D) Active transport. Show Answer Correct Answer: B) Transpirational pull. 5. Why is water essential for the transport of nutrients in plants? A) It strengthens plant cell walls. B) It reduces the temperature of the plant. C) It dissolves nutrients for easy transport. D) It protects against pests. Show Answer Correct Answer: C) It dissolves nutrients for easy transport. 6. What type of blood do the arteries usually except for the Pulmonary artery carry? A) Oxygenated Blood. B) Deoxygenated Blood. C) All the above. D) None of the above. Show Answer Correct Answer: A) Oxygenated Blood. 7. Both the xylem and the phloem tissues can be found in the stem, roots and leaves of a plant. A) True. B) False. C) All the above. D) None of the above. Show Answer Correct Answer: A) True. 8. Suction in Transpiration A) It is caused by the pressure of water in the roots. B) It occurs when water evaporates from the leaves, creating a suction that pulls water up the stem. C) It is a process that only happens at night when the temperature is cooler. D) It is the result of soil moisture being absorbed by the roots. Show Answer Correct Answer: B) It occurs when water evaporates from the leaves, creating a suction that pulls water up the stem. 9. Why do root hairs cells have thin cell walls? A) So that the flow of water into root hair cells is fast. B) So that they can photosynthesise faster. C) So the cells can burst. D) None of the above. Show Answer Correct Answer: A) So that the flow of water into root hair cells is fast. 10. True or False:Xylem transports water and minerals in both upward and downward directions.
