The chart below shows the three main types of plant tissues and associated tissues. mc003-1.jpg which row (a, b, c, or d) best completes the chart above? 1 2 3 4 5 a vascular xylem parenchyma phloem sclerenchyma b xylem phloem vascular sclerenchyma parenchyma c parenchyma vascular xylem phloem sclerenchyma d vascular sclerenchyma parenchyma xylem phloem a b c d mark this and return

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

i don't know, but does anyone wanna be friends? i'm doing my homework at 1: 49 in the morning : /
