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 transÂported across the membranes in uncharged state. For uncharged solutes (non-electrolytes), their movement across the membrane depends upon [...]
Let us make an in-depth study of the Mycorrhizae. After reading this article you will learn about their role in absorption of mineral salts by higher plant. The association of a fungus with root of a plant is called as mycorrhiza (plural, mycorÂrhizae). Mycoirhizae play very important and significant role in facilitating absorption of mineral salts by plant roots through [...]
