How would you assess leaf water potential? Explain the principle of the method and describe which factors could contribute to false or incorrect readings.
Step by step
Solved in 3 steps
- Do plants with watery sap have higher or lower water potential? Explain your answer using actual computed values.Describe 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.Calculate the ml/m^2 for a leaf with the surface area of .004m^2 and .30 ml water displaced
- When leaf water potential increases why does hydraulic conductivity increase as well in plants?The xylem cell has a water potential of -45 MPa and the mesophyll cell of the leaf has a water potential of -57MPa. Which way does the water move?What are the methods in measuring total leaf carbon content and lignin content from a leaf and please attach references from which study/article did you based your methods.
- (Use image provided to answer different parts) A) What do the results suggest about the part of the plant that regulates the thickness of developing leaves in response to light: a) developing leaves b) mature leaves c) whole plant B) Which treatment had leaves with the lowest surface area to volume ratios at a leaf size of 20mm: a) high apex treatmetn b) high whole treatment c) low apex treatment d) they all have same surface area to volume ratio C) Which leaf will lose water more readily under dry conditions? a) high apex b) high whole c) low apex d) they will all lose water at the same rate D) In what ways would the differences in leaf form evident between the High Whole and Low Whole treatments at the end of the experiment reflect adaptations to their different growth environments? Discuss specifically with respect to the effects of leaf form on photosynthetic rates and rates of water loss.List the types of solar collectors suitable to dry the fruits and fish? And Draw and explain its working operation?Scientists studied what caused leaf shedding in a drought deciduous (=shedding leaves during the dry season) subtropical species. They quantified the quantum yield (=efficiency) of the PSII complex and the leaf hydraulic conductance (=efficiency of leaf water movement) in leaves of that species during the wet to dry transition. Please describe the results in Figure Figure 1. Changes in leaf hydraulic conductance during the wet and dry season transition of a subtropical species
- 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 saturatedExplain the relationship between soil particle size and the field capacity of soil.By which thing the difference in concentration of ions between roots and soil is eliminated?
