2
New cards

Gravitropism

the growth of a plant in response to gravity

3
New cards

auxins

hormone-like chemical that speeds up or slows down plant growth.

4
New cards

where are auxins produced?

in the tips of shoots 

5
New cards

how and where do auxins move

Growth factors called auxins are produced in the tips of shoots and diffuse to the shady part of the shoot to stimulate the cell just behind the tips to elongate.

6
New cards

IAA

Indoleacetic acid

7
New cards

where is IAA produced?

shoots and roots

8
New cards

How does IAA move?

diffusion and active transport.

9
New cards

Where does IAA move in the shoot and the roots and what is the effect?

shoots: moves to the shaded parts, elongating the shoot and bending it towards the light.

roots: moves to the shaded parts, inhibiting the growth of the root, making it bend away from the light.
