- Water 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.Unless frozen, water is always in _______________, always ______________ within a plant from areas where it is abundant or under pressure to areas where it is rare or under tension.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 saturated
- Which plant water movement process is dependent on transpiration? root pressure capillary action cohesion-tension all of the aboveDescribe 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.Transpiration is when a plant release water vapor through its stomata which are pores its leaves and stems what other process in the water cycle is this most similar to explain your reasoning
- Draw a simple flow diagram or sketch to illustrate the flow path of water through a plant, from the point of uptake from the soil to transpiration and… (read in image below)the process that assists plants in gaining nutrients from soil is called Ion exchange Cation exchange Anion exchange Hydrogen ion exchangePhytoremediation is the utilization of plants in the clean up of a polluted area. In a maximum of four sentences, using a flow chart for illustration, outline the process of phytoremediation.
- Plants can transport water from their roots to their canopy regardless of their height. What properties of water make this long distance transport possible? Plants can transport water from their roots to their canopy regardless of their height. What properties of water make this long distance transport possible?

Poor drainage 2. Reduced compounds of manganese 3. Well drained and aeration soilWhich of the following would tend to DECREASE uptake of water by a plant root hair? Increasing the of the root hair Adding de-salinated water to the soil • Increasing concentrations of solutes in the root hair None of these would decrease uptake of water by a plant root hair
