Question
Chapter 38.2, Problem 2EQ
Summary Introduction
To identify: The potential sentinel plants that were starting to experience a deficiency of phosphorous.
Introduction: John Hammond and his colleagues identified the SQD1 gene which can be used to monitor phosphorous level in plants. SQD1 optimize plant phosphorus requirement by making the plant respond to low levels of phosphorous requirements.

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.
