Biology Ch 29

Plant Diversity I: How Plants Colonized Land

Sporopollenin A layer of a durable polymer in charophyte algae that prevents exposed zygotes from drying out. Forms the walls of plant spores, preventing them from drying out
derived traits of plantae (5) 1. alternation of generations 2. multicellular, dependent embryo 3. walled spores produced in sporangia 4. multicellular gametangia 5. apical meristems
alternation of generations the life cycle in which there is both a multicellular diploid form and a multicellular haploid form.
gametophyte the multicellular haploid form of organisms that have alternation of generations that produces haploid gametes by mitosis. Gametes unite and develop into sporophytes
sporophyte the multicellular diploid form of organisms that have alternation of generations that results from the union of gametes. Meiosis in the sporophyte produces haploid spores that develop into gametophytes.
Spore Reproductive cells that can develop into a new haploid organism without fusing with another cell
embryophytes a name for plants that refers to their shared derived trait of multi cellular, dependent embryo.
Sporangia multicellular organs of sporophytes that produce spores
sporocyte diploid cells within sporangia that undergo meiosis to generate spores; (aka spore mother cell)
gametangia multicellular plant structure in which gametes are formed.
archegonia female gametangia; a pearl shaped organ that produces a single nonmotile egg that is retained in the bulbous part of the organ
antheridia male gametangia; a moist chamber in which sperm is produced and released into the environment.
