- Discuss Concepts Baobab trees (Adansonia spp.) store water in their trunks (stems) and, although the trees have leaves, considerable photosynthesis also occurs in the trunks. Cacti too have water-storing, photosynthetic stems. In terms of evolutionary adaptation, what does this information suggest about cacti and baobabs?arrow_forward1a.Discovery of genes controlling Gibberellic Acid (GA) synthesis and perception became very important during the Green Revolution, and remain important today. Why? Select one: a. Mutants with reduced GA levels are dwarfs. Many dwarf plants were important for the Green Revolution because the shorter plants can invest more energy into economically important parts like seeds (instead of stem length). b. Mutants with reduced GA levels are more resistant to herbivore damage (like caterpillars), increasing plant yields. c. Mutants with reduced GA levels allowed farmers to control fruit ripening more accurately. d. Mutants with reduced GA levels have increased photosynthesis 1b. What features are important for overall plant form? Select one: a. Iterative development and capillary action b. Iterative development and apical dominance c.
