The transfer of pollen grains from the anther to a sigma is

Step 1: Analyze the question The question asks for the term describing the movement of pollen grains from the anther (male part) to the stigma (female part) of a flower. (Note: "sigma" in the question is a typo for "stigma".)

Step 2: Explain the concept In flowering plants, reproduction involves these key stages:

• Pollination: the transfer of pollen grains from the anther to the stigma.
• Fertilization: the fusion of the male gamete (from the pollen tube) with the female gamete (egg cell) in the ovule.
• Placentation: the arrangement of ovules within the ovary.
• Propagation: the multiplication of plants, either sexually (by seeds) or asexually (by cuttings, tubers, etc.).

Step 3: Evaluate each option

• A. Propagation: This is general plant multiplication, not specifically pollen transfer. ✗
• B. Placentation: This describes how ovules are attached inside the ovary. ✗
• C. Pollination: This is exactly the transfer of pollen from anther to stigma. ✓
• D. Fertilization: This happens after pollination, when gametes fuse. Pollen landing on the stigma is not yet fertilization. ✗

Step 4: Answer The correct option is C. Pollination.

Tip: Remember the order: Pollination comes before Fertilization (P before F, as in the alphabet backwards, or just think "pollen travels first, gametes fuse later"). Also note that pollination can be self-pollination (same flower or same plant) or cross-pollination (different plants of the same species), and agents include wind, insects, water, and animals. JAMB often tests these distinctions.
