write the schematic outline of haplo_diplontic life cycle
Answers
Answer:haplo diplontic life cycle pattern of a plant
Explanation:pteridophyte and bryophyte both reveal a haplo diplontic life cycle . the diploid phase is not independent in bryophhytes : however , it is independent in the case of pteridophytes
Explanation:
a haplodiplontic life cycle pattern, such as in bryophyta or pteridophyta both the phases of life are multicellular. However, in bryophytes, the gametophytes are small, photosynthetic, independent and represent dominant phase. The partly or totally dependent sporophyte is physically attached to the gametophyte. The (n) spores dispersed by sporophyte germinate into individual gametophytic plants. However, in pteridophytes the 2n (diploid) phase is dominant, well organized, independent while the n phase though also free-living and independent is short lived and photosynthetic. In both of these groups of plants the mobile male gametes, antherozoid produced by sex organ antheridium, travel to archegonium (bearing an egg cell) via the medium of water. Egg cell is non-motile hence the reproduction is oogamous.
