Nonvascular Plants Defined Nonvascular plants belong to the division Bryophyta, which includes mosses, liverworts, and  hornworts. These plants have no vascular tissue, so the plants cannot retain water or deliver it to  other parts of the plant body. The bryophytes do not possess true roots, stems, or leaves, although  the plant body is differentiated into leaflike and stemlike parts. In some species, there are rootlike  structures called rhizoids. With no vascular tissue, the bryophytes cannot retain water for long  periods of time. Consequently, water must be absorbed directly from the surrounding air or another  nearby source. This explains the presence of mosses in moist areas, such as swamps and bogs,  and on the shaded sides of trees. The life cycle of the moss is typical of the bryophytes. Flask-shaped archegonia, located among the  top leaves of the female gametophytes, produce one egg cell each. Antheridia, located similarly on

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
