Question

Transfer of pollen grains from anther to stigma of the same flower is called _____.

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

Hint:

Self-pollination occurs within the same flower or same plant, while cross-pollination occurs between different plants.

Answer 1

The Correct Option is B

Concept: Pollination is the process of transfer of pollen grains from the anther to the stigma in flowering plants. Pollination is mainly of two types:
• Self-pollination
• Cross-pollination

Step 1: Understanding self-pollination. When pollen grains are transferred from the anther to the stigma of:
• the same flower, or
• another flower on the same plant, the process is called: \[ \boxed{\text{Self-pollination}} \]

Step 2: Understanding why other options are incorrect.
• Option (1) Cross-pollination: This occurs between flowers of different plants of the same species.
• Option (3) Fertilization: Fusion of male and female gametes after pollination.
• Option (4) Propagation: General process of reproduction in plants. Hence, the correct answer is: \[ \boxed{(2)\ \text{Self-pollination}} \]
