how do unisexual plants reproduce?
Unisexual plants are the ones in which male and female flowers are formed on separate plants. These plants require cross pollination for reproduction. So, for reproduction to occur, pollen grains from a male flower should be transferred to the stigma of the female flower.
Once the pollen are transferred to the female flower, the ovule present in the ovary of the flower gets fertilized resulting in the formation of embryo (inside seeds) and fruit development takes place. The seeds present in the fruit can give rise to offsprings when suitable conditions are provided.
