Question
Chapter 39.4, Problem 1CS
Summary Introduction
To draw: A model showing the way in which gravity might impact plant size by influencing transport.
Introduction: The plant's growth with respect to the effect of gravity is called gravitropism. This mechanism is controlled by plants growth hormones that are known as phytohormones. The auxin helps in the plant elongation ad plays an important role in deciding the plant height concerning the unnatural changes in gravity.

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
What does hydraulic conductance mean in the following?
The hydraulic limitation hypothesis proposes that reduced growth in taller trees is caused by decreased photosynthesis resulting from a decrease in hydraulic conductance promoted by a longer root-to-leaf flow path.

- Some seeds (tomato, for example) had been germinated and the seedling grew for 2 weeks in soil, where the soil water potential was maintained at -0.2 bars. The plants were then divided into 5 groups and each group subjected to a different soil water potential as follows: Group 1: 0 bars Group 2: -0.03 bars Group 3: -0.2 bars Group 4: -3.0 bars Group 5: -5.0 bars At the end of three weeks at these various soil water potentials, the plants that would have made the least growth would be expected in which group?
