lu6 desert biome Flashcards
leaves
fx
-Small leaves/ spines: conserve water in succulent plants
leafless plants conduct photosynthesis
where
in their green stems
leaves with hair
function, other plants leaaf, turn?
- help shade the plant: reducing water loss.
- other plants have leaves that turn throughout the day: expose a minimum surface area to the heat.
Waxy coating on leaves and stems
reduce water loss
Spines
discourage animals from eating plants for water
Roots near soil surface
soaked up water before evaporates.
Long root systems
spread out wide/go deep into the ground: absorb water
Flowers only open at
night: lure pollinators (more likely to be active during cooler night)
Some plants have a ———-(1) life cycle, ———(2) in response to
4, within, can evade ——-
- rain, growing, flowering, dying within one year.
- can evade drought.
slower growing plants,
thus requires less energy
dessert condition
7
1) very dry, often hot
2) annual rainfall average = ≤ 10 inches per year
3) when rain, comes often all at same time = rest of the year very dry
4) soil = sandy/rocky, unable hold much water
5) wind = strong, dry out plants
6) sunlight = direct shining on the plants, plants exposed to extreme temperatures + drought conditions.
7) must cope with extensivewater loss
