DENDROLOGY

Detailed explanation-1: -Nonvascular means there is no vascular system. In nonvascular plants, there is no vascular system, or xylem and phloem, to transport water and nutrients. Nonvascular plants absorb nutrients through their cells.

Detailed explanation-2: -Nonvascular plants are plants that do not have any special internal pipelines or channels to carry water and nutrients. Instead, nonvascular plants absorb water and minerals directly through their leaflike scales. Nonvascular plants are usually found growing close to the ground in damp, moist places.

Detailed explanation-3: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
