Welcome to your Transport in Plants(Senior Class Biology Study by Topics) NAME EMAIL PHONE NUMBER 1. Supply the number of the part of the root which increases the total absorption surface of the root 2 6 4 1 2. Rate of water absorption can be increased through ______. Increased photosynthesis Increased transpiration Decreased transpiration Decreased ion absorption 3. 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? Osmosis Active transport Photosynthesis Diffusion 4. Match the vascular bundle, xylem with its destination From root upwards From leaves downwards 5. Which of these is not a reason why plants need a transport system? They can't rely on diffusion alone Small surface area to volume ratio Multicellular Too active 6. Cohesion means... Water molecules tend to stick to the inside of the xylem vessel Water molecules tend to attract to each other, sticking together Water molecules tend to slide down the xylem vessel 7. Which of these is not an adaption of parenchyma? Elongated cells Isodimetric No cholorplast 8. Sugar movement through a plant is best described as going from a _____________ to a ______________. Hypotonic environment; isotonic environment Source; sink Isotonic environment; hypertonic environment Sink; source 9. The plant cells that most directly affect the rate of transpiration are Parenchyma cells. Sieve tube members. Sclerenchyma cells. Guard cells 10. The casperian strip contains what making it waterproof? Waxy cutile Fibres Suberin 11. Why are xylem cells dead? Lignin is impermeable Just because Because they have no nucleus 12. Which of these is a mutualistic association of plant roots and fungi? Mushrooms Mycorrhizae Hyphae Lichens 13. The translocation of organic solutes in sieve tube members is supported by: Cytoplasmic streaming Root pressure and transpirational pull P-proteins Mass flow involving a carrier and ATP 14. Water moves throughout a plant through Cork cambium. Xylem tissue. Casparian strip Phloem tissue. 15. The primary purpose of root hairs is to Increase absorption of sugars. Anchor the plant to the soil. Increase absorption of water. Fight off infections. 16. Which of the following cell types is alive at maturity and provides sugars to a plant? Vessel elements Collenchyma cells tracheids sieve-tube elements/members 17. Stem cells Non-differentiated cells Somatic cells All of the above None of the above 18. Guard cells help in: Transpiration Guttation Fighting against infection Protection against grazing 19. When beet root cylinders are washed and placed in cold water, anthocyanin does not come out. This indicates that most likely plasma membrane is: Impermeable to anthocyanin Permeable to anthocyanin Dead structure Differentially permeable to anthocyanin 20. Which of the following cells types is dead at functional maturity? Collenchyma cells Guard cells Sieve-tube elements Vessel elements 21.
