Sexual Reproduction in Flowering Plants

Assertion: Insects visit flower to gather honey. Reason: Attraction of flowers prevents the insects from damaging other parts of the plant.
1 If both assertion and reason are true and reason is the correct explanation of assertion
2 If both assertion and reason are true but reason is not the correct explanation of assertion
3 If assertion is true but reason is false
4 If both assertion and reason are false
Explanation:
Insects visit flower to gather nectar not-honey and get a coating of pollen grains of the flower, which are generally sticky. These pollen grains are dusted off when they come in contact with a stigma. Attraction of flowers cannot prevent the insects from damaging other parts as only those insects are attracted to the flowers which help in pollination.

The following is not related to the events of pollen pistil interaction
1 Formation of pollen tube
2 Germination of pollen grain on stigma
3 Formation of zygote as a result of syngamy
4 Growth of pollen tube through style and reaching the ovule
Explanation:
Steps of pollen-pistil interaction :- - Landing of true pollen on the compatible pistil. - Germination of pollen and formation of pollen tubes. - Pollen tube growth through style of the pistil towards the ovary. - Entry of male gametes into the ovule and then to synergid.

1 wind pollinated plants
2 insect pollinated plants
3 bird pollinated plants
4 bat pollinated plants
Explanation:
Pollen from insect - pollinated flowers i.e. frequently sticky and heavy with a rough surface that makes it easy for them to attack to insects. - Flowers also have pleasant nature that attracts insects that pollinate the flowers by moving from flower to flower. - Flowers are brightly colored scented and secrete nector Ex. Rose, Papaya, Sun-flowers.
