Liverworts. The liverworts grow usually in moist, shady habitats. The plant body of a liverwort is thalloid, the thallus is dorsiventral and closely appressed to the substrate. Asexual reproduction in liverworts takes place by fragmentation of thalli, or by the formation of specialized structures called.
What type of environment do liverworts thrive in and why?
They are non-vascular plants, and their lack of vascular tissue means they grow flat along the ground. It is also the main reason liverworts prefer moist environments. They can survive very harsh climates, but liverworts typically need to be near freshwater to survive.
Which class of bryophyte is known as liverworts?
While bryophytes have no truly vascularized tissue, they do have organs that are specialized for specific functions, analogous for example to the functions of leaves and stems in vascular land plants. Bryophytes depend on water for reproduction and survival.
