Agents of Pollination & Pollen Production — NEET Biology
📚 Practice ConceptAgents of Pollination: Plants use two abiotic (wind and water) and one biotic (animals) agents to achieve pollination. Majority of plants use biotic agents for pollination. Only a small proportion of plants use abiotic agents. Pollen grains coming in contact with the stigma is a chance factor in both wind and water pollination. To compensate for this uncertainties and associated loss of pollen grains, the flowers produce enormous amount of pollen when compared to the number of ovules available for pollination.
Assertion (A): Wind and water pollinated plants achieve successful reproduction despite uncertainties. Reason (R): These plants produce enormous amounts of pollen to compensate for losses during dispersal.
View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
NCERT confirms wind/water pollination can be successful despite being less precise - Assertion true. NCERT states “To compensate for this uncertainties and associated loss of pollen grains, the flowers produce enormous amount of pollen when compared to the number of ovules available for pollination.” The Reason explains HOW success is achieved despite uncertainties.
