Concept:A seed is a mature ovule containing an embryo, stored food, and a protective coat.
Explanation:The seed of a flowering plant consists of three essential parts: the embryo, a food reserve (endosperm or cotyledons), and a seed coat.
The embryo is the young plant that develops after germination.
The food reserve provides nutrition for the embryo until it can photosynthesize.
The seed coat (testa) protects the internal structures from damage and desiccation.
Option A (Ovary and ovary wall) refers to the fruit, not the seed itself.
Option C (Cotyledons) are part of the embryo or food storage, but not the complete seed.
Option D (Zygote) is the fertilized egg that becomes the embryo, but the seed includes more than just the zygote.
Answer:Embryo, food reserves and coat
