        active during the day.
        
        Nocturnal
        active at night.
        
        Photonastic
        the opening and closing always happen in the same manner.
        
        Sleep Movements
        where the blade is elevated during the day and lowered during the night.
        
        Morphogenic Responses
        change in the "quality" of the plant that is a fundamental change occurs in the metabolism or the whole plant.
        
        Taxis
        is a response in which a cell swims toward (positive taxis) or away from (negative taxis).
        
        Critical Night Length
        short and long night plants need a different critical length of night.
  - - - Differential Growth
        one side of the tendrill must grow more than the other.
- - - - Presentation Time
        is the level length of time the stimulus must be present for the perceptive cells to react and complete transduction.
        
        Threshold
        refers to the level of stimulus that must be present during the presentation time to cause perception and transduction.
        
        all-or-none response
        after the threshold and presentation time requirements are met, the stimulus is no longer important;the response is now completely internal.
        
        Dosage-Dependent Responses
        the amount or duration of the stimulus affects the amount or duration of the response.
        
        Positive Feedback System
        concentration continuously increase at a rapid rate.
        
        Climacteric
        the rapid completion of fruit.
  - - - Cytokinins
        the addition to a tissue culture medium containing auxin and sugar stimulates cell division---- cytokinesis.
        
        Apical Dominance
        Dormancy in these axillary buds, the result being that each shoot tip has only one apical meristem.
      - Gibberellins
        125 are known, they are numbered obtained easily from fungi.
        
        Abscisic Acid
        originating from from fruits, leaves, and flowers. Containing only a single compound.
        
        Ethylene
        the only gaseous plant hormone, and it has the simplest structure.
        
        Brassinosteroids
        complex chemicals involved in leaf morphogenesis, root and stem growth and vascular differentiation.
        
        Jasmonic Acid
        involved in defense against animals and fungi.
        
        Salicylic Acid
        related to aspirin, involved in resistance to pathogens especially viruses.

        inhibiting the production causing negative outcomes.
        
        Entrain
        reset the rhythm.
        
        Circadian Rhythm
        a duration of time that is approximately 24 hours long.
        
        ABC model
        controls the basic aspects of organization.
