Plant Bio Lecture 8

phylogeny of plants

what is this used to show

vascular tissue

xylem- water and minerals

phloem- sap and sugar

which parts are the xylem and phloem / what kind of tissue is it

what are the four main plant groups

non-vascular (bryophytes), seedless vascular plants, seed plants, vascular plants

bryophyte examples

liverworts, hornworts, mosses

seed plant examples

gymnosperms (conifers) and angiosperms (flowering plants)

vascular tissue

plant tissues that consist of cells that transport water and nutrients thruout the plant body. the two major types are xylem and phloem

xylem

vascular tissue that carries water and minerals from the roots to the rest of the plant

phloem

vascular tissue that carries sugar and organic nutrients throughout the plant

gametangium

the gametophyte stage of mosses consisting of a male antheridium and a female archegonium

gametophyte

multicellular, haploid stage of the life cycle that produces haploid gametes that fuse to form the diploid sporophyte

sporophyte

multicellular, diploid stage of the life cycle that through meiosis produces haploid gametes that become the gametophyte

spores and seeds

what are these examples of

what are the simplest group of organisms

bryophytes

what do bryophytes all reproduce with

spores

bryophytes

what are these examples of

tortula - a dry land moss

example of what - what kind of species

campylopus - moss

example of what

liverwort

what is it

hornwort

what is it

moss

what is it

polytrichum - gametophyte generation

what kind of moss - what is the green part

moss life cycle (polytrichum)

what kind of life cycle

marchantia- a liverwort

what is this - what species

liverwort (marchantia)

life cycle of what

left- antheridium (male)

right- archegonium (female)

liverwort

left and right

gemma cups of liverwort

what is this

what do gemma cups do

they will grow and break off from body

mode of asexual reproduction for liverworts

spanish moss - angiosperm

what is this- what species

reindeer moss- fungi

what is this- what species

club moss- vascular plant

what is this

sphagnum - peat moss - mulching agent, helps hold water in the soil

what is this - what species - what kind of agent

sphagnum peat moss (peat bogs)

what are these

bog people

what are these

peat as fuel

showing what

granite moss

what kind of moss

dawsonia - has hydroids and leptoids (conductive tissue)

what is this - what is special about its tissue

moss protonema

what is this

anthoceros - hornwort

what is this - what species

hornwort stomata - guard cells open and close stomata

what is this showing - what kind of cells and what do they do

what does stomata do

windows of leaves so CO2 can go in and oxygen and water can go out
