For seed germination, water and air are essential. Water activates the seed’s growth processes, and air provides oxygen necessary for cellular respiration. Sunlight is not universally required for all seeds to germinate; some seeds need light to sprout, while others germinate in darkness. The necessity of sunlight depends on the specific type of seed. Therefore, while water and air are critical for all seeds, the role of sunlight varies depending on the seed’s requirements for successful germination.
