Answer the following statement true (T) or false (F)
A group of geneticists exposed the seeds of a dicot plant to various levels of radiation in order to induce random mutations. Many of the irradiated seeds failed to germinate
Some of the seeds, however, germinated in the lab and were carefully studied. The scientists discovered a mutation that prevents the formation of a hypocotyl hook during germination. Based on this scenario, the mutant plant most likely germinated A) but was unable to photosynthesize. B) but damage to the cotyledons prevented the seedlings' emergence from the soil. C) but the mutated hypocotyl hook caused damage to the emerging root tip. D) and grew like a normal plant. E) but the mutated hypocotyl hook failed to push the cotyledons above the soil.
