I'm no expert but I think this might help:

From: http://www.answers.com/topic/epigeal In botany, a seed is described as epigeal when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The converse, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal. And http://www.answers.com/topic/cotyledon Cotyledons may be either epigeal, expanding on the germination of the seed, throwing off the seed shell and become photosynthetic above the ground; or hypogeal, not expanding, remaining below ground and not becoming photosynthetic. The latter is typically the case where the cotyledons act as a storage organ, as in many nuts and acorns.

So as the seed of oil seed crops does not act as a storage organ, they are typically epigeal in nature.

yes it does. the less light the seed has will either make the seed take longer to germinate or not germinate at all. Answer it really depends on the type of seed. some seeds like watermelon and tomato coulnd care less about how much light they get while others like lettuce would not germinate in the dark at all. but as a rule of thumb, most seeds prefer to germinate in the dark.

The seed would not germinate at all in the freezer and the water used for planting the seed would turn into ice.

It is because the seed might be too old or you overfed the plant and that is why it did not germinate

All you need for seed germination is warmth and moisture. The proper germination supplies will make it much easier to germinate your seed.

Seed germination is significantly affected by temperature. When it is cool, seeds are slower to germinate than when it is warm. If conditions are too cool or too hot, seeds won't germinate at all.
