Answer:
The embryo without starch OR cotyledon
Explanation:
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.
