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 wall would burst due to the pressure of the environment The plant cell would become turgid from an influx of water. . Plasmolysis would occur. 2. The guard cells differ from other epidermal cells of the leaf in having: Lysosomes Mitochondria Chloroplasts Endoplasmic reticulum 3. Root hairs have a low volume to surface area ratio in order to obtain more water and minerals False True 4. The translocation of organic solutes in sieve tube members is supported by: Mass flow involving a carrier and ATP Cytoplasmic streaming P-proteins Root pressure and transpirational pull 5. Decreased ion absorption True False 6. Why are xylem cells dead? Lignin is impermeable Because they have no nucleus Just because 7. Supply the number of the part of the root which increases the total absorption surface of the root 6 2 1 4 8. The sodium-potassium pump requires energy to move sodium and potassium ions across the cell membrane. Which of these describes the process used by the sodium-potassium pump? Active transport Photosynthesis Diffusion Osmosis 9. Which of the following cell types is alive at maturity and provides sugars to a plant? Vessel elements sieve-tube elements/members tracheids Collenchyma cells 10. Which of these is not an advantage of transpiration? Cooling effect It enables a transpiration stream Aids translocation 11. The Xylem is ______ and the phloem is _______. In general, the xylem is ________ and the phloem is ________ Yellow, green, inward, outward Green, yellow, inward, outward Yellow, green, outward, inward Green, yellow, outward, inward 12. Which of the following is involved in the control of water movement into a plant? Apical meristem Epidermis Casparian strip cortex 13. The casparian strip at the endodermis blocks which pathway? Symplast Apoplast 14. In the cell wall what enables the apoplast pathway to function Oxygen Cytoplasm Water filled spaces Cellulose 15. Guard cells help in: Transpiration Fighting against infection Guttation Protection against grazing 16. The primary purpose of root hairs is to Increase absorption of water. Anchor the plant to the soil. Fight off infections. Increase absorption of sugars. 17. What is the function of a cambium? Create new xylem and phloem cells Create new phloem cells Separates the xylem and phloem only Create new xylem cells 18. Which of these is a mutualistic association of plant roots and fungi? Mycorrhizae Lichens Mushrooms Hyphae 19. Transpiration is: The movement of water up the xylem using osmosis The loss of water vapour from areal parts of the plant due to evaporation 20. Water moves throughout a plant through Xylem tissue. Phloem tissue. Cork cambium. Casparian strip 21. During transpiration, water moves through a plant and moves out into the atmosphere through the leaves. Transpiration is the result of the interaction of which two parts of a plant? Stomata and Vascular tissue Root and Vascular tissue Anthers and Roots Stomata and Stamen 22. Match the vascular bundle, Xylem with its transported substances Water, dissolved minerals Sugars, Metabollic products 23. The immune system produces cells (macrophages) that can fight disease, but these could not be transported around the body of an animal without interacting directly with the - Nervous system Circulatory system Integumentary system Respiratory system 24. Stomata of a plant open due to: Influx of Phosphorous ions Influx of Potassium ions Efflux of Phosphorous ions Efflux of Potassium ions 25. Root hair cells absorb mineral ions using Osmosis Active transport Diffusion 1 out of 25 Time is Up! Time's up
