Hint: A variety of bundles are produced by polyadelphous stamens of flower in which filaments are joined while the anthers remain free.
Complete Answer:
- Androecium comprises a variety of stamens that are the flower's male reproductive organs. A stamen is made of a stalk called anther, like a filament and a flattened globoid tip. The anther produces pollen grains within the anther.
- A flower's stamens remain free or unified with one another. The condition in which all a flower's stamens are free is considered polyandrous. The stamens in the flowers are unified in numerous forms which give rise to a variety of conditions.
Now, let us find the solution from the options-
A flower's androecium can have a differing degree of fusion among filaments and anthers. When multiple bundles are joined to shape the filaments of the stamens, the situation is called polyadelphous.
-Lemon displays stamens that are polyadelphous.
- Gram indicates diadelphous stamens. Thus, option B is not the correct option.
- Syngenesious stamens are revealed by the sunflower. Thus, option C is not the correct option.
- Cotton displays stamens that are monadelphous. Thus, the option D is not the correct option.
Thus, the correct answer is option (A) Lemon.
Note: Monadelphous stamens in which a single bundle is produced by filaments of all stamens, however the anthers are separate, e.g. cotton. Diadelphous stamens in which two bundles are formed joined by filaments and anthers are free, e.g. Grams.
