Explanation:
In Funaria, male and female reproductive organs are on the same plant but different branches. Funaria is protandrous i.e., male sex organs mature first. Water is essential for fertilization. The antherozoids reach to archegonial neck and swim down to venter. Any one antheroizoid fuses with egg to form zygote, it becomes oospore. Which divides and redivides to form embryo. Later, the embryo grows into a sporophyte.
