While surveying his apple trees, a farmer discovers a particular tree that produces apples with perfect size, color, and flavor. to reproduce this plant, he removes a twig from the s tree and attaches it to the stem and root system of a growing apple tree in a process called grafting. the tree will continue to grow and will later produce apples.
why does he use this method instead of planting an apple seed from the tree with ideal apples?

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
