1 In Photosynthesis, potassium regulates the opening and closing of stomata, and therefore regulates CO2 uptake. 2  Potassium triggers activation of enzymes and is essential for production of Adenosine Triphosphate (ATP). 3  ATP is an important energy source for many chemical processes taking place in plant issues. Protein and starch synthesis in plants require potassium as well. 2  Potassium is essential at almost every step of the protein synthesis. 3  In starch synthesis, the enzyme responsible for the process is activated by potassium.
In the leaves of a plant is a substance called chlorophyll. Chlorophyll makes leaves green. It also traps the energy from the sun so the plant can use it. When plants take carbon dioxide from the air, they release oxygen. Animals use this oxygen to grow. We release carbon dioxide, which the plants use. Plants also need minerals from the soil to grow. Nitrogen helps them grow and make leaves. Phosphorus helps grow strong roots. Potassium helps the plant make fruit and it keeps them healthy. Plants need large amounts of nitrogen, phosphorus and potassium. The soil doesnât always have enough of these nutrients. Gardeners use fertilizer to give plants more nutrients. Fertilizers are sort of like vitamins for plants.
