Detailed explanation-1: -Germination-pollination-fertilization-seed dispersal.

Detailed explanation-2: -Pollination leads to fertilization after which an embryo is formed. The embryo undergoes several developmental stages and finally forms a seed. The seed germinates to form a seedlingor new plant. Hence, the correct sequence is pollination, fertilisation, embryo, seedling/new plant.

Detailed explanation-3: -The sequence of reproductive stages in the plant: gamete formation (ovule and pollen), pollen reaches the stigma of flower (pollination), pollen germinates and forms pollen tube that reaches to the ovary and then male gamete is released. Male gamete fuses with female gamete and forms zygote.

Detailed explanation-4: -The 5 main plant reproduction steps involved in the life cycle are: Seed, Germination of Seeds, Seedling growing to attain maturity, Flowering, Pollinating, Seedling and Seed Dispersion; 2.
