The study of Bryophytes (liverworts, hornworts and mosses) are called Bryology.  Bryology is a major subject of Botany. Bryophytes  are characteristically limited in size and prefer moist habitats although they can survive in drier environments. They are called amphibians of plant kingdom. The bryophytes consist of about 20,000 plant species. Today,I'm giving the most important questions of Bryology. I hope,this post will be helpful both for BSc(honours)  and Degree students.
