1. Transport in Plants

2. Body is too large. Diffusion from the external environment is not an option Why do large organisms need a transport system?

4. Most plants have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem and phloem. Transport Systems

5. The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant. Xylem

6. Phloem, which is made up of living cells, carries the products of photosynthesis (organic nutrients) from the leaves to the other parts. Phloem

7. Absorption of Water

9. Transpiration Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants.

10. Stomata

11. Stomata

12. Transpirational pull is the main force behind the movement of water through the xylem. Transpirational Pull

13. Capillarity

14. Xylem in root Soil particles Leaves Root hair cells Xylem in stem Transpiration Use the following words to prepare a flow chart showing water transport in plants

15. Why organisms need a transport system Xylem Phloem Transpiration Transpirational pull Capillarity Stomata Guard Cells Osmosis What we learned

16. Difference between Dicot and Monocot

17. Dicot Root

21. Dicot Stem Xylem Phloem

22. Which of the following shows section of root? Root Stem

23. Monocot Stem

24. Leaf

26. Phloem

27. Viewing Xylem 13.1 Looking at root hairs 13.2 Demonstrate transpiration 13.3 Comparing water loss from each side of leaf 13.4 Stomata and water loss 13.5 Measuring the rate of water uptake 13.6 Experiments related to transport in plants

28. Osmosis Transpiration Diffusion What is the name of the process by which water travels up through a plant from the roots to the leaves?

29. Glucose Carbon dioxide Minerals What substances, necessary for growth, do plants take in along with water?

30. Diffusion Osmosis Active absorption Through which method does water enter plant cells?

31. They are similar to human hair They increase surface area They produce toxic products What is special about root hair cells?

32. Xylem vessels carry water from the leaves to the roots Xylem vessels carry water from the roots to the leaves Xylem vessels carry sugar from the roots to the leaves Which of the following statements is true of xylem?

33. Phloem tubes carry food from the leaves to the storage organs Phloem tubes carry nitrates from the leaves to the roots Phloem tubes carry food from the roots to the leaves Which of the following statements is true of phloem tubes?

34. Water travels up through plants, from the roots to the leaves, through their __________ vessels. It is pulled up the plant by two forces ________ and _________. The transpiration stream ends with water ________ from the leaves through the ________. (Phloem, Osmosis, Xylem, Evaporating, Suction pressure, stomata, Water, Capillarity)
