How does water enter the roots from the soil?
Transpiration travels from...
roots to leaves to stem
roots to stem to leaves
leaves to stem to roots
stem to roots to leaves
What term responds to touch?
Thigmotropism
Gibberellins
Geotropism
Where is xylem found in the plant?
leave -> roots -> stem
roots -> stem -> leaves
root hairs -> leaves -> veins
stem -> roots
What do the guard cells do?
Control active transport
Control nutrients moving into the cell
Controls the rate of transpiration (loss of water through the leaf)
What does phloem transport?
Water
Minerals
Fruit
Sugar
What is the main factor that influences the rate of sugar transport?
movement of water
Rate of photosynthesis
capillary action
uprooting plants
Where does sugar transport begin?
Roots
Leaves
Root hairs
Vascular bundles
How will lowered humidity (water in the air) affect the rate of transpiration (water transported in the plant)?
The vascular system includes BOTH the
pollen and anther
roots and leaves
xylem and phloem
palisade and spongy mesophyll
The rate of translocation in the phloem was observed to decrease steadily after a plant was placed in an environment without oxygen for several minutes. Why did this happen?
The cells in the plants stop respiring.
The xylem no longer takes in water for the plant.
Active transport of mineral salts can no longer occur.
The plant can no longer synthesize sugars to provide energy.
Higher temperature allows carbon dioxide to diffuse into the leaves faster.
Higher temperature allows water to be transported to the leaves faster.
Higher temperature allows the stomata to open wider.
Higher temperature allows the enzymes to function better.
