Answer 3

I dont even understand the question honestly

Answer 4

Yes

Answer 5

So would that be my answer ?

Answer 6

Phototropisms
In a shoot, the shaded side contains more auxin. This means that the shaded side grows longer, causing the shoot to bend towards the light. The diagram shows the typical results seen when growing oat seedlings in a box, with a light at one side.
uxins have the opposite effect on root cells. In a root, the shaded side contains more auxin, but this time the shaded side grows less than the light side. This causes the root to bend away from the light.
Geotropisms
Auxins are also involved geotropisms. In a root placed horizontally, the bottom side contains more auxin than the top side. This makes the bottom side grow less than the top side, causing the root to bend in the direction of the force of gravity.
In a shoot placed horizontally, the bottom side contains more auxin than the top side. This makes the bottom side grow more than the top side, causing the shoot to bend and grow against the force of gravity.
