Chapter 29 Flashcards
What do plants evolve from
Green algae
What are the closest living relative to plants
Charophyte algae
How do you scientist know that Charophyte algae is the closest living relative to plants
Morphological And bio chemical traits
Similarities in nuclear and chloroplast genes
What is sporopollenin
The protective layer charophytes Which allows them to tolerate occasional drying along the edges of ponds and lakes
What are some characteristics that distinguish charophytes from other plants
Plants have cuticles, stomata, multicellular dependent embryos, while the spores produced in sporangia, Population of generation, and ethical meristems
Describe the alteration of generations
1) Gametophyte enters my mitosis (hapliod n)
2) Gametophyte enter fertilization (haploid n)
3) The Gametophyte turn in to zygote (diploid 2n)
4) The zygote goes through mitosis
5) After my house as it turns into a sporophyte
6) The sporophyte goes through meiosis
7) turns into two n spores(haploid)
8) spores go through mitosis to turn back into a Gametophyte (haploid)
What are some of the several diverge plant groups that were named in the book
Bryophytes, Lycophytes, ferns, gymnosperms and angiosperms
What are nonvascular plants called
Bryophytes
What are some seedless vascular plants
Lycophytes and ferns
What are the two groups of seed plants
Gymnosperms and angiosperms
What Dominates the plant life cycles of masses and non vascular plants
Gametophytes
What are bryophytes and some examples
nonvascular plants that have a lineages Leading to the three extent clades
Ex) Liverworts, masses, and hornworts
What does the dominant generation of bryophytes consist of
Haploid gametophytes 
What is the role rhizoids
They anchor gametophytes to the substrate in which they grow
What produces the flagellated sperm
Antheridia
What do flagellated sperm require
A film of water to travel to the eggs in the archegonia
Describes what happens in the diploid state of the life cycle
The sporophytes grow out of archegonia and attach to the gametophytes
Depends on gametophytes for nourishment
What do smaller simpler sporophytes consist of
A foot, seta aka stalk and sporangium
Another word for peat moss and it environment
Sphagnum and it is common in large regions known as Peatlands has many practical uses including fuel
What were the first plants to grow tall
Ferns and other seedless vascular plants
What are some characteristics of vascular seedless plants
Well developed roots and leaves, dignified vascular tissue and sporophylls
Bryophytes do not form
A Clade
