1000 seeds were placed in damp soil, in the dark, at 25 °C for 4 days. Each day equal numbers of germinating seeds were removed, dried, and their components separated and weighed. The table shows the results. day 0 1 2 3 4 mean mass of whole seeds /mg 205 193 185 170 158 mean mass of seed cotyledons /mg 180 155 131 125 115 mean mass of radicle and plumule /mg 2 5 9 14 21 Which statements are supported by the data from this investigation? 1 Stored food in cotyledons provides materials for the growth of the radicle and plumule, during germination. 2 Whole seeds contain other structures beside the plumule, radicle and cotyledons. 3 Some stored food is respired to provide energy, and carbon dioxide is lost to the air.
