Buried deep inside is the tiny plant itself, this is known as the embryo or germ. Tho tiny now, this small thing will grow into a simple-minded flower or a large tree. Attached to the cotyledons are two structures. During germination, beneath the cotyledons is the hypocotyle, the tip pf this is called the radical.



The radical is the first to break out of the seed coat and the first true root of the plant. Below the cotyledons is the epicotyl, which produces the stem and leaves.

        Before you learn about the handle of germination, you have to know just where the seed comes from and just how the turn works. First the pollen from the anthers grip onto the stigma of the flower. The pollen tube grows down through the pistil, this pollen tube is the passage way for...
