Questions and Answers
  • 1. 
    What is transpiration?
    • A. 

      The loss of water from a plant through its stomata

    • B. 

      The movement of sugars through a plant from a source to sink

    • C. 

      A part of a plant to which sugar is needed for metabolism

    • D. 

      When water evaporates from a plant

  • 2. 
    What is the tension-cohesion theory?
    • A. 

      Mass will remain tense uhless acted upon by cohesion

    • B. 

      Theory that water moves up a plant because of its cohesive properties and because of tension created by the loss of water from the leaves through transpiration

    • C. 

      The speed of light undergoes tension when passing the sun, and cohesion when in the shadow of a planet

    • D. 

      Water moves up a plant because of its tension properties and because of cohesion created by the loss of water from through its stomata
