Question

Which type of pollen grains are found in insect pollinated flowers?

• A. Smooth and light
• B. Large and sticky
• C. Light and rough
• D. Heavy and coloured

Answer 1

The correct option is B Large and sticky

The insect pollinated flower has pollen grains that are sticky, large and heavy, so that they can cling onto the insect’s body more easily. The pollen grains are also in small quantities, because it is very likely that insects will enter another flower, and the pollen grains would have a higher chance of landing on the stigma. As such, there is no need for production of pollen grain in large quantities.

Thus, the correct answer is option B.
