Plant Physiology

3. common and limit the growth of plants
5. movement of atoms or molecules from an area of high concentration to an area of low concentration
9. promote cell division and delay aging of leaf by breaking down chlorophyll
11. process whereby the water from the cytoplasm of cells is removed causing the cytoplasm to shrink
12. contains a gram molecular weight of a substance dissolved in 1 liter of water
14. alive at maturity and have thickened cellulosic cell walls; elongated; rich in pectins
17. a chemical process in which a substance loses electrons
18. most abundant in middle lamella in the form of Ca or Mg salts of pectic acids
19. are chemical reactions in which energy is stored in molecules

1. the sum total of all the chemical reactions occurring in a cell or organism
2. resumption of growth by the embryo and its development to an independent seedling
4. the rates of diffusion of gases are inversely proportional to the square roots of their densities (as density is increased, rate of diffusion is decreased)
6. the chief component of the cell wall
7. least complex; simplest CH2O; building units of more complex CH2O such as oligo and polysaccharides
8. small particles suspended in water with sometimes glue-like consistency smaller than “suspension” particles and larger than true solute particles
10. the effect of light scattering on particles in colloid systems, such as suspensions or emulsions
13. a protein composite that appears in food processed from wheat and related species, including barley and rye
15. produced by dissolving a gram molecular weight of a water-solute substance in enough water to make a liter of solution
16. a special type of diffusion which is actually the movement of water through a differentially permeable membrane from an area of high concentration to an area of low concentration
18. the main component of living protoplasm
