Tropismo y hormonas

Plants respond to stimuli through growth, known as tropisms, which direct them towards or away from stimuli like light, gravity, and water. These responses are regulated by the hormone auxin, which promotes growth by accumulating in specific areas. Understanding auxin's effects allows for its use in agriculture to enhance root development and fruit production.

Which of the following is NOT a type of plant tropism?

• Geotropism

• Phototropism

• Thermotropism

• Hydrotropism

What role does auxin play in plant growth?

• It causes leaves to fall off

• It prevents plants from bending

• It inhibits root growth

• It promotes growth by accumulating in shaded areas

How does auxin distribution affect a plant's response to light?

• It causes the plant to grow away from the light

• It causes the plant to bend towards the light

• It makes the plant grow taller

• It has no effect on plant growth

In what way are auxins used in agriculture?

• To stimulate root development in cuttings

• To change the color of flowers

• To increase leaf size

• To slow down plant growth

Why are tropisms important for plant survival?

• They help plants avoid predators

• They allow plants to seek optimal conditions for growth

• They enable plants to produce more seeds

• They make plants more colorful
