What do seeds need to grow

All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. When seeds are planted, they first grow roots. Once these roots take hold, a small plant will begin to emerge and eventually break through the soil. ... As the plant grows and begins to make its own food from nutrients it takes from the soil, it will grow into a larger plant. The seed itself is like a survival package. Hard seed coats soften when soaked in water or when the soil is consistently moist, but unless there is some way to get water to the seeds, they may die before they ever germinate. ... Thin-coated seeds need water so that they can absorb nutrition from soil.
