Question

For wind pollination, which structure of flower would be more pronounced?

• A. VII
• B. I and VI
• C. II, III, IV, and V
• D. II, V, and VII
• E. III and VII

Answer 1

The correct option is C II, III, IV, and V

Sepals (VI) and petals (I) are parts of accessory whorls of a flower and serve to attract pollinators. A stamen consists of anther (III) and filament (IV). Anther is a broad knob part of stamen that contains two long and cylindrical microsporangia in its lobes. Carpel is the female part of flower derived from central region of thalamus and consists of stigma (II), style (V) and ovary (VII). Wind pollinated plants produce large quantitites of dry, small pollens in big anthers (III) of plain flowers (no showy sepals and petals). The staman filament (IV) is well developed to withstand strong wind currents while well adapted style (V) and stigma (II) ensure capturing of maximum number of wind pollinated pollens. Correct answer is 'C'.
