Which of these is not an adaption of parenchyma? Isodimetric No cholorplast Elongated cells 3. The guard cells differ from other epidermal cells of the leaf in having: Lysosomes Mitochondria Endoplasmic reticulum Chloroplasts 4. Why are xylem cells dead? Lignin is impermeable Just because Because they have no nucleus 5. The plant cells that most directly affect the rate of transpiration are Sclerenchyma cells. Sieve tube members. Guard cells. Parenchyma cells. 6. Which of the following is involved in the control of water movement into a plant? Epidermis Casparian strip cortex Apical meristem 7. Hormones released during puberty lead to increased height in humans. What two systems interact to cause this increase in height? Integumentary and nervous Digestive and muscular Circulatory and reproductive Endocrine and skeletal 8. The primary purpose of root hairs is to Increase absorption of water. Increase absorption of sugars. Anchor the plant to the soil. Fight off infections. 9. Cohesion tension theory operates in _______. Both 1 and 2 None of these Active absorption Passive absorption 10. The Xylem is ______ and the phloem is _______. In general, the xylem is ________ and the phloem is ________ Green, yellow, outward, inward Green, yellow, inward, outward Yellow, green, inward, outward Yellow, green, outward, inward 11. If the plant cell is immersed in water, the water continues to enter the cell until the _____ Cell bursts Diffusion pressure deficit is the same inside the cell as outside Concentration of water is the same inside the cell as outside Concentration of salts is the same inside the cell as outside 12. Which of the following best describes the function of the vascular tissues in plants? Converts the atmospheric carbon dioxide into oxygen. Produces sugar in the presence of sunlight. Controls when trees lose their leaves Helps transport substances throughout the plant. 13. Water moves throughout a plant through Casparian strip. Phloem tissue. Cork cambium. Xylem tissue. 14. How does phloem transport sugars? Transpiration Translocation 15. The main force causing water to flow from the roots to the leaves is Root pressure Transpiration Capillaries Respiration 16. Which factor affects transpiration? All of the above Wind velocity Temperature Humidity 17. The following makes up a vascular bundle except? Xylem Cambium Phloem Chloroplast 18. Which of the following cells types is dead at functional maturity? Collenchyma cells Guard cells Vessel elements Sieve-tube elements 19. Xylem is the plant structure that provides which of the following functions? Automatic response to changes in its environment Production of gametes necessary for reproduction Transport of sugar from the leaves to the roots Transport of water and minerals from roots to the stem 20. Match the vascular bundle, Xylem with its transported substances Sugars, Metabollic products Water, dissolved minerals 21. The translocation of organic solutes in sieve tube members is supported by: Root pressure and transpirational pull P-proteins Mass flow involving a carrier and ATP Cytoplasmic streaming 22. What are the cells called that surround the stomata? white blood cell Guard Cell Red blood cell 23. Which is made of dead cells? Xylem Phloem 24. Water and minerals move through the xylem from the roots to the top of the plant by Osmosis Pressure Diffusion Equilibrium 25. Stomata open and close in response to Stimulation by auxins producing rapid growth. Water being pumped in and out of guard cells. Crystal formation in the plant due to excess glucose The lack of available sunlight during the night. 1 out of 25 Time is Up! Time's up
