Which factor is NOT critical for seed germination?

Warmth
Pressure
Moisture
Oxygen

The correct answer is: Pressure

For seed germination, the essential conditions include warmth, moisture, and oxygen. These elements work together to initiate the metabolic processes necessary for a seed to sprout and grow into a plant. Warmth activates enzymes that facilitate the growth of the seed, making it more responsive to the presence of moisture and oxygen. Moisture is crucial, as it helps soften the seed coat and allows the seed to imbibe water, an essential process for germination. Oxygen is vital for respiration; seeds require it to convert starches and reserves into the energy needed for germination and growth. Pressure is not typically recognized as a critical factor for seed germination. While certain situations may involve physical pressure due to soil compaction or other environmental factors, these do not directly influence the fundamental biological processes required for a seed to germinate. Thus, pressure is the factor that is not critical for seed germination.
