14 cards from this deck
Movement of food substances in phloem up or down the plant
Loss of water vapour from leaves and stems of plant
Consequence of gaseous exchange via open stomata
Continuous flow of water up through plant via xylem
Increases rate (faster evaporation & more open stomata)
Decreases rate (reduced concentration gradient)
Increases rate (steeper concentration gradient)
Increases rate (more stomata open for photosynthesis)
Device measuring water uptake (via bubble movement) to indicate transpiration rate
Close and open stomata
Kidney-shaped
Thin outer walls and thick inner walls
Bottom/lower surface of the leaf
Allows gas exchange whilst minimising water loss (shaded & cooler)
