Assertion (A) : Herkogamy is common in Datura plants. Reason (R) : In Herkogamy, anther and stigma are placed at different positions so that the pollen can't come into contact with the stigma of the same flower. Which of the following is true?
1 Both (A) and (R) are true and (R) is the correct explanation of \((A)\)
2 Both \((\mathrm{A})\) and \((\mathrm{R})\) are true, but \((\mathrm{R})\) is not the correct explanation of (A)
3 (A) is true, but (R) is false
4 (A) is false, but (R) is true
Explanation:
Herkogamy is known as the process in which pollination of pollen with the stigma of the same flower is prevented by the means of mechanical separation. This occurs in bisexual flowers. Herkogamy, the spatial separation of anthers and stigmas within flowers, is a key floral trait though to promote outcrossing or the avoidance of interference between male and female sexual functions (Wee and Lloyd 1986).
