Answer 1

It's so long......................
And 22 )- cytoplasm.

Answer 2

ANS 14)







AnS 31 .. lipids get synthesised in smooth endoplasmic reticulum constituting the plasma membrane.

protein get synthesised in rough endoplasmic reticulum because it contains ribosomes constituting the plasma membrane.
