3. Life cycle of funaria

4. Oogamus. Multicelluler and jacketed sex organs. Sex organ present on gametophyte. Antheridium club shaped, Archeganium flask shaped. Antheridium has androcyte mther cell undergo mitosis and form antherozoids,and enter into archegoium by chemotactic movement through water. After syngamy zygote develop into embryo holoblastic and exoscopic on gametophyte. Embryo develops into sporophyte.that depends upon gametopyte for nutrition. Sporophyte has foot, seta, capsule. Spores are formed by meiosis spores are homosporus.

5. By death and decaying of capsule in riccia. By pseudoelater in anthoceros. By elator in marchantia. By peristome teeth in funaria(elaborate method of spore dispersal). Elator : elongated diploid structure, hygroscopic in nature.

6. Largest bryophyte

7. Foliose mass having largest archegonia of plant kingdom

8. Peat mass, bog mass.

10. Libration of spore by pseudoelator. It has pyrenoids. Have foot seata but no capsule. Saprophytic.

11. Riccia fluitans, Ricciocarpus notans, Riella are aquetic.
