Aside from defects in the seed the environment that the seed finds itself in has much to do with it. Soil, water, sunlight and temperature must be with tolerable limits for a seed to germinate.
Ultimate, evolutionary, reasons have to do with the fact that many organisms have an R strategy where many potential progeny are propagated because only a few will survive under the conditions they may live in.
Kentucky coffee tree takes a long time to germinate because of the thick seed head. If you take a file, score the seed head and it will sprout faster. This is called scarification.
When a seed begins to grow/sprout it is known as germination.
During seed germination embryo in a seed grows. As a result a small seedling comes out of the seed.
Some species do and some species don't. All species need their seeds to be in their own type of environment to germinate.
To germinate is to begin life, as in "the tomato seed germinated and grew into a tomato plant."

in late spring,sunflower seed will germinate
A mango seed will not germinate if it is coated with pomade. This will prevent the seed from germinating and growing.
you need one cup of water to germinate a seed
During seed germination embryo in a seed grows. As a result a small seedling comes out of the seed.
No, because sunlight can not reach a seed when it is in the soil, but plants still germinate.
Water triggers the enzymatic activities in the seed. Therefore, in the absence of water seed will not germinate for want of enzymatic activities.
It does not germinate
No
The seed will germinate if placed in soil, watered, and placed in the sunshine
no. its dead.
