  • wind pollinated plants
  • insect pollinated plants
  • bird pollinated plants
  • bat pollinated plants
  • Correct Option: B  [ insect pollinated plants ]

    Remark:

In angiosperm, the haploid, diploid and triploid structures of a fertilized embryo sac sequentially are:

NEET-2023 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • Synergids, antipodals and Polar nuclei
  • Synergids, Primary endosperm nucleus and zygote
  • Antipodals, synergids, and primary endosperm nucleus
  • Synergids, Zygote and Primary endosperm nucleus
  • Correct Option: D  [ Synergids, Zygote and Primary endosperm nucleus ]

    Remark:

What is the function of tassels in the corn cob?

NEET-2023 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • To protect seeds
  • To attract insects
  • To trap pollen grains
  • To disperse pollen grains
  • Correct Option: C  [ To trap pollen grains ]

    Remark:

Given below are two statements:
Statement I: Cleistogamous flowers are invariably autogamous.
Statement II: Cleistogamy is disadvantageous as there is no chance for cross pollination.
In the light of the above statements, choose the correct answer from the options given below :

NEET-2022 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • Both Statement I and Statement II are correct
  • Both Statement I and Statement II are incorrect
  • Statement I is correct but Statement II is incorrect
  • Statement I is incorrect but Statement II is correct
  • Correct Option: A  [ Both Statement I and Statement II are correct ]

    Remark:

Identify the incorrect statement related to Pollination:

NEET-2022 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • Pollination by water is quite rare in flowering plants
  • Pollination by wind is more common amongst abiotic pollination
  • Flowers produce foul odours to attract flies and beetles to get pollinated
  • Moths and butterflies are the most dominant pollinating agents among insects
  • Correct Option: D  [ Moths and butterflies are the most dominant pollinating agents among insects ]

    Remark:

Which part of the fruit, labelled in the given figure makes it a false fruit?

NEET-2022 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • A → Mesocarp
  • B → Endocarp
  • C → Thalamus
  • D → Seed

  • 8-nucleate and 7-celled
  • 7-nucleate and 8-celled
  • 7-nucleate and 7-celled
  • 8-nucleate and 8-celled
  • Correct Option: A  [ 8-nucleate and 7-celled ]

    Remark:

The term used for transfer of pollen grains from anthers of one plant to stigma of a different plant which, during pollination, brings genetically different types of pollen grains to stigma, is :

NEET-2021 [Sexual-Reproduction-in-Flowering-Plants] [class-xii ]

  • Xenogamy
  • Geitonogamy
  • Chasmogamy
  • Cleistogamy
  • Correct Option: A  [ Xenogamy ]

    Remark:
