Water will move from a ____ concentrated region to a _____ concentrated region. It's like a magnet pulling water up the plant's plumbing systemLow, highHigh, low2. What do you use to measure transpiration? Measuring tapeBongRulerPotometer3. Which factor affects transpiration?TemperatureHumidityAll of the aboveWind velocity4. Stem cells Somatic cellsNone of the aboveAll of the aboveNon-differentiated cells5. The process in which plants lose water vapor from the stomata is known asTransmitationTransmutationTranslocationTranspiration6. Which of these is not a reason why plants need a transport system? Small surface area to volume ratioToo activeMulticellularThey can't rely on diffusion alone7. Which of these is not an adaption of parenchyma? No cholorplastElongated cellsIsodimetric8. How does phloem transport sugars? TranslocationTranspiration9. Cohesion tension theory operates in _______. Both 1 and 2Passive absorptionActive absorptionNone of these10. The casperian strip contains what making it waterproof? FibresSuberinWaxy cutile11. Water moves throughout a plant through Cork cambium.Phloem tissue.Xylem tissue.Casparian strip12. _____ is a plant tissue that transport food from the leaves to the stem and rootGuard CellsPhloemXylem13. Xylem is the plant structure that provides which of the following functions?Transport of sugar from the leaves to the rootsAutomatic response to changes in its environmentTransport of water and minerals from roots to the stemProduction of gametes necessary for reproduction14. The following makes up a vascular bundle except?CambiumXylemPhloemChloroplast15. In the cell wall what enables the apoplast pathway to function CytoplasmCelluloseOxygenWater filled spaces16. Which of the following cells types is dead at functional maturity? Guard cellsCollenchyma cellsVessel elementsSieve-tube elements17. What is the role of the fibres? Packing tissueTransport waterSupport vessels18. The phytochrome system controls photoperiodicity in plants. The diagram describes the following exceptIn the morning plants will have more PrDuring the night Pfr is converted to Pr.In the morning plants will have more Pfr19. Stomata open and close in response to Water being pumped in and out of guard cells.Crystal formation in the plant due to excess glucoseThe lack of available sunlight during the night.Stimulation by auxins producing rapid growth.20. The translocation of organic solutes in sieve tube members is supported by:Cytoplasmic streamingRoot pressure and transpirational pullMass flow involving a carrier and ATPP-proteins21. Stomata of a plant open due to:Influx of Potassium ionsEfflux of Potassium ionsInflux of Phosphorous ionsEfflux of Phosphorous ions22. Which of the following would result from placing a plant cell in a hypertonic environment? There would be no net movement of water into or out of the plant cell.The plant cell would become turgid from an influx of water. .Plasmolysis would occur.The plant cell wall would burst due to the pressure of the environment23. Which of the following would result from placing a plant cell in a hypertonic environment?Plasmolysis would occur.There would be no net movement of water into or out of the plant cell.The plant cell wall would burst due to the pressure of the environmentThe plant cell would become turgid from an influx of water.24. Supply the number of the part of the root which increases the total absorption surface of the root612425. The plant cells that most directly affect the rate of transpiration are Guard cells.Parenchyma cells.Sieve tube members.Sclerenchyma cells.26 out of 25Time is Up!
