Plant Physiology

3. collenchyma cells that have intercellular space and thickening proximal to the intercellular space.
6. enzyme responsible for fixing carbon.
7. the process by which a solid holds molecules of a gas or liquid or solute as a thin film.
8. disaccharide that results from partial degradation of cellulose.
9. composed of repeating units of amino acids linked together by a peptide bond.
11. the pressure exerted by the cell wall outwardly by expanding the protoplast.
14. first step in practically all metabolic reactions involving sugars and is an essential feature of transformation of CH2O.
15. type of diffusion occurring between liquid substances cousin a recognizable change in the volume of the latter.
16. many enzymes belong to this group, e.g. respiratory enzymes.
19. the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent).
20. type of absorption that requires expenditure of metabolic energy.

1. process whereby genetic info in mRNA directs the order of insertion of the specific amino acids during protein synthesis.
2. a thick band of cell wall present on the radial and transverse walls of the endodermal cells of the root mostly composed of a lipophilic biopolymer, that acts as a protective barrier against excessive water loss, called suberin.
4. biochemistry of plants.
5. considered as an invisible deficiency symptom exhibited by plants that have inadequate supply of essential elements but do not show any visual clues.
10. the condition of the cell which causes the shrinkage of protoplast, when the cell is placed in the hypertonic solution
12. can cause denaturation of enzymes.
13. plants that are deficient of this nutrient exhibit light yellow chlorosis and necrotic spotting on the leaves and failure to expand of the leaf blades.
17. process whereby genetic info in DNA is employed to order a complementary sequence of bases in a new RNA chain.
18. visual deficiency symptoms not limited to one area of a plant but is rather present and spread all over the entire plant.
