Plant Physiology

1. Transports sugar from shoot to root.
4. Polymer made of glucose monomers (part of the cell wall).
5. A vacuole membrane with very high osmotic pressure.
7. Organisms that make all of their own food from ions and simple molecules.
9. Monosaccharide composed of 6 carbons.
11. Passive transport that allows the movement of molecules such as K+ in response to an electrochemical gradient.
12. In an aqueous solution, ______________ form ring structures.
16. A cell in a hypertonic solution will become _____________.
18. _______ are light particles.
19. Organic compounds with the empirical formula Cm(H2O)n
20. Has a backbone made of galacturonic acid and rhamnose.
21. A turgid cell results from a _________ solution.
22. pressure The pressure of the cell contents against the cell wall. (2 words)
23. Channels between cells that allow molecules movement.
25. Photons are absorbed by chlorophyll and energy is channeled towards the _________ of the light-harvesting complex. (2 words)
27. Electron carrier in the photosynthetic electron transport chain (also important in nitrogen assimilation).
28. An enzyme involved in the first major step of carbon fixation.
29. A protein that catalyzes a chemical reaction.

2. When H2O moves from a region of low concentration of solute to a reagion of high concentration of solute (passively).
3. Transports water, minerals, and nutrients from root to shoot.
4. Absorb blue and green light and transmit yellow, orange, and red light.
6. H2O can diffuse through a channel in the plasma membrane created by an _______ protein.
8. The heads of the phospholipid bilayer are _________.
9. Organisms that derive their food from other organisms.
10. A metabolic process that converts CO2 into sugars using the energy from sunlight.
13. Movement of molecules through the plasmodesmata is termed ____________ (2 words)
14. A hydrophobic barrier made of fatty acids that prevents cell organs from fusing.
15. Macromolecules composed of repeating structural units.
16. pump Creates an electrochemical gradiant across a membrane.
17. The chemical reasctions that happen in living organisms to maintain life.
24. Comprised of three aromatic alcohol monomers.
26. Proteins that help call wall expand by modifying interactions between cellulose and hemicellulose.
