What is the primary transport system in plants responsible for the movement of water and nutrients?
The xylem
True or False: The phloem is responsible for the transport of water and nutrients in plants.
False
Fill in the blank: The movement of water through the xylem is driven by ________.
Transpiration
What is the role of the phloem in plants?
Transporting sugars and other organic compounds
What are the two main types of cells found in the xylem?
Tracheids and vessel elements
What is the process by which water is lost from the surface of plant leaves in the form of water vapor?
Transpiration
True or False: Evaporation and transpiration are two separate processes in plants.
True
Fill in the blank: Transpiration helps plants to regulate ________ and cool themselves.
temperature
What is the name of the specialized cells in plant leaves that control the opening and closing of stomata?
Guard cells
Which environmental factor can increase the rate of evaporation and transpiration in plants?
High temperature
What is transpiration?
Transpiration is the process through which water is lost from a plant through the stomata in the leaves.
can transpiration help in the uptake of water and nutrients from the soil by plants.
yes
What environmental factors can affect the rate of transpiration in plants?
temperature, humidity, wind, and light intensity
How does temperature affect transpiration in plants?
Higher temperatures generally increase the rate of transpiration in plants as it causes water to evaporate more quickly.
what can reduce transpiration in plants by closing the stomata.
Humidity
