During seed dormancy, seeds do not germinate because the seeds
Correct answer: C. Require a period of rest before germination
- A. Are devoid of all kinds of nutrients
- B. Could produce fruits with hard fruit wall
- C. Require a period of rest before germination
- D. Could produce plants that are vulnerable to diseases
Explanation
The correct answer is that seeds require a period of rest before germination (Option C). Seed dormancy is a survival strategy to prevent germination during unfavorable conditions. This allows seeds to remain viable until environmental conditions are optimal for growth. Option A is incorrect because seeds contain nutrients necessary for early growth. Option B is irrelevant as the fruit wall's hardness doesn't affect seed dormancy. Option D is incorrect because dormancy is unrelated to disease vulnerability.

About Plant Growth Regulators
Plant growth regulators are chemical messengers that control growth, development and responses to the environment. The topic covers auxins, gibberellins, cytokinins, abscisic acid and ethylene, including cell elongation, apical dominance, tropisms, seed germination, dormancy, fruit ripening and leaf fall, with growth promoters distinguished from inhibitors.
