If pressure goes up and temperature remains the same, what happens to volume ?

the answer is d (apex) good luck : ))

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.

"a.) well–developed vascular system."
