Geotropism (also called graviotropism) involves

• leaves

• roots

• roots and leaves

They charted the movement of these flowers towards the sun at 8 AM, noon and 6 PM. Now, their science teacher wants to know why they think the plants moved with the sun during the day.

• It is protecting itself from the sun.

• It is increasing water flow by moving.

• It is storing up heat so it can survive on cold nights.

• It is maximizing the energy they absorb to create more food. More sun equals more food.

Why do roots spread out to the sides in space, but grow downward on land?

• The momentum of space caused the roots to spread out.

• Roots grow towards the pull of gravity. There is no gravity in space, so they spread out.

• There is more light than on earth. The light made them spread apart.

• In soil on Earth, they are held in by soil so they can't grow out to the sides.
