Major Branches of Plant Evolution
What phylum are mosses?
bryophyta
what phylum are whisk ferns?
pterophyta
moss are
whisk ferns are
term for 3 phyla: bryophyta (moss), hepatophyta (liverworts), anthocerophyta (hornworts). gametophyte is the predominate stage of the life cycle
bryophytes
what is it? what phylum?
which of these are gametophytes
which of these are sporophytes
what do the pine cone and the flower have in common
The asexual and usually diploid phase, producing spores from which the gametophytes arise by meiosis
Dominant in vascular plants
since it is produced from a haploid egg cell fertilized by a haploid sperm cell, each sporophyte cell has a double set of chromosomes, one set from each parent
The gamete producing (by mitosis) and usually haploid phase, producing the zygote from which the sporophyte arises
Dominant in nonvascular plants
Within __ plants is the phloem (vessel that transports food) and the xylem (transports water). Higher plants. Tracheophytes.
__ plants are simple plants without a phloem or xylem. No true leaves, roots or stems.

whisk ferns
__ plants of __ are leafy and usually stand upright. radially symmetrical. leafy green portions are often only one cell thick (except at the midrib). have specialized cells that aid in the absorption and retention of water.
