The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

Okay so there are two types of ERs, smooth and rough.
Rough endoplasmic reticulum contain ribosomes on the outer surface. It provides large surface area for proteinsynthesis and the synthesis of glycoproteins and also provides a pathway for the transport of materials.
Smooth ER synthesises, stores and transports lipids and carbohydrates.
Hope this helps
