quarter 4 Flashcards
(26 cards)
This controls the opening and closing of pores
GUARD CELLS
Adjust the amount of output
EFFECTOR
It is a short term response in which the cells surrounding the site of infection are either killed or signal to undergo cell death
HYPERSENSITIVE RESPONSE
Elongated cells in the phloem that helps transport sugar
SIEVE TUBES
A structure that detects the change
RECEPTOR
Elongated cells in the xylem that helps transport water and nutrients
TRACHEIDS
A process where water exits the plant through the stomata of the leaves because of evaporation
TRANSPIRATION
Refers to the movement of liquid across a solid surface
CAPILLARY ACTION
Movement of plant in response to mechanical stimulation
THIGMOTROPISM
This provides a pathway for the direct exchange of gases between the internal tissue of plants and atmosphere
LENTICELS
The outcome of the adjustment
RESPONSE
Gas enters through this specialized pores
STOMATA
The tendency of water to pass through the semipermeable membrane
OSMOSIS
This is a specialized blood cell that travels through the circulatory system to destroy them
LYMPHOCYTES
A structure that determines the appropriate response
CONTROL CENTER
The ability of the body to maintain a constant interval environment, it helps the body to function optimally
HOMEOSTASIS
Movement of a plant in response to water
HYDROTROPISM
This allows the water to move up through a plant
ADHESION-COHESION
It transports sugars and other metabolic products from the leaves to the rest of the plant
PHLOEM
Different gases are transferred to opposite directions across a respiratory surface
GAS EXCHANGE
Movement of the plant in response to light
PHOTOTROPISM
It transports water and nutrients from the roots to the different parts of the plant
XYLEM
It allows the output to enhance and continue
POSITIVE FEEDBACK MECHANISM
It allows the body to go back to its normal or ideal state
NEGATIVE FEEDBACK MECHANISM
