Why are xylem cells dead? Lignin is impermeable Just because Because they have no nucleus2. Root hairs have a low volume to surface area ratio in order to obtain more water and minerals False True3. Root hair cells absorb mineral ions using Osmosis Active transport Diffusion4. _____ is a part of the medulla that occur in-between the vascular bundles of the dicotyledonous stem Phloem Cambium Xylem5. Guard cells help in: Protection against grazing Guttation Transpiration Fighting against infection6. What is the role of the fibres? Transport water Support vessels Packing tissue7. Which of these is a mutualistic association of plant roots and fungi? Mushrooms Hyphae Mycorrhizae Lichens8. Which is made of dead cells? Phloem Xylem9. Which of the following mammalian body systems work together to regulate internal body temperature? Muscular and skeletal Circulatory and integumentary Endocrine and lymphatic Excretory and immune10. Sugar movement through a plant is best described as going from a _____________ to a ______________. Source; sink Isotonic environment; hypertonic environment Hypotonic environment; isotonic environment Sink; source11. Active transport of minerals creates a water potential gradient into the flower leaves roots stems12. What are the cells called that surround the stomata? Guard Cell Red blood cell white blood cell13. Stem cells None of the above Non-differentiated cells Somatic cells All of the above14. Which of these is not an adaption of parenchyma? Isodimetric No cholorplast Elongated cells15. The movement of oxygen into a cell until equilibrium is reached without the use of ATP is an example of: Active transport Passive transport Osmosis Oxidative transport16. Which of these is a mutualistic association of plant roots and fungi? Mycorrhizae Mushrooms Lichens Hyphae17. Which is the most commonly used pathway for water Symplast pathway Vacuolar pathway Apoplast pathway18. The plant cells that most directly affect the rate of transpiration are Guard cells. Sclerenchyma cells. Sieve tube members. Parenchyma cells.19. 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 - Circulatory system Integumentary system Nervous system Respiratory system20. Which of the following cells types is dead at functional maturity? Sieve-tube elements Guard cells Vessel elements Collenchyma cells21. In the cell wall what enables the apoplast pathway to function Cytoplasm Cellulose Water filled spaces Oxygen22. Water will move from a ____ concentrated region to a _____ concentrated region.  It's like a magnet pulling water up the plant's plumbing system High, low Low, high23. The following makes up a vascular bundle except? Cambium Phloem Xylem Chloroplast24. Which of the following would result from placing a plant cell in a hypertonic environment? The plant cell would become turgid from an influx of water. The plant cell wall would burst due to the pressure of the environment Plasmolysis would occur. There would be no net movement of water into or out of the plant cell.25. Root hair cells take in water molecules from the air. False True26 out of 25Time is Up!
