AP BIOLOGY

Detailed explanation-1: -Also referred to as lower plants, non vascular plants are usually found inhabiting moist and damp areas, in water, bogs, swampy and shady regions, which lack specialized vascular tissues. Consequently, absence of xylem and phloem causes them to be primitive plants possessing primitive parts.

Detailed explanation-2: -Liverworts are distributed worldwide, though most commonly in the tropics. Thallose liverworts, which are branching and ribbonlike, grow commonly on moist soil or damp rocks, while leafy liverworts are found in similar habitats as well as on tree trunks in damp woods.

Detailed explanation-3: -Mosses, being nonvascular plants, don ‘t need roots to grow, so they can easily cover moist areas. Mosses commonly grow close together in clumps or mats in damp or shady locations.

Detailed explanation-4: -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.
