Gravitrophism Shoots

Question 1

1) Shoots are

Answer 1

negatively gravitropic.

Question 2

2) What happens when a shoot is exposed to an uneven gravitational pull

Answer 2

IAA is transported to the underside (closer to the pull of gravity).

Question 3

3) A higher concentration of IAA in the underside causes…..

Answer 3

cells in the underside to elongate.

Question 4

Cell elongation causes

Answer 4

the shoot to bend away from the gravitational pull

Question 5

All of it

Answer 5

Shoots are negatively gravitropic.

If a shoot is exposed to an uneven gravitational pull, IAA is transported to the underside (closer to the pull of gravity).

A higher concentration of IAA in the underside cause cells in the underside to elongate.

Cell elongation causes the shoot to bend away from the gravitational pull.
