Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves, Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each trait, and then
create your simulation. Be sure to include a key that states the color coding for each trait.

I don´t know if this is right, but this is what I got.  

Explanation:

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
