Detailed explanation-1: -Light, water, oxygen, and temperature are essential conditions for seed germination.
Detailed explanation-2: -The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
Detailed explanation-3: -So, the correct answer is ‘Oxygen, moisture and suitable temperature’
Detailed explanation-4: -Seeds require a certain temperature in order to germinate. Each plant has a specific optimum and a range within which germination will occur. The closer the temperature is to optimum, the quicker germination will occur. Most seeds germinate when the soil temperature is between 68° and 86°F.
Detailed explanation-5: -Temperature affects germination in three primary ways: moisture, hormone production, and enzyme activity. For seeds to germinate, they need to imbibe water. For this to occur, sufficient moisture must be present. A warmer climate may increase evaporation and decrease moisture, which would negatively affect germination.
