Seeds - Structure and Germination
Types of seeds and their structures
Germination is the process during which seed reserves present in the seed are broken down and the embryo starts to grow.
During germination, the seed absorbs water. Germination is irreversible i.e. once begun; the seed cannot be brought back to dormant state,
Seeds which do not germinate even after provided with all the conditions necessary for germination are called dormant seeds and the phenomenon is termed as dormancy.
Let us study what happens during germination
When a seed is germinating, the portion above the cotyledon that forms future shoots is called plumule and the portion below the cotyledon that forms the future roots is called radicle.
Conditions Necessary for Germination
As shown in the figure, take a beaker with water and place it in, a glass slide with three bean seeds tied to it.
