The process of pollen from one plant fertilizing ovules on a different plant is called

• A. Self-pollination
• B. Fertilization
• C. Hybrid
• D. Cross-pollination

Answer: (D)

Cross-pollination. When pollen from a different plant reaches and fertilizes the ovules of another plant, the transfer comes from a distinct individual, not the same plant. This contrasts with self-pollination, where the pollen and ovules come from the same plant. After pollen lands on a compatible stigma, fertilization can occur when the sperm fuses with the egg inside the ovule, leading to seed formation. A hybrid is what you get after crossing different varieties or species, not the process itself.
