Question

multiple choice question
in angiosperm seeds, what structure protects the developing embryo and its food supply?
seed coat
sepals
cotyledon
endosperm

Explanation:

• Seed coat: It is the outer protective layer of the seed. It safeguards the developing embryo and the food supply (endosperm or cotyledons) from physical damage, pathogens, and desiccation.
• Sepals: These are part of the flower. They protect the flower bud before it opens but have no role in protecting the seed embryo and its food supply.
• Cotyledon: It is part of the embryo. In some plants, it stores food (as in dicots where it absorbs food from endosperm during seed development), but its main function is not protection.
• Endosperm: It is the food - storage tissue. It provides nutrients to the developing embryo but does not protect the embryo and itself.

Answer:

seed coat
