Which of the following best describes the positive plant response to light observed in the photograph? (hint: plant hormones cause this)

• The presence of light shrinks cells on the side of the plant facing the light, causing the plants to bend.

• The presence of shade releases auxins that elongate cells on the dark side of the stem, causing the plants to bend toward the light.

• The heat from the light evaporates water at a higher rate on the lit side of the plant, causing the plants to bend toward the light

• the presence of light loving bacteria in the soil on the lit side of the plant grow at faster rates, causing the plants to bend away from the light.
