dormancy
They protect the seed to not get damage before it germinates
The difference is that the bean seed germinates by dicots and the corn seed germinates by monocots.
The plant-seed germinates well in burned soil
When a plant starts to grow from a seed we say the seed germinates.
When a monocot seed germinates a single leaf is produced. Two seed leaves are produced with a dicot germinates.
A seed derives its food from the cotyledones or endosperm during germination
You do not have a lawn until the seed germinates. If the soil is very dry water two or three days before sowing. If conditions are normal sow the seed and then water well and leave alone until the seed germinates.
yes.
A seed germinates when it is in a favorable condition, and thus begins to grow a root and a seed leaf. As these two parts continue to grow, the leaf will eventually poke through the soil.
You need to plant it.
If you mean cotyledon, then that is part of the embryo inside of a seed. When the seed germinates it forms the first "leaf" of the plant.
A poinsettia plant is a dicot. This means that it has two seed leaves (cotyledons) when the seed germinates.
