Starch agar can be described or explained as a differential medium that tests the ability of an organism to produce certain exoenzymes, including a-amylase and oligo-1,6-glucosidase, that hydrolyze starch.
It should be understood that, the inclusion or addition of starch makes it a rich medium for those bacteria possessing the enzyme alpha-amylase, which breaks starch down to its component glucose molecules.
Therefore, in this case, any plant embryo that does not contain starch will be unable to grow.
Answer: The atom of carbon is able to form macromolecules because it has only four electrons in its outer shell. This is the reason why it can bond with four other carbon atoms. The bonds that it forms with other carbon molecules are very stable.
Explanation: I did my research and i also took Science class. :)
