The germ of a grain contains all of the following except:
A
Proteins
B
Vitamins
C
Starch
D
Lipids
Verified step by step guidance1
Understand the structure of a grain, which typically consists of three main parts: the bran, the germ, and the endosperm.
Recall that the germ is the reproductive part of the grain that can grow into a new plant and is rich in nutrients such as proteins, vitamins, and lipids.
Recognize that starch is primarily found in the endosperm, which serves as the energy reserve for the seed, rather than in the germ.
Compare the nutrient composition of the germ with the options given: proteins, vitamins, lipids, and starch.
Conclude that since starch is not a component of the germ but rather the endosperm, it is the correct answer to the question.
