copy deck
flowering plans; most widely distributed
angiosperms
Ginkgos and conifers; cone bearing; needles for leaves
Gymnosperms
transports water and minerals from roots to stems and leaves
xylem
transports food from leaves to rest of plant (mainly down)
phloem
fern leaves
frond
black dot on underside of fronds that is loaded w/ spores
sorus
non-vascular plant phylum
bryophyta
vascular plant phylum
tracheophyta
growing points of plants
meristem
growth tissue found b/w xylem and phloem (adds thickness)(annual rings)
cambium
male rep. part of flower
stamen
produces pollen
anther
femal rep. part of flower
pistal
sticky top of pistal
stigma
green petals that include and protect flower petals
sepal
transfer of pollen from stamen to pistal
pollination
when a seed starts to grow
germination
ripened ovary that protects and nourishes seed
fruit
short root that emerges from seed-turns into primary root
radicle
loose cells on outside of root that prtects and covers meristem tissue as the roon grows down
root cap
roots that grow from stems and leaves
adventitious root
step area above cotelydons
epicotyl
seed leaves
cotyledon
removal of bark around tree; kills it
girdling
light part of wood where water no longer is conducted
sapwood
dark region of xylem where water is no longer conducted
heartwood
tiny openings in lower epidermis that allows water vapor and O2 in
stomata
cells surrounding stomata whose movements control the opening and closing of stomata
guard cell
trees that lose all of their leaves at the end of a growing season in temperate regions
deciduous tree
normal separation of a leaf from a plant
abscission
the process in which water evaporates from the leaves of plants
transpiration
plant movements stimulated by external factors
tropism
Why are seedless vascular plants of millions of years ago important to us?
buried forests become deposits of coal, oil, and natural gas
Why do plants in the phylum bryohyta have to live in moist areas
because they lack tissues that store and transport water
List reasons why angiospers are so widely distributed
A)Relationship w/ insects
B)Efficient vascular systems
C)large leaves to make large amounts of glucose
D)Seeds are proteted in a closed struture
What is meant by dispersal of seeds and list things that help plants do this.
-dispersing seed away from parent plant
1)wind
2)water
3)insects
4)animals-birds
5)mechanical
List the three things needed for germination
A)moisture
B)Oxygen
C)Temperature
List functions of roots
1)anchor plant
2)absorb water
3)take in minerals
4)store food
How do leaves change color
They lose their chlorophyll and underlying colors start to come out
Write the equation for photosynthesis
CO2+H20+Sunlight->C6H12O6+O2+H20
Explain what is happening in the light reaction and dark reaction of photosynthesis
Light-water split by sun energy and hydrogen is trapped
Dark-CO2 is trapped and is split
