2. Why is it an advantage that most seeds go through a stage of dormancy before germination?

so it doesnt germinate in bad conditions and still preserve enough energy to germinate when the time is right, so to speak, also in keeps all the seeds from germinating a once which is why its so hard to get rid of weeds...

Can a seed grow without germination?
Yes you can germinate a seed without it being covered as long as it receives sufficient moisture during germination. Normally small (or extremely small) seeds are germinated without covering (e.g. begonia). Note some seeds do require darkness for germination.
What survival mechanisms have plants developed?
plants have developed varius types of seed Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, when the probability of seedling survival is low. One important function of most seeds is delayed germination, which allows time for dispersal and prevents germination of all the seeds at same time. The staggering of germination safeguards some seeds and seedlings from suffering damage or death from short periods of bad weather or from transient herbivores; it also allows some seeds to germinate when competition from other plants for light and water might be less intense. Another form of delayed seed germination is seed quiescence, which is different than true seed dormancy and occurs when a seed fails to germinate because the external environmental conditions are too dry or warm or cold for germination. Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination. i got this info from wikipedia
About seed germination?
Cocoa seeds like to be in moist sphagnum moss for germination to take place. The seeds need to soak before they can be germinated.
Do thick seed coats get cracked before germination?
Yes
What happens to starch before it is used for germination?
It has to be turned into a sugar, such as sucrose.
How is germination promoted after a period of dormancy?
This depends on the type of seed. Providing the right conditions for the type of seed is vital. For instance most alpine seeds require a period below zero before they will germinate.

Period of rest before the seed germinates?
dormancy

Does the storing of a seed before germination effect the germination of the seed?
Yes because of Lauren Hallas.
Does the type of seed matter for germination?
Seeds from different plants have different requirements for germination. Some require more moisture or less moisture or will sprout in water, They may need different temperatures to germinate. Some seeds require a period of dormancy while something happens to the embryo internally. Some require a period of wetness to soften a hard outer shell or a period of cold or freezing weather before it will sprout.

Yes

When does germination in a plant begin?
Plant germination begins when the seed has all the required conditions ( like optimum temperature, pH, water etc. ) before losing it's viability.
Do you soak lima beans before growing them?
yes you do, it speeds up the germination time
Why do some seeds need to be put into a freezer before germination?
because the require a cold period (near freezing) to "break" the seed's dormancy. the process of putting the seed (or sometimes bulbs) in a fridge mirrors the over-wintering conditions that normally occur during winter. this is used to sometimes fool plants into believing that they should start to initiate germination (or sprouting), and is a mechanism used to produce these plants out of season. the process is also used in the seed production industry, where seed for the northern hemispheres summer season may be grown in the southern hemisphere, they then chill the seed to "fool" it into believing it is the new growing season before shipping it to the northern hemisphere.
