Explanation: Both gymnosperms and angiosperms have vascular tissue that is specialized for transport of minerals, water, and organic compounds. Angiosperms represent approximately 80 percent of all the known green plants now living. The key difference between them is that, in thallophytes, the body is a thallus and not differentiated into stems, leaves, or roots whereas, in bryophytes, though the body is not well-differentiated, they may have stem-like and leaf-like structures. Along with bryophytes and pteridophytes varieties of higher plants like grasses, some seasonal herbs or shrubs grow on barren land during monsoon due to favourable conditions. a. megaphyll Megaphyll is The sporophytic leaf of the euphyll group, growing by means of either marginal or apical meristems, having multiple, branched veins, and having an associated leaf gap female.Syn: megasporophyll Megasporophyll leaf that produces megaspores b. lycophyll.
