Detailed explanation-1: -So, the correct answer is ‘Light’.
Detailed explanation-2: -Light is not necessary for a seed to germinate, no. The majority of seeds grow most effectively in the dark. Light, which is essential for seedling growth, may actually hinder the germination process. The three primary and necessary conditions for a seed to germinate are water, oxygen, and temperature.
Detailed explanation-3: -There are four environmental factors that affect seed germination: Water, Light, Oxygen, and Heat.
Detailed explanation-4: -Light is also an important signal for seed germination and seedling development. Many plants, such as lettuce, show photoblastic seed germination, requiring light exposure for germination (e.g. Borthwick et al., 1954).
