Which term describes pollen transfer from the same plant to its stigma?

• A. Pollination
• B. Self-pollination
• C. Cross-pollination
• D. Fertilisation

Answer: (B)

Self-pollination is pollen transfer from the same plant to its own stigma. This happens when pollen from the stamens lands on the stigma of the same plant, either within the same flower or between flowers on the same individual. It’s different from general pollination, which just means pollen reaching a stigma, and from cross-pollination, which is pollen transfer between different plants. Fertilisation comes after pollination and is the process where the pollen nucleus fuses with the egg to form a zygote. Self-pollination can occur in plants that don’t rely on outside pollinators as much, but it tends to reduce genetic diversity compared to cross-pollination.
