|
Functions of Auxin
|
1) promote stem elongation
2) promote root growth 3) promote fruit development 4) promote apical dominance |
|
|
Functions of cytokinins
|
1) promote root growth
2) promote seed and bud germination 3) promote cell division and differentiation 4) delay senescence |

|
|
definition: senescence
|
aging
|
|
|
definition: abscission
|
leaf drop in deciduous trees
|
|
|
place auxin is produced
|
apical meristems of shoots (shoot tip)
|
|
|
way auxin causes cell elongation
|
auxins stimulate proton pumps to increase acidity, breaking down cell walls, allowing for expansion
|
|
|
one reason plants bend towards the sun
|
sun causes auxin to diffuse away from the sunny side, causing the side farther from the sun to increase more
|
|
|
definition: apical dominance
|
terminal bud growth exceeds growth of lateral buds (plant grows taller than full)
