Where do we find most of our usable freshwater, and what can we do to keep it clean.

we find most of our cleanest water in freshwater rivers and lakes and we keep it clean by using processing plants

are there any answer choices

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.
