During sexual reproduction in Angiosperms (flowering plants), the sequence of development starting from the female gamete is as follows: The haploid egg cell fuses with a haploid sperm cell during fertilization to form a diploid zygote. The zygote undergoes mitotic divisions and differentiation to develop into a multicellular embryo. The embryo is contained within the seed, which develops from the ovule after fertilization. Therefore, the correct sequence is Egg → zygote → embryo → seed.

The developmental sequence after fertilization in flowering plants is Egg + Sperm → Zygote → Embryo → Seed.

The seed is a mature ovule, and the fruit is a mature ovary, both developing after fertilization and containing the embryo within the seed.
