If a plant shoot is kept in a dark room and the hormone auxin is concentrated only on the left side of the shoot, what is the most likely growth response?

True or False: In a plant shoot exhibiting phototropism, cells on the side of the stem furthest from the light source elongate more than cells on the side facing the light.

The specialized cells in a root that contain dense starch grains used for sensing gravity are known as __________.

Because plants are stationary, they use controlled growth responses to adjust their position __________ to their environment.

In stems, __________ phototropism ensures that leaves are positioned to capture the maximum amount of sunlight for photosynthesis.

The shoot will bend toward the right because cells on the right side elongate more

The shoot will bend toward the right because cells on the left side elongate more

The shoot will bend toward the left because cells on the left side elongate more

The shoot will grow straight upward because auxin requires light to stimulate cell elongation
