Question

experiments on the positive phototropic response of plants indicate that

Answer 1

it indicates that photosynthesis taking place in that plant or simply plant is alive

Answer 2

Complete Question:

Experiments on the positive phototropic response of plants indicate that

A) light destroys auxin.

B) auxin moves down the plant apoplastically.

C) auxin is synthesized in the area where the stem bends.

D) auxin can move to the shady side of the stem.

Answer:

Option d) is the correct answer.

According to experiments on plants' positive phototropic responses, auxin can travel to the stem's shaded side.

Positive phototropism:

• Positive phototropism is the process through which a plant moves toward a source of light.
• Positive phototropism is present in the shoot system, which includes the leaves, flower stems, lateral buds, and other elements that reach above the ground.

A phototropic reaction:

• In order to adapt to the changing environmental conditions in which they grow, plants have developed a wide range of reactions.
• The phototropic response is one such reaction, which involves the bending of a plant organ toward (leaves and stems) or away from (roots) a source of directional blue light.

The capacity of a plant to re-direct the growth of its shoots in the direction of a light source is known as phototropism. Plants need phototropism because it helps them maximise their capability for photosynthetic energy production.
