AP BIOLOGY

Detailed explanation-1: -Non-vascular plants such as liverworts and mosses move water and nutrients by osmosis and diffusion. Because non-vascular plants are small (typically one cell thick) they do not need conducting tissues and a complex system to move water; whereas vascular plants are large, and need a more complex system.

Detailed explanation-2: -Passive osmosis is used by nonvascular plants to transport materials to internal cells. Rhizoids are used to transport nutrients and minerals. Plants excrete waste through the use of their leaves. Diffusion is used to excrete waste through microscopic openings on their leaves.

Detailed explanation-3: -They lack roots, stems, and leaves. Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat.

Detailed explanation-4: -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.
