262557 Assertion (A) :In some plants the generative cell divides and forms the two male gametes during pollen tube growth in stigma.
Reason (R) : In plants which shed pollen in three cell stage, the pollen tube will have two male gametes from the beginning.
The correct option among the following is
Options:

1 (A) is true, (R) is true and (R) is the correct explanation for \((\mathrm{A})\)
2 (A) is true, (R) is true but (R) is not the correct explanation for \((A)\)
3 (A) is true but ( \(R\) ) is false

262531 Which of the following statements is not correct

1 Some reptiles have also been reported as pollinators in some plant species
2 Pollen grains of many species can germinate on the stigma of a flower, but one pollen tube of the same species grows into the style
