Germination Explained


      Germination is the process in which the plant starts to grow out of the cell and begins to grow. To start this process, the plant needs to go through imbibition which is when the water starts to soften the hard protective shell of the seed. Then the plant is able to swell up and split the seed open so it can begin growing and get water to the embryo.

Seed Structure and Function

Monocot seed
Dicot seed
 
                   

     The endosperm will supply the food for the baby embyo

      The Cotyledon is the part of the embryo that digests the endosperm      and feeds the embryo      

      The embryo is the the actual baby and will grow into a plant

The dicot does not have endosperm because it is dissolved in the 2 cotyledons
