1

Leaves

Primary site of photosynthesis

2

Conifer Leaves

Gymnosperms

3

Monocot Leaves

Angiosperms, have flowers, parallel leaves

4

Eudicot Leaves (Dicots)

Branched leaves (one main branch and branches)

5

Leaflet

small leaves on one main branch, Main branch with leaflets is whole leaf

6

Stems

structural support, position leaves so exposed to sunlight, conduct food, water, and nutrients

7

Different kinds of stems

potato, daffodil, asparagus, cactus

8

Roots

absorb water and minerals from the soil, anchor the plant in place

9

Environmental Stressors

Wind, Aridity, Temperature, and Heterogeneity of resources

10

Leaves in Humid

Large, dark areas, maximize light capture, do not worry about water loss

11

Leaves in Dry

smaller, thicker to minimize water loss, do not worry about photosynthesis

12

Drought deciduousness

Leaves might be dropped (lose all surface area) in places with intermittent drought

13

Trichomes

hairs on surface of leaf, can change color of leaf,add layer

14

Waxy Cuticle

wax covering found in dry areas, reduces water loss

15

Salt excretion

some plants can take up and excrete salt (albedo)

16

Boundary Layer

heat up, can cause overheating and increase transpiration, needles and feathers

17

Increasing boundary layer

Large thin leaves, simple leaves, trichomes

18

reducing leaf boundary layer

smaller thicker leaves, divided or compound leaves, No leaves (photosynthetic stems)
