The probability of fruit set in a self-pollinated bisexual flower of a plant is far greater than in a dioecious plant. Explain.

(N/A) In a self-pollinated bisexual flower,the male and female reproductive organs are present within the same flower,ensuring pollination and subsequent fruit set even in the absence of external pollinators.
In contrast,dioecious plants have male and female flowers on separate individuals. This separation necessitates the presence of external pollinating agents (such as wind,water,or insects) to transfer pollen from the male plant to the female plant.
Therefore,the dependency on external factors makes fruit set in dioecious plants less certain compared to self-pollinated bisexual flowers.
