WebMost of the ions such as Na, K, and other are bound to colloidal soil particles. Root cells secrete hydrogen ions which are positively charged. Such ions can easily displace cat ions like K+, Na+ ions that are bound to clay particulates. Thus the cat ions are made available for root system to absorb the required ion. WebRoot hairs are single-celled extensions of epidermis cells in the root They are long and thin so they can penetrate between soil particles and absorb water and minerals from the soil Root hairs increase the surface area to volume ratio which increases the uptake of water and mineral ions nottingham gum clinic wa
