Thus, during the life cycle of any sexually reproducing plant, there is an alternation of generations between gamete producing haploid gametophyte and spore producing diploid sporophyte. The sporophytes bear sporangia that are subtended by leaf-like appendages called sporophylls. Diversity in the living world. In sexual reproduction, the sex organs antheridia and archegonia are produced at the apex of the leafy shoots. is based on few morphological characters.

E.g.-, are extracted from the members of phaeophyceae such as Laminaria, Macrocystis and. gemma). These seeds are not covered. The sexual reproduction is of oogamous type, i.e., takes place by the fusion of distinct male and female gametes. The phaeophyceae are commonly called as brown algae. Unlike Cycas, here the micro and megasporophylls form compact male and female cone or strobilus respectively. The plant body of Wolffia consists of tiny flat oval green stem (phylloclade) having a few small roots. The leaves in pteridophyta are small (microphylls) as in Selaginella or large (macrophylls) as in ferns. Algae are useful to man in a variety of ways, like-. Following fertilization, zygote develops into an embryo and the ovules into seeds. Fig. Members of this class are commonly called. Sexual reproduction occurs through isogamy. Term gymnosperm was introduced by Theophrastus. Then these spores germinate to produce gametophyte. Download Revision Notes as PDF.

The outer part (pectin) dissolves in water to form a mucilaginous sheath. Meiosis in the zygote results in the formation of haploid spores. Examples of liverworts are - Riccia, Marchantia, Pellia, Porella, etc. The thallus is an unbranched and uniseriate filament where cells are arranged in a single row. Gymnosperms are seed bearing, non-flowering plants. Many algae such as Volvox, Spirogyra and some species of Chlamydomonas represent this pattern.
