Question

iar cells are 7. What physical phenomenon or phenomena cause(s) ions and root-hair-cells-are-se molecules to enter the roots rather than remain in the soil? (0.5pt) tubular_figl_259268 8. How does the shape or morphology of root hairs facilitate the entry of water and nutrients'? (consider comparing it to the root) (1.5pt) 9. If a plant was able to actively vary the concentrations of solutes (ions & molecules) within its tissues, how should the plant distribute solutes to maximize water 'absorption into the root system (from the soil)? (2pts) 10. Draw from your lecture knowledge, and your experience in past biology courses, gardening, and beyond. What other items (chemical compounds/organisms) in the soil would the plant want to exclude from entering the roots? Give at least 3 (1.5pts) Essential Eleme Macronutrients Carbon (C) Hydrogen (HD) Oxygen (0) Nitrogen (N) Phosphorus (P) c Potism (K) Calcium (Ca) CH
