What three important materials do roots collect from the surrounding environment? |
Water Mineral Nutrients Gas Exchange (O2) |
|
|
What important resource can the above-ground exchange system obtain from its surroundings that the below-ground exchange system cannot? |
CO2 Sunlight O2(?) |
|
|
Why does the leaf tend to lose more water from one surface than the other? |
Because stomata are on under surface. |
|
|
how useful are there? (1) O2, (2) CO2, (3) Mineral nutrients, (4) Water |
1) Waste collector for cellular respiration 2) For photosynthesis (resource of carbon) 3) For all important biological molecule 4) For photosynthesis, reaction medium |
|
|
Trees simply are constructed of two branching exchange system, which is _____ and _____. |
The roots The branches |
|
|
_____ system exploits the fluid motion of the atmosphere to consume necessary gases and to dispose of _____ gases and collect _____ (w/ ex of this system). |
Above-ground Branching waste resources (CO2) |
|
|
_____ System is solid, opaque and always dark. |
Below-ground Branching |
|
|
Biologists call useful salts in the soil as _____ |
nutrients |
|
|
Leaves exchange gasses with the atmosphere through _____. |
stomata |
|
|
Tiny pores on leaves' undersurface |
Stomata |
|
|
Internal exchange surfaces are kept _____. For this reason, leaves are the tree's main site of _____. |
moist with water water loss |
|
|
Several factors that can increase the amount of water lost by a leaf |
1) The larger the leaf, the more water it loses. 2) The warmer the leaf, the more water it loses. 3) The more that a leaf’s undersurface is directly exposed to moving air, the more water it loses. |
|
|
A favorable or advantageous circumstance or combination of circumstances is called _____. |
Opportunity |
|
|
An indication of imminent harm, danger, or pain is called _____. |
Threat |
|
|
Individual living things maintain the living state by _____ and _____. |
Exploiting opportunities (receiving rewards) Avoiding threats (reducing stress) |
|
|
Two conditions that met by adaptations |
1) It maintains or increases the fitness of an individual 2) It is the result of many generations of evolution by natural selection. |
|
|
A description of the weather patterns for a region throughout the year |
Climate |
|
|
Climate is often expressed in terms of _____, _____, and _____. |
Temperature Rainfall Day length. |
|
|
Five rewarding feature of plants' leaves in Chaparral ecosystem |
1) Low, ground covering growth pattern (shade the soil to get access to more water) 2) Small leaves (Avoid water loss from stomata) 3) Vertically oriented leaves (Absorb less light, but also keep sunlight) 4) Light colored leaves (Keep low temperature) 5) Spine-tipped leaves (葉のギザギザ)(Create heat sink, keep water as much as possible) |
|
|
Five rewarding feature of plants in Desert ecosystem |
1) Tall, vertical growth pattern (Absorb less heat) 2) Photosynthesis in stems (Alternative way of photosynthesis) 3) No leaves (Stop reducing water) 4) Water storage in modified stems (keep water since they don't know when it would rain next. Also waxy) 5) Clusters of dangerous spines on stems (Protection against predators who try to eat their nutritional stem) |
|
|
Five rewarding feature of plants in Tropical Rain Forest Ecosystem |
1) Large, shallow roots (Get nutrients on the surface of the soil [most nutritional part]) 2) Large leaves (Get sunlight under competition of getting area) 3) Tall, and very large growth (Get sunlight by getting taller than the others) 4) Umbrella-like canopy top (Occupation) 5) Epiphytic lifestyle (Different strategies by each plants) |
