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

17

fores lighting experiments show that shifting -- and light will also influence growth

cloud cover
