DENDROLOGY

Detailed explanation-1: -A few algae, liverworts, hornworts and mosses are nonvascular plants. Reproduction in such plants is through spore production in contrast to seeds, as a result they do not bear wood, flowers or fruits.

Detailed explanation-2: -How do nonvascular plants and seedless vascular plants reproduce? Nonvascular plants and seedless vascular plants both reproduce by sexual means in which there is the production of male and female gametes, and asexual means in which there is a production of spores by the sporophytes.

Detailed explanation-3: -Mosses, hornworts, and liverworts are nonvascular plants called Bryophytes. There are an estimated 17, 000 species of bryophytes and occupy almost every habitat type.
