The correct sequence of reproductive stages occurring in flowering plants is:(a) gametes, zygote, embryo, seed (b) zygote, gametes, embryo, gametes(c) seed, embryo, zygote, gametes (d) gametes, embryo, zygote, seed
Correct Answer: (a) gametes, zygote, embryo, seed
Explanation:
In flowering plants, during reproduction, two different gametes fuse with each other to form a zygote. This zygote undergoes multiple division and forms an embryo. The embryo grows and develops into a seed.
