Step by step
Solved in 1 steps
- briefly comment on the usefulness of tissue analysis in the diagnosis in plant nutrient statusState three moistures condition for determining soil consistenceDescribe how the water potential of a leaf changes throughout the course of a 24-hour period. What is driving this change? How does the water potential of this leaf compare to the water potential of a root in the same plant during the same period? How does it compare to the soil underneath the plant? Please fast and properly explain.
- Which the following statement is FALSE:?a. Relative water content is not a very sensitive index because leaves can show strong responses to <2% change in RWCb. Relative water content is not a very sensitive index because it gives no information about the forces for water movementc. Relative water content is equal the ratio of the mass of water in a given leaf over the mass of water when that leaf was fully saturatedd. Relative water content is equal the ratio of the mass of water in a dry leaf over the mass of water when that leaf was fully saturatedWater potential is a driving force in plants’ ability to transport water. Explain what water potential is, and describe a specific example of its role in water movement throughout a plant.of this practice with respect to plant nutrition?3. WHAT IF? How would adding clay to loamy soil affectcapacity to exchange cations and retain water? Explain.
- Section E. Estimation of the Water Potential (Ψw) of Storage Tissue by Volume Change Method pls answer tysm!state about the Opening and Closing of Stomata ?Select the correct answer regarding cation exchange and plant mineral nutrition cation exchange is necessary because negatively charged ions are stuck to inorganic particles of soil cations are likely to leech out of the soil if there are drainage problems or flooding hydrogen ions freely diffuse out of plant roots into soil cation exchange works because plants substitute a strongly charged cation (H+) for required minerals waste products from cellular respiration provide an energetically free (no ATP needed) mechanism to exchange cations
- Explain why soil water potential is a better measure of water availability for plants than volumetric or gravimetric water content.In a paragraph or two, explain how water and minerals are transported in vascular plants, from the soil to the roots to the rest of the plant. Use precise, correct terminology throughout your essay.Match the following: Zinc Calcium Nitrogen Phosphorous Copper 1. Overall growth and chlorophyll structure. 2. Reproduction and root metabolism. 3. Root and flower growth. 4. Cell wall and overall strength. 5. Regulation of plant growth.
