WebLife Cycle. As with all plants, lycophytes have two alternating generations. The dominant generation in lycophytes is the sporophyte generation which produces spores for … WebPteridophyta reproduces through spores since they are flowerless and seedless. In the beginning, spores are sent into the air. Spores grow into heart-shaped haploid gametophytes where both male and female sex organs are present. Sex organs get active as soon as the young gametophyte matures.
Pteridophyta: Characteristics, Classifications, Life Cycle
WebFigure 1 As do all plants, bryophytes alternate a gametophytic generation with a sporophytic one (a sporic meiosis, a life cycle in which meiosis gives rise to spores, not gametes). Each of the haploid (1 n) spores is capable of developing into a multicellular, haploid individual, the gametophyte. Webhaploid. Plants, and some algae, have a different type of sexual life cycle which includes not only a multicellular diploid stage but also a multicellular ______ stage as well. sporophyte; spores. The diploid stage of plant life cycle is called the_______. It produces haploid cells called _______ by meiosis. ten minute timer for kids with music
