-
cotyledon
seed leaves produced by embryo that serve to absorb nutrients packaged in the seed until the seedling is able to use it's first true leaves for photosynthesis
-
angiosperms
flowering plants
-
monocots
- have one cotyledon
- parallel veins
- scattered vascular bundles
- fibrous roots
- petals in multiples of 3
-
dicots
- 2 cotyledons
- net-like veins
- vascular bundles in a ring
- tap roots
- petals in multiples of 4 and 5
-
vascular bundle
a strand of primary conductive plant tissue consiting of the xylem and phloem
-
node
where the leave attaches to the shoot
-
internode
space betweem leaves
-
blade
main part of the leaf
-
petiole
attaches leaf to node in dicots
-
shoot system for a monocot
draw
-
shoot system for a dicot
draw
-
sheath
attaches leaf to node in monocots
-
terminal bud
highest point of the shoot
-
axillary bud
located at junction of leaf and shoot, dormant
-
root
supports and absorb water and minerals from soil
-
root hairs
extensions of individual cells that absorb
-
what can roots be modified to be?
-
ratio of roots to shoots
1:1
-
apical meristem
meristem at the tip of a root or shoot that causes the root or shoot to increase in length
-
apical dominance
a way for the plant to use its esources to get taller, the terminal bud produces a hormone to inhibit the growth of axillary buds
-
be able to draw plant cell
draw
-
primary cell wall is made of:
cellulose
-
turger pressure
created when the plasma membrane presses against the cell wall
-
secondary wall
- only in plants than need support
- beween plasma membrane and primary cell wall
- made of cellulose and lignin
- strong and hard
-
protoblast
- everything inside cell wall
- (plasma membrane, all cytoplasm and all its contents)
-
vacuole
stores pigments and waste products
-
plastids originated by
endosymbiosis
-
chloroplasts
photosynthesis occurs
-
amyloplast
storch storage
-
chromoplasts
contains pigments
