Seven to ten days later, make the following measurements on each hypocotyl. Determine the average for each treatment. Graph the averages vs. IAA concentrations. How will you use thin layer chromatography to distinguish between the products, reactants and hourly extracts from the refluxing mixture. In the development of plant embryos, cells migrate from the suspensor to an area near the shoot apical meristem.
Plants have only one class of hormones, called gibberellins.
Give reasons to your answer. Many plants exhibit apical dominance, a phenomenon in which the shoot apex actively suppresses the formation of lateral branches. State the inhibitor functions of plant hormones. As the refluxing is done for six hours, advise the students to be early and also try to start the experiment at least one hour before the school day. No sandals or open toe shoes are to be worn in the lab.
