What is DIRECT CONTACT LOCAL
Short day plants require a minimum number of hours of ______ before they will flower
What is DARKNESS
This hormone is involved in ensuring a plant can withstand drought conditions by causing stomata to close.
What is ABSCISIC ACID
Two factors affecting membrane fluidity.
What is TEMPERATURE AND COMPOSITION (CHOLESTEROL AND SATURATED/UNSATURATED FATTY ACIDS)
Three types of integral protein receptors for hydrophilic and/or large molecules.
What is G Protein Coupled, Receptor Tyrosine Kinase, and Ion Channel
Flowering in _________ plants is controlled by plant maturity.
What is DAY-NEUTRAL
This hormone is often released during stress and is involved in the triple response, apoptosis, fruit ripening, and leaf abscission.
What is ETHYLENE
These molecules move easily through a plasma membrane.
What are hydrophobic and small molecules.
What is SHAPE
Plant hormones are chemical ______ and are released in response to _________.
What is STIMULI
This hormone will be released from an embryo within a hydrated seed which subsequently leads to the breakdown of endosperm.
What is GIBBERELLINS
Type of transport whereby molecules, ions move across the plasma membrane, down their concentration gradient, with the help of a transport protein e.g. channel or carrier protein.
What is FACILITATED DIFFUSION
Transduction succeeds in _____ and _____ a signal.
This plant hormone moves to the shaded part of a plant and leads to positive phototropism.
What is AUXIN
This hormone get released upon injury of the plant and its release can lead to the production of volatile attractants.
What is JASMONATES
