• Roots grow downward and stems grow upward.

• Roots grow upward and stems grow downward.

• Both roots and stems grow sideways.

• Roots and stems do not respond to gravity.

What do plants do in response to light?

• Plants stop growing altogether.

• Plants change color to match the light.

• Plants produce more flowers than usual.

What is the effect of too much heat on plants?

• It can cause wilting or damage to the plant.
