Document Summary
4 true or false & fill in the blanks (questions 17-19) 1: which photo-protective mechanism dissipates excess light energy absorbed by photosynthetic pigments as heat, oxidative phosphorylation, photosynthesis, carotenoid irradiation, beta-oxidation, non-photochemical quenching, which of these answers summarizes the reaction catalysed by the carboxylase activity of. Rubisco: 2c + co2 , 5c + co2 , 6c + co2 , 5c + co2 , 2c + 2xco2 . 4c: in the shoot apical meristem (sam) which zone contains the majority of stem cells? a). Short answer questions: (total of 12 marks: how do vacuoles help minimize the energy and resources plants use to grow? (2 marks, the vacuole is largely water. To increase water pressure and drive cell expansion the cost is actively pumping ions in the vacuole, and water follows. To increase in size the cell must then synthesize new cell wall and membrane, but the cell only has to produce a small amount of additional cytoplasm.
