Positively phototropic
2
Q
What happens when a shoot is
exposed to an uneven light
source
A
IAA is transported to the more
shaded part of the shoot
3
Q
What does a higher concentration of IAA in the shaded parts of the cell cause
A
A higher concentration of IAA in
the shaded parts cause cells in
the shaded area to elongate.
4
Q
What does cell elongation cause
A
The shoot to bend towards the
light
5
Q
Phototropism in shoots
A
Shoots are positively phototropic.
If a shoot is exposed to an uneven light source, IAA is transported to the more shaded part.
A higher concentration of IAA in the shaded parts cause cells in the shaded area to elongate.
Cell elongation causes the shoot to bend towards the light.
