Chloroplasts
a. move complex sugars through the cell membrane
b. store water
c. control cellular activities
d. absorbs light in photosynthesis

Option D

Explanation:

Chloroplast is a cell organelle which is found specifically in the plant cell. It stores pigment named as chlorophyll.

This pigment traps the sunlight which is used for the process of photosynthesis.

In the process of photosynthesis the light energy that is trapped in the chloroplast is converted into chemical energy.

This energy is used for the various metabolic processes in plant cell.

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

it takes hundreds of years to become stable.
