The three main types of bryophytes consist of the liverworts, mosses, and hornworts, each of which encompasses several hundred different species. As gametophytes, hornworts are similar to a liverworts thallus growth form. The remainder of liverworts are thallus. They have microscopic structures in all shapes and sizes that likely aid in the diffusion of water across the surface. The introductory WHAT IS A BRYOPHYTE? (51 Agility required) We also offer a complete line of accessory products for growing moss gardens or lawns, as well as an extensive collection of . sperm is far more expensive to produce than eggs. These help differentiate species. Depending on the genus, hornworts grow in either a branching or circular pattern.However, hornworts show no differentiation among cells throughout the gametophyte generation. 6. Beyond their impact on general ecology, species of bryophytes have proven to be beneficial to humans. Even the largest moss only grows to 50cm tall but much larger colonies of bryophytes can often be found. order: Tetraphidales (3 families, 4 genera, no more than about 50 species). Furthermore, rhizoids perform the function of roots, essentially anchoring the plants into the surface. The full distribution of many common bryophyte species in the state remains incomplete due to a lack of field investigation. hypothesis of male rarity: cost of sex..
