Let us make an in-depth study of the mechanism of absorption of mineral salts from soil by plants. Mechanism of Mineral Salt Absorption: Previously, it was thought that the absorption of mineral salts from the soil took place along with the absorption of water but it is now well established that the mineral salt absorption and water absorption are two [...]
The following points highlight the six factors affecting absorption of mineral salt in plants. The factors are: 1. Temperature 2. Hydrogen Ion Concentration 3. Light 4. Oxygen Tension 5. Ion Interaction and 6. Growth. Factor # 1. Temperature: Generally, an increase in temperature up to a certain limit brings about an increase in rate of salt absorption. However, this effect [...]
Let us make an in-depth study of the modern view of solute transport across membranes in plant. The mineral salts are absorbed by plants in their ionic form and so is their transport within plants. Certain solutes such as sugars are however transported across the membranes in uncharged state. For uncharged solutes (non-electrolytes), their movement across the membrane depends upon [...]
