The male sex cells,androcytes of bryophytes are motile and require a medium to swim in to reach the female sex organ for fertilisation.Hence water is essential as it becomes the medium for the androcyte to swim.

Asexual reproduction of many bryophytes occur through fragmentation gemmae production archegonial or receptacles?
in bryophytes,the spore producing asexual generation alternates with the gamete producing sexual generation.an example is riccia. all bryophytes are gametophytes (gametes are produced) bryophytes have sex organs-antheridium-producing sperms and archegonium-producing ova. they develop on the plant itself when the plant is mature. sperms are produced.they then fall off from the thallus and be on the ground.then fertilization occurs when water is on plant as well as on ground to facilitate the swimming of sperms.when ova in archegonium is mature the top portion of it opens and sperms come inside.only one sperm fuses wit the ova and produces zygote. it develops an outer wall to disable other sperms coming inside.the zygote undergoes repeated divisions and results in the formation of 4 spores. when suitable conditions come, the spores germinate.as they grow the root-like structures develop and the gametophyte is formed.

Wat is a clitoris?
The clitoris is a sexual organ that is present only in female mammals. In humans, the visible button-like portion is located near the anterior junction of the labia minora, above the opening of the urethra and vagina. Unlike the penis, which is homologous to the clitoris, the clitoris does not contain the distal portion of the urethra, and functions solely to induce sexual pleasure. The only known exception to this is in the Spotted Hyena. In this species, the urogenital system is unique in that the female urinates, mates and gives birth via an enlarged, erectile clitoris, known as a pseudo-penis
