You can check 31+ pages evolution of sporophyte in bryophytes ppt solution in PDF format. 16The variable distribution of orthologs across stomata-bearing land plants and the recent evolutionary origins of some Arabidopsis components by gene duplication eg SPCH MUTE ERECTA and YODA raise the possibility that uncharacterized genes in bryophytes and early-diverging tracheophytes may play important roles in the development and function of stomata and may have contributed to stomatal origins and early evolution. Reduction of water-dependent gametophyte. The sporophyte with large and prominent leaves is megaphyllous. Check also: analysis and evolution of sporophyte in bryophytes ppt Sporophytes of hornworts mosses haveSporophytes of hornworts mosses have stomata Bordered by guard cells which resemble stomata of vascular cells.
The sporophyte of bryophytes is called sporogonium which generally consists of a single terminal sporangium monosporangiate with a bulbous foot and with or without an unbranched stalk or seta. Vascular tissue improved waterfood transport.

Bryophytes Chapter 22 LEARNING OBJECTIVE 1 Discuss some environmental challenges of living on land Describe how several plant adaptations meet these challenges Colonization of Land Plants required evolution of structural physiological reproductive adaptations Plants produce gametes in multicellular gametangia that.
The branches are developed in whorls from the nodal region of the stem. Sporophyte diploid generation is attached to and dependent on the gametophyte for the entire life cycle. PowerPoint PPT presentation free to view. In young stages the sporophyte is completely surrounded by involucre. The roots are adventitious. 23The Life Cycle of Bryophytes bryophytes are diplohaplontic plants with a heteromorphic alternation of generations within the sporangium spores are formed by meiosis protonema and gametophores develop after germination antheridia and archegonia produce sperm and eggs after fertilization a new attached sporophyte is formed.
Evolution Of The Sporophyte In Brophytes The sporophytes with small and scale like leaves are called microphyllous.
