AP BIOLOGY

Detailed explanation-1: -Vascular plants have xylem and phloem that transport water and nutrients to the rest of the plant. Nonvascular plants absorb nutrients and water directly into their cells.

Detailed explanation-2: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-3: -They grow on rocks, sand dunes, glaciers, mountains, etc., and look like green carpets. Are algae vascular or nonvascular? Algae are photosynthetic nonvascular plants as they lack roots, stems, and leaves. Not all algae are considered nonvascular, but only those belonging to the Viridiplantae clade.

Detailed explanation-4: -Nonvascular Plants. 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).
