Starch agar plates amylase experiment

Webb13 apr. 2012 · Amylase plays a vital role in the growth of plants. In order for the hydrolysis of starch to become maltose amylase is needed to catalyse it. The effects of this can be seen in the experiment involving the starch agar plate and the raw seeds. The starch that is in the agar plates is digested by the amylase that is produced in the seed.
