After entering the root hairs, what part of the plant will water into next?
Xylem
The tension that pulls water from the stems into the leaves
Cohesion
The process in which water evaporates through stomata in the leaf. (loss of water of plants)
Transpiration
Does every epidermal cell have a root hair?
No
What are the two conducting cells in the xylem?
Tracheids and vessel elements
After exposing celery stalks to air, What do the results indicate about a continuous water column versus a water column with air interrupting the column?
Continuous water allows for more rapid movement
What type of tissue in the celery stalk was stained by the dye?
Xylem
Why was the xylem the tissue that was dyed in the celery stalk experiment?
Water moves through the xylem
When the stem of carnation is submerged in dye, which part of the flower is the dye located in?
Veins in pedals
What can be concluded about the movement of water in the plant?
Transpiration occurs in the flowers and leaves
How do the turgid guard cells of Crassula form a stomatal pore?
Bow and form opening to create the pore
Did NaCl solution cause the stomata to close? Why or why not?
Yes, because the cell was put into a hypertonic solution, and it became flaccid
What is the advantage of closed stomata when water is in short supply?
The plant can preserve water
What is the disadvantage of a closed stomata when water is in short supply?
No gas exchange

How would you cure a plant suffering from these deficiency symptoms?
Provide them with the nutrients
Why are certain deficiencies either localized to or appear in certain areas of the plant? (2)
Each nutrient has a mobile ability
Iron is deficient in new leaves because its immobile
