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.

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 seeds need water to grow?
The seeds need nutrients for their growth during development inside the fruit and on ripening & drying they need water for sprouting and germination.
What do most seeds need in order to grow and reproduce?
Seeds need the proper conditions such as temperature .growing medium and moisture to encourage germination. Seeds do not reproduce the resulting plants will reproduce when reaching maturity.
How long does a seed need to be refrigerated before planting?
Yes seeds that have been refrigerated can be planted as long as it was stored in an air-tight container. Otherwise the seed will have dried out, making germination impossible. If you are not certain, try planting them before throwing them away.
Does a seed need direct sun light or not?
Most seeds are damaged by direct sun and the majority need moisture, warmth, and darkness to stimulate growth. A few species of seeds need light to aid germination, but not necessarily direct sun.

Why do seeds need enzymes to convert starch for germination?
digestive track
What conditions that must be right for germination to occur?
It varies somewhat, but seeds generally need a warm moist substrate. So if you sprinkle some radish seeds onto a moist paper towel, put it into a ziplock, and keep it in a warm place, germination is likely to occur. Other seeds have different requirement though-- some seeds need to be partially digested by a bird or mammal before they can sprout. Weird huh?

Does the soaking of seeds affect germination?
of course. controled soaking and drying is used to create primed seeds. the water starts the germination process. of course the root will soon need oxygen so if you keep it soaked it will suffacte and die.

Is sunlight needed for seed germination?
Sunlight is not need to germinate seeds. All that is needed is moisture and the proper temperatures.
What facts affect seed germination?
Heat, moisture, and airflow. Some seeds also need light to germinate.
Why do seeds need sunlight to germinate?
The process by which a parent plant produces a baby plant or seedling is called germination. Seeds need germination because then there will be less plants in the world, like humans do seeds also need germination.
Why do seeds not need sunlight for germination?
Because plants only need sunlight for photosynthesis which produces sugar for it to "eat". Seeds are full of nutrients from their parent plant, that the can grow enough for the cotyledons to find sunlight.
How do you freeze grape leaves?
yes, blanch them first in boiling water for a few seconds before freezing
