Nonvascular and seedless vascular plant tutorial Flashcards
six major apomorphies of land plants (lacking in charophytes)
- multicellular embryos
- sporopollenin
- apical meristem
- multicellular gametophyte
- alternation of generation
- cuticle
are the six apomorphies of land plants present in ALL extant land plants
NO- some characters are lost in lineages
four main traits of non-vascular plants
- dominant gametophyte
- flagellated sperm
- lack true roots, leaves
- lack of vascular tissue
3 main challenges faced by bryophytes
- water is still needed for reproduction
- cannot grow tall without vascular tissue
- still needs a spore dispersal mechanism
______: located at the top of the sporophyte, also known as the _____
- sporangium
- capsule
_____: haploid and produce by the sporophyte
spores
_____ develops into the gametophyte via _____
spores by meiosis
_____: stalk supporting the capsule and supplying nutrients
seta
_____: teeth-like structure that aids in spore _______
- peristomes
- dispersal
_____: a lid-like structure on the _____ that is lost when spores mature
- operculum
- sporangium
_____: situated above the operculum
calyptra
calyptra is situated above the _____
operculum
the calyptra is an enlarged ______ venter that protects the capsule
archegonial
_____: the male, sperm-producing reproductive organ
antheridia
antheridia is the ____ gametophyte
male
_____: female, egg-producing reproductive organ
archegonia
archegonia is the ___ gametophyte
female
six defining characteristics of extant SEEDLESS VASCULAR PLANTS
- vascular tissue
- true roots, leaves, stems
- dominant sporophyte
- independent sporophyte and gametophyte
- sporophylls
- flagellated sperm
homospory vs heterospory
homospory: sporangium on sporophyll -> one spore -> both antheridium and archegonia
heterospory:
microsporangia -> microspore ->microgametangia -> sperm
macrosporangia -> macrospores _>macrogametangia -> eggs
