Bryophytes are usually small, lack tissue, and live in environments. b. Materials move in bryophytes by diffusion or from cell to cell. c. Bryophytes do not have roots, stems, or . d. Bryophytes have rootlike structures called , which anchor it to a surface. e. Reproduction in bryophytes requires water and occurs by . f. Mosses, liverworts, and are bryophytes. 2. The most common bryophytes, live in shady, damp environments and can survive long periods of . a. Mosses have leaflike structures that grow on a stemlike structure called a(n) . b. Mosses have rhizoids. c. Mosses are often the plants to grow in barren areas or after a natural disturbance such as a fire or a mudslide. d. Mosses can retain large amounts of , which makes moss a useful additive for potting soil. 3. look like the flattened lobes of a liver. a. The of liverworts are unicellular. b.

Each photosynthetic cell in a hornwort has only one Plant Diversity 29 Name Date Class Lesson Outline continued B. Vascular Seedless Plants 1. Vascular plants make up more than percent of plant species. 2. Unlike nonvascular plants, vascular plants contain vascular tissue in their , roots, and leaves. 3. plants contain tubelike structures that transport water and nutrients, which allows these plants to grow than nonvascular plants. 4. fuels come from the remains of ancient vascular seedless plants. 5. The , or leaves of ferns, make up most of a fern. a. Ferns grow in many , including dry, rocky cliffs and damp, swampy areas. b. People grow ferns in their homes and gardens and sometimes eat their young fronds, called . 6. Unlike mosses, have roots, stems, and leaves. a. Club mosses are small plants, whose stems grow along the and whose leaves are . b. The fine powdery spores of club mosses are been used to make 7. and have . have small leaves that grow in circles around the stems. a. Horsetail stems are hollow and the tissue contains ,a mineral found in sand, that makes them abrasive. b. Horsetails were once used to scrub .
