Online Tests Unit 6

 Unit 6: System Physiology – Plant
A. Photosynthesis: Light Harvesting complexes; mechanisms of electron transport; photoprotective mechanisms; CO2 fixation-C3, C4 and CAM pathways.
B. Respiration and photorespiration: Citric acid cycle; plant mitochondrial electron transport and ATP synthesis; alternate oxidase; photorespiratory pathway.
C. Nitrogen metabolism: Nitrate and ammonium assimilation; amino acid biosynthesis.
D. Plant hormones: Biosynthesis, storage, breakdown and transport; physiological effects and mechanisms of action.
E. Sensory photobiology: Structure, function and mechanisms of action of phytochromes, cryptochromes and phototropins; stomatal movement; photoperiodism and biological clocks.
F. Solute transport and photoassimilate translocation: Uptake transport and translocation of water, ions, solutes and macromolecules from soil, through cells, across membranes, through xylem and phloem; transpiration; mechanism of loading and unloading of photoassimilates.
G. Secondary Metabolites: Biosynthesis of terpenes, phenols and nitrogenous compounds and their roles.
H. Stress physiology: Responses of plants to biotic (pathogen and insets) and abiotic (water, temperature and salt) stresses; mechanism of resistance to biotic stress and tolerance to abiotic stress.
