Which is the BEST explanation why photosynthesis is so important to people and to all life on Earth? a Photosynthesis produces the oxygen and food energy that all non-plant organisms require to survive.

b Only plants (and some bacteria) have chloroplasts and can photosynthesize, which produces oxygen that all non-plant organisms need.
c Plants are the original producers of food for all other life forms; without plant life, there could not be animal life.
d Many people take plants for granted and don’t realize how essential they are, so it is important that photosynthesis take place even when no one notices.

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

meiosis is the correct answer
