A botanist observes a dormant seed with no visible growth or movement. How can the botanist determine whether the seed is alive?
Monitor its internal metabolic activity
Visible growth or movement is not a reliable sign of life in a dormant seed, since dormancy is a resting stage where outward activity is minimal.
Life is better confirmed by checking internal metabolic activity, such as respiration and enzyme action, which continue at a low rate even in dormant seeds.
Hence, monitoring its internal metabolic activity is the correct way to determine whether the seed is alive.
