Question

Why do plants need potassium?

Answer 1

In Photosynthesis, potassium regulates the opening and closing of stomata, and therefore regulates CO2 uptake. Potassium triggers activation of enzymes and is essential for production of Adenosine Triphosphate (ATP). ATP is an important energy source for many chemical processes taking place in plant issues.

Answer 2

$In \: Photosynthesis, \: potassium \: regulates \: \\ the \: opening \: and \: closing \: of \: stomata, \: and \: \\ therefore \: regulates \: CO2 \: uptake. \: \\ Basically, \: potassium (K) \: is \: responsible \: for \: \\ many \: other \: vital \: processes \: such \: as \: \\ water \: and \: nutrient \: transportation, \: protein, \: and \: \\ starch \: synthesis. \: \:$
