plant physiology Flashcards
bryophytes
lack vascular tissue
no roots or xylem
reproduce by spores
tiny
ex:mosses
tracheophytes
xylem and phloem
root and leaves
spores and seeds
gymnosperms and angiosperms
gymnosperms
conifers
angiosperms
flowering plants
roots
1-absorb nutrients
2-anchor the plant
3-stores the food
epidermis
absorption
cortex
storage of starch and organic substances
vascular cylinder
xylem and phloem
endoderma
select what minerals enter the vascular cylinder
asexual reproduction in plants
vegetative part produce a clone
sexual reproduction in plants
sperm joins egg and form sed
sepals
enclose the plant before opening
petals
colored leaves attract pollinator
pistil
female part
stamen
male part
dermal tissue
protective layer made of epidermal cells
cuticle
waxy Layer protects layers surface
trichomes
projection for protection
vascular tissue
xylem and phloem
xylem
water and minerals
phloem
food
auxins
stem elongation
softens the cell wall
phototropisms
unequal distribution of auxins
abscisic acid
promotes growth and seed dormancy
closes stomata during water stress
