which Grow Into Long Chain That Fold To Form Proteins.

Ans - Mitosis
SOMATIC CELL - The Cells In The Body Other Than Sperm And Egg Cells
eg - RBC Is a Somatic Cell
MITOSIS -
> The Process Of Cell Division Where In The Chromosomes Replicate And Get Equally Distributed Into Two Daughter Cells ( Diploid)
> Mitosis Is Also Known As Equational Division.
MEOISIS -
