Why are the products of the light reaction of photosynthesis important? a)  they are used to produce sugar during the dark reaction. b)    they are used to split excess water in the cell. c)    they are used to build membranes and other cell structures. d)    they are used to generate large amounts of atp in the dark reaction.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the correct answer in apex is tissue development, i know because i just had this question
