The volume of dry seed increased by imbibitions is _ times.
Correct answer: B. 200 times
- A. 100 times
- B. 200 times
- C. 300 times
- D. 150 times
Explanation
The correct answer is "200 times." During the process of imbibition, seeds absorb a significant amount of water, causing their volume to increase substantially, typically around 200 times. This expansion is essential for breaking the seed coat, allowing germination to proceed. Option A (100 times) and Option D (150 times) underestimate the typical increase, while Option C (300 times) overestimates the increase.

About Forms and Functions of Plants
Plant nutrition and transport cover mineral uptake, photosynthesis, xylem movement of water and minerals, and phloem translocation of sugars. Plant growth regulators include auxins, gibberellins, cytokinins, abscisic acid and ethene, whose effects on cell division, elongation, dormancy, fruit ripening and tropic responses should not be confused with mineral nutrition.
