Flashcards in Sun vs Shade Deck (17):
1
plants show ash optimal -- response curve both light capture and CO2 fixation are narrowly adapted to a given -- range
temperature
2
leaves may have specialized anatomy to deal with excess light: --, salt glands, specialized waxes increase reflection
hairs
3
excess heat is given off by emission of -- wave radiation, sensible heat loss, evaporative cooling
long-wave radiation
4
leafs conduct solar tracking such that -- is always perpendicular to the sun
lamina
5
a -- between lamina and petiole contains motor cells which generate mechanical forces by changing turgor
pulvinus
6
leaves are angled -- the sun in the cooler hours
toward
7
photo inhibition: reaction center of -- is inactivated or damaged
PS II
8
-- photoinhibition is reversible
dynamic
9
large amounts of excess light energy cannot be used in photosynthesis; non-reversible
chronic photoinhibition
10
most effective heat dissipator
zeaxanthin
11
plants grown in shade, leaves are thinner with more -- to capture diffuse light
spongy mesophyll
12
shade leaves are -- over large area for light capture
spread
13
shade plants utilize --
sunflecks
14
shade plants have -- leaf vein length per leaf area (vein density) representing lower capacity to transport water to stomata or sugars in the phloem
lower
15
meta-anaylses show shifts in A-ci curve parameters globally: Vcmax and Jmax increase with temp explained by -- to climate
adaptation
16
ecosystem-scale experiments (Free Air Carbon Enrichment) show the effects of carbon fertilization are partially mitigated by plant --
acclimation
