What happens when a pollen grain fertilizes an ovule?

• A. Ovule develops into a seed
• B. Pollen grain becomes fruit
• C. The embryo begins to grow
• D. Flower wilts

Answer: (A)

When a pollen grain fertilizes an ovule, the ovule is set to become a seed. In flowering plants, fertilization produces a zygote from the egg cell, and the ovule develops around that zygote to form a seed that contains the developing embryo and stored nutrients. The surrounding ovary typically matures into fruit to help disperse the seeds. So the direct outcome of fertilization of the ovule is seed formation, not the pollen grain turning into fruit or the flower wilting.
