Assignment Questions
Question 1
1.1.Two students have compared the genome wide analyses of expression profiles
in the leaves of maize and they found that the leaves of maize either do or do not
develop Kranz anatomy. Please explain.
1.2.Explain by means of various examples how chemical and atmospheric
pollution as well as UVB radiation affect plant anatomy.
Question 2
Plants were fumigated with hydrogen fluoride and the other set of plants were
fumigated with CO2. After few days, the other set of plants show shrinkage while
the other set of plants show significant increase in leaf thickness. Discuss the
results of this experiment.
Question 3
Experiment conducted by Buisson and Lee (1993) on the effects of simulated
canopy shade demonstrated that leaves of Carica papaya grown under reduced
irradiance were significantly thinner with lower specific weight. Critically
evaluate the experiment result of Buisson and Lee.
