Chapter 34- Plants Form and Function

Question 1

Leaves

Answer 1

Primary site of photosynthesis

Question 2

Answer 2

Gymnosperms

Question 3

Monocot Leaves

Answer 3

Angiosperms, have flowers, parallel leaves

Question 4

Eudicot Leaves (Dicots)

Answer 4

Branched leaves (one main branch and branches)

Question 5

Leaflet

Answer 5

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

Question 6

Stems

Answer 6

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

Question 7

Different kinds of stems

Answer 7

potato, daffodil, asparagus, cactus

Question 8

Answer 8

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

Question 9

Environmental Stressors

Answer 9

Wind, Aridity, Temperature, and Heterogeneity of resources

Question 10

Leaves in Humid

Answer 10

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

Question 11

Leaves in Dry

Answer 11

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

Question 12

Drought deciduousness

Answer 12

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

Question 13

Trichomes

Answer 13

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

Question 14

Waxy Cuticle

Answer 14

wax covering found in dry areas, reduces water loss

Question 15

Salt excretion

Answer 15

some plants can take up and excrete salt (albedo)

Question 16

Boundary Layer

Answer 16

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

Question 17

Increasing boundary layer

Answer 17

Large thin leaves, simple leaves, trichomes

Question 18

reducing leaf boundary layer

Answer 18

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