Potassium is a simple, soluble element, important for plants as well as animals. In fact, practically every living thing needs potassium to survive.
Plants use potassium in four important ways:
- Gas exchange – (Allowing plants to open tiny ports “holes” in the surface of the leaves to allow gas to enter and exit the plant)
- Signaling – (Plants uses potassium to communicate between the different cells and parts of the plant. Coordinating growth, reproduction and defenses to diseases and pest)
- Building proteins – (Potassium is important building proteins, which is very important for plant survival.
- Water movement – (Control the osmotic potential of plant cells – Allows the plant to keep its tissues full of water, which is important as plants are made mostly of water)
