Verified
Embryonic plants are nourished by nutrients in endosperm and the ____, but not by nutrients in fruits.
A) cotyledons
B) seed coat
C) germ
D) bran
E) ovary wall
Cotyledons
The first leaves that appear from a germinating seed, providing energy to the young plant before true leaves develop.
Endosperm
A tissue produced inside the seeds of most flowering plants following fertilization, which nourishes the developing embryo.
Embryonic Plants
Early stage plants developing from embryos, typically within seeds before germination.
- Detail the mechanisms underlying seed development and its eventual germination.
- Understand the nutritional aspects of seeds and their importance in human diet.

Final Answer :
A
Explanation :
Embryonic plants are nourished by the cotyledons, which are part of the seed that contains nutrients for the developing plant. The seed coat protects the embryo but does not provide nutrients for it. The germ is another term for the embryo itself. Bran is the outer layer of a cereal grain and is not involved in embryonic plant development. The ovary wall surrounds the seed but does not provide nutrients for the embryo. Fruits are the mature ovaries of plants and are not directly involved in embryonic plant nourishment.
