Gravitrophism Roots Flashcards
1
Q
Roots are
A
positively gravitropic
2
Q
What happens if a root is exposed to an uneven gravitational pull
A
IAA is transported to the underside (closer to the pull of gravity).
3
Q
What does a higher concentration of IAA in the underside
A
inhibits cell elongation on the lower side.
4
Q
What does cell elongation cause
A
The root bends towards the gravitational pull.
