The condition in which the male reproductive organs (stamens) of a flower mature before the female ones (pistil), thereby ensuring that self-fertilization does not occur.
Protandry is a condition by which a male reproductive or the stamens of a flower mature before the female part of the flower or the carpels of a flowering plant of the same species, thereby ensuring that self-pollination does not take place
The correct answer is D.... Because if a flower is protandrous then self pollination is unlikely, it needs either cross pollination or should be pollinated by an insect....or am I wrong???
this is wrong, if a flower is protandrous then it is an hermaphrodite which makes it unis*xual so the answer is A
