Which first step in the orig in of the seed can already be observed in the pterophytes and lycophytes?
The first step in the origin of the seed that can be observed in pterophytes (ferns) and lycophytes is the development of the sporangium, where spores are produced. Both groups exhibit a dominant sporophyte generation that produces spores through meiosis, which is a precursor to seed formation. Additionally, the presence of a protective structure around the spores, although not a seed, hints at the evolutionary transition towards seed development seen in seed plants.
