Cards

Term
What do land plants have in common with algae?
Definition
pigments
cell wall (cellulose)
Storage Compound - starch same
Term
How do land plants differ?
Definition
Waxy cuticle with stomata
reproductive organs house in jacket of sterile tissue
Water transporting tissue

All land plants sporic meiosis.
Term
Nonvascular Plants
Definition
No veins
No water transport
Term
Seedless vascular plants
Definition
Ferns, vascular tissue but no seeds
Swimming sperm cell!
NO POLLEN
Term
Seed Plants
Definition
Vascular
Pollen
Term
Division Bryophyta
Nontracheophyte Plants
Definition
MOSSES
Plant haploid
Produces egg and sperm in archegonia and antheridia
swimming sperm

Rhizoids grip surface (no roots)
Term
Archegonia
Definition
female eggs (female part)
Term
Antheridia
Definition
sperm cells (male part)
Term
Division Hepatophyta
Nonvascular Plant
Definition
LIVERWORTS
Life cycle: same as mosses
Lobed, flat thallus with rhizoids

Umbrella structure hold antheridia and archegonia
Also Gemmae cups (water hits cup, spreads spores)
Term
Division Anthocerophyta
Nonvascular Plants
Definition
HORNWARTS
lifecycle same as mosses
sporophyte is horn shaped grows out of thallus
Term
Seedless Tracheophytes Vascular
Division Rhyniphyta
Definition
The OG plant! helped make leaves and roots!
EXTINCT
Lignin
Lack roots and leaves, ALL STEM
Larger stage in life cycle was diploid bore sporangia
Gametophyte was branched

Made microphylls and megaphylls
Le
Term
Liginin
Definition
In cell wall of seedless tracheophytes, it's in any woody part of a tree bark!!!
Term
Microphylls
Definition
Only one vein, developed from sterile sporangia
Term
Megaphyls
Definition
complex leaves, small branches of stem becoming web together.
Term
Seedless Tracheophytes (Vascular)
Division Psilophyta (whiskferns)
Definition
MOM KILLER
Plant diploid in sporophyte
Produces spores by meiosis

Spores gorw into tiny free living gametophyte
Gametophyte produces eggs and swimming sperm!
Fertilized egg grows into sporophyte that obliterates MOM
Sporophyte has one mom, but sporophyte produce thousand of spores

No roots or leaves!
Vascular tisue for water + sugar transport
Term
Dichotomous Branching
Definition
Y branching pattern
Term
Gametophytes
Definition
haploid stage of plant (multi cellular)
Term
Division Lycophyta
Seedless Tracheophytes (Vascular Plants)
Definition
Life cycle similar to Psilophyta
Produces spores in cone like strobilus
One sporangium per sporophyll
Homosporous or heterosporoous

Has roots and leaves (microphylls!)
Extinct forms help produce coal deposits
Help produce coal!!!!
Term
Strobilus
Definition
PINECONES!! leafs coming up stem, sperangium on top of cone
Term
Sporophyll
Definition
Sporangium bearing leaf
Term
Sphenophyta (horsetails)
Seedless Tracheophytes vascular plants
Definition
Like psilophyta life cycle!
Have strobilus
Homosporous

underground stem gives rise to leaf bearing shoots
Extinct forms were trees gave rise to coal deopsits!
Term
Division Pterophyta FERN
Definition
Spores produced in sori on bottom of leaf!
Gametophyte is called prothallus - (super tiny pre plant)

Leaves megaphylls!
Circinate vernation
Extant tree forms and extinct
Help form coal!
Term
Circinate vernation
Definition
unroll at spring!
Unroll like a party blower!!!
Term
Extant
Definition
opposite of extinct!!!
Term
Division Coniferophyta
Gymnosperms
Definition
Gametophyte is greatly reduced
Megaspores grow into few celled female gametophyte on female cone.
microspores develop pollen grains on male cones
Fertilized zygote surrounded by food stores and a seed coat

Needle like or scale like leaves adapted to dry conditions
Trees

NO VESSELS
Term
Gymnosperms
Definition
Seeded but flowerless tracheophytes
NAKED SEEDS
Term
Tracheids
Definition
have gaps in secondary cell wall
have little holes to move water through safe for dry conditions
Term
Vessels
Definition
have gaps in their primpary and secondary wall
Have bigger holes! Move more water! lose water
Term
Division Cycadophyta (Cycads)
Gymnosperms (seeded but flowerless tracheophytes)
Definition
Fern like, but with cones!
Within the pollen grain the sperm swim!
Term
Division Ginkgophyta
Gymnosperms
Definition
Leaves are fan shaped
Petrified forests
Term
Division Gnetophyta
Gymnosperms
Definition
MORMON TEA - huge upper!
Have vessel elements
Bizarre polyphyletic group
Term
Anthophyta Flowering plants
Definition
Similar to conifers
Megasporangia and microsporangia are housed in flower
has pistil or carpel stigma style ovary
stamen
anther/filament

Ovary wall becomes the fruit!!!
Double fertilization!!!
USE animals to transfer pollen
Term
Pistil or Carpel
Definition
Swollen Ovary base sticky patch recives pollen
Term
Style
Definition
How flower is exposed, the reproductive organs
Term
Stamen
Definition
lifts anther!
Term
Anther
Definition
where pollen is made!
Term
Sepals
Definition
GREEN BUD THAT PROTECTS flower!!
Term
How do you know a flower is a flower?
Definition
Need an ovary or an anther to be a flower!!!
Term
Wind pollination vs. Animal pollination

Why do fruit taste good?
Definition
Animal pollination is 200x more effective!

To have animals eat them, help spread the seeds!!!
Term
Monocotyledonae
Division Anthophyta: flowering plant
Definition
One seed leaf (one leaf when initally germinated)
Grasses, lilles,
Parallel venation, parallel veins.
Arranged in 3's!!!
Term
Diccotyledonae
Division Anthophyta: flowering plant
Definition
Two seed leaves (2 leaves when initially growing)
Maples rose what not!
Most fruit are considered ROSES!
Netted venation, veins EVERYWHERE
Arranged in 4's or 5's!
Term
Herb in botany?
Definition
Any soft body plant
