[Terjawab] An experiment was carried out to investigate the effect of gibberellic acid (GA) on the growth of dwarf pea plants. GA can be absorbed by leaves. Six identical pea plants were planted in pots containing 100 g of soil. The leaves of each plant were sprayed with equal volumes of water containing different masses of GA. The soil in each pot received 20 cm³ water each day and the plants were continuously exposed to equal light intensity from above. After seven days the stem height of each plant was measured and the percentage increase in stem heights calculated. The results of the experiment are shown in the table below. | Mass of GA applied (micrograms) | Percentage increase in stem height (%) | |---|---| | 0.01 | 90 | | 0.03 | 120 | | 0.05 | 160 | | 0.08 | 240 | | 0.10 | 320 | | 0.11 | 350 | 2.4.1 State a hypothesis for this investigation. 2.4.2 Identify TWO variables, not already mentioned, that should have been controlled to ensure the experimental procedure was valid. 2.4.3 How will an increase in the number of plants used in this investigation influence the results? 2.4.4 Explain the use of gibberellins in agriculture to improve fruit development.
