2. Plants –except for bryophytes which have no true stems, leaves, or roots--have 2 body sections: Shoot systems, root systemsGrowth in length grows by division of stem cells in regions called apical meristems.Note cells of plants are rarely more than 50 µm in diameter, while many unicellular protists were up to 100 or 200 µm at the largest point.

16. 13 A botanist discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, the following characteristics are noted: flagellated sperm, xylem with tracheids, separate gametophyte and sporophyte phases, and no seeds. This plant is probably most closely related to * • mosses. • Chara. • ferns. • liverworts. • flowering plants.

22. 16 Like Van Helmont, you are conducting an experiment on plant growth. You take a plant fresh from the soil and it weighs 5 kg.

24. This figure shows the results of a study to determine the effect of soil air spaces on plant growth. Use these data to answer the following question.

25. The best explanation for the shape of this growth response curve is that • the plant requires air in the soil for photosynthesis. • the roots are able to absorb more nitrogen (N2) in high levels of air. • most of the decrease in weight at low air levels is due to transpiration from the leaves. • increased soil air produces more root mass in the soil but does not affect the top stems and leaves. • the roots require oxygen for respiration and growth.
