Which process is essential to sexual propagation in flowering plants, leading to seed production?

• A. Grafting
• B. Clonal propagation
• C. Fertilization processes
• D. Tissue culture

Answer: (C)

Fertilization enables sexual propagation in flowering plants by combining genetic material from two gametes to produce seeds. In a flower, pollen from the male parts lands on the stigma and grows a tube down into the ovule. When the sperm reach the ovule, one sperm fuses with the egg to form a zygote, while another sperm fuses with the central cell to form the endosperm. This double fertilization results in a developing embryo inside a seed, with nourishment provided by the endosperm, ready to disperse and grow into a new plant. The other methods listed reproduce plants without involving fertilization or seed creation, instead using vegetative parts to make clones, so they don’t achieve sexual propagation.
