Which of the following describes a plant's response to a light stimulus?
Its leaves will wilt and fall off.
It will release its seeds and they will fall to the ground.
Its fruit will be damaged.
It will bend towards where it is.
What is a similarity between a plant's response to light and to heat?
Both affect the growth of the plant.

Plant 2: The leaves of the plant wilt and have dropped.
Which statement is true about the plants?
Both are responding to gravity.
Both are responding to heat.

A student completed an experiment investigating the response of tomato plants to gravity and created the table below.
What can you conclude from the observations? Look at the plant on its side.
Gravity does not affect the growth of a plant at all. The plant will not grow.
Gravity has no effect on the plant grown on its side and will just lay flat on the ground.
The stem of a plant will grow downward with gravity.
The stem of a plant will grow upward against gravity.
