If you read that a plant has a bulb or tuber, can you always be certain exactly what the botanical structure is?Which of the following statements characterize the megaphyll line of evolution? A) They differ from microphylls by developing a single, unbranched vein rather than a branched vascular system.B) They are believed to have evolved from branching telomeres that flattened and developed photosynthetic tissue between the branches.C) They developed into leaves that can also be called lycophyllsD) They developed into the large leaves of the angiosperms
