What does a seed contain that provides energy to germinate?

Answer 1

Seeds no matter what size are packages of genetic material and energy that are living in the same way the plant that they came from is/was living. the seeds continue to be living until they start growing. Some plant seeds from some plants and trees can remain viable for 100's of years. That is they can fall from the tree and remain in the soil for a hundred years until the conditions are correct for it to start growing. the correct conditions act like a trigger and then bam, the energy in the seed is released as roots and leaves and then it start absorbing energy from its surroundings. So the answer is seeds get there energy from the parent plant. seeds are a package of genetic material and certain nutrients necesary for the roots and leaves to grow. moisture is often the trigger. Google it!

Answer 2

Generally the seed is provided with an energy or food packet by the parent plant, which in flowering plants is called an endosperm. However some plants, such as some orchid seeds are so small that they include no endosperm and they must form a symbiotic relationship with a fungus which provides energy for the seed. Again, it is a little bit different in gymnosperms, but the overall principle is the same, the parent plant provides the seed with nutrition.

Answer 3

after the food stored in the cotyledons is expended the the sun provides energy through photosynthesis

Answer 4

For many seeds, it gets its energy from stored carbohydrates within the endosperm.

Answer 5

stored food I think by water
