Question

Identify the wrong matching

• A. \({Self-Sterility - Gloriosa}\)
• B. \({Herkogamy - Hibiscus}\)
• C. \({Protandry - Sunflower}\)
• D. \({Protogyny - Datura}\)

Hint:

Self-Sterility, also called self-incompatibility, prevents self-pollination and promotes cross-pollination. Examples include Petunia and Brassica, but not Gloriosa.

Answer 1

The Correct Option is A

Step 1: Understanding the Terms 
Self-Sterility (Self-Incompatibility) refers to the inability of a flower to fertilize itself, preventing self-pollination. 
However, Gloriosa does not exhibit self-sterility, making this an incorrect match. 
Herkogamy is a structural adaptation in flowers where physical barriers prevent self-pollination. 
It is seen in Hibiscus, making this a correct match. 
Protandry is when the male reproductive part (anther) matures before the female part (stigma), promoting cross-pollination, as seen in Sunflower. 
Protogyny is when the female reproductive part (stigma) matures before the male part (anther), promoting cross-pollination, as seen in Datura. 
Step 2: Identifying the Incorrect Match 
Since Gloriosa does not exhibit self-sterility, the incorrect match is (1) Self-Sterility - Gloriosa.
