sepal
|
encloses bud before blooming
|
|
|
meristem
|
growth tissue
|
|
|
photosynthesis equation
|
6CO2 +6 H2O + light = C6 H12 O6 +6O2
|
|
|
Rubisco
|
enzyme in calvin cycle. binds co2 to RuBP
|
|
|
Auxins
|
produced by apical meristem. stimulates cell elongation. causes phototropism, gravitropism, thigmotropism
|
|
|
cytokins
|
stimulate cell division, growth of lateral buds. causes dormant seeds to sprout
|
|
|
giberellins
|
produce increase in stem length and fruit size
|
|
|
ethylene

abcission
|
falling of leaves...etc
|
|
|
gravitropism
|
plants response to gravity
|
|
|
phototropism
|
tendency of plants to grow towards sunlight
|
|
|
phytochrome
|
changes timing for season activities
|
|
|
thigmotropism
|
plants response to touch
|
|
|
Light Dependent reaction
|
light into thylakoid membrane. makes hydrogen, oxygen, ATP, and NADPH
|
|
|
Calvin Cycle
|
6CO2 become 6 unstable intermediates of 36 carbons. 12 ATP and 12 NADPH from light dependent reaction are used to make the intermediates into 12 PGAL. 2 of the PGAL go on to become Glucose. the 10 others use 12 ADP and 12 NADP to become 6 RuBP which continue in the cycle
