Question

Which statements describe hormones in plants? Check all that apply.

Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.

Answer 1

Answer:

2. Some tropisms are controlled by hormones.

3. Cells grow faster in areas where auxin is concentrated.

4. Hormones help buds form and grow in the winter.

Explanation:

1. Cutting stems doesn't stimulate hormones to start lateral leaf growth, actually, a hormone named auxin starts promoting cell elongation and the cells there grow larger than the corresponding cells. Hence, this statement is False.
2. Tropisms are controlled by a hormone called auxin. It allows plants to seek out the best conditions for survival. Hence, this statement is True.
3. Auxin is the hormone involved in cell elongation and thus higher concentration promotes cell growth. Hence, this statement is True.
4. A hormone named abscisic acid (ABA) induces bud dormancy during winter. Hence, this statement is True.
5. Auxin and cytokinin both hormones are critical for plant growth. Hence, this statement is False.

Answer 2

Answer:

2. Hormones are in charge of some tropisms.

3. Cells develop more quickly in locations where auxin is abundant.

4. Hormones aid in the formation and growth of buds during the winter.

Explanation:

• Cutting stems does not trigger hormones to initiate lateral leaf growth; instead, a hormone called auxin promotes cell elongation, causing the cells to grow larger than the cells around them. As a result, this assertion is untrue.
• Tropisms are regulated by the hormone auxin. It enables plants to seek out the greatest survival conditions. As a result, this assertion is correct.

• Auxin is a hormone that encourages cell elongation, hence a larger concentration encourages cell growth. As a result, this assertion is correct.
• During the winter, a hormone called abscisic acid (ABA) causes buds to go dormant. As a result, this assertion is correct.
• Auxin and cytokinin both hormones are critical for plant growth. As a result, this assertion is untrue.
