Question

Select the following statements that are true for insect pollinated flowers from the given options.

• Majority of these flowers are large, colourful and rich in nectar.
• Nectars and seeds are usual floral rewards to attract insects for pollination.
• Pollen grains of these flowers are generally mucilaginous so as to stick to the body of the insects.
• A foul odour is emitted by some flowers to attract flies and beetles.

Choose the correct answer:

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (iii) and (iv)
• D. (i), (iii) and (iv)

Hint:

Insect pollinated flowers are typically showy, fragrant or odorous, and produce sticky pollen to ensure effective pollination.

Answer 1

The Correct Option is D

Statements (i), (iii), and (iv) are true:

• (i) Insect pollinated flowers are often large, colourful, and produce nectar to attract pollinators.
• (iii) Their pollen grains are sticky and mucilaginous, allowing them to adhere to insect bodies.
• (iv) Some flowers emit a foul odour to attract specific pollinators like flies and beetles.

Statement (ii) is incorrect because seeds are not a floral reward; nectar and pollen serve that purpose.
