Detailed explanation-1: -Light on the soil is not necessary for seed germination because warmth, water, and oxygen are the only conditions necessary for a seed to germinate.
Detailed explanation-2: -Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don’t confuse seed light requirements with what seedlings need. All seedlings require sunlight.
Detailed explanation-3: -Seeds need both moisture and warmth to germinate-but not too much. Warm up the soil before sowing your seeds.
Detailed explanation-4: -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-5: -Hence, the given statement is ‘True’.
