Question

I am present on the surface of a single
membranous organelle ‘A’ and also inside the
double membrane bound organelle ‘B’. Who I
am, name the organelles ‘A’ and ‘B’
respectively
1) lysosomes, endoplasmic reticulum and
nucleus
2) ribosome, smooth endoplasmic reticulum
and mitochondria
3) lysosomes, golgi bodies and nucleus
4) ribosome, rough endoplasmic reticulum and
mitochondria​

Answer 1

Answer:

4) ribosomes, rough endoplasmic reticulum and mitochondria

Explanation:

Ribosomes are present on the surface of single membranous organelle ' rough endoplasmic reticulum' and also inside the double membrane bound organelle ' mitochondria'.

i.e. the answer is ribosomes

and 'A' = rough endoplasmic reticulum

and 'B' = Mitochondria
