Plant physiology

1. 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
3. collenchyma cells that have intercellular space and thickening proximal to the intercellular space
5. the process by which a solid holds molecules of a gas or liquid or solute as a thin film.
6. type of absorption that requires expenditure of metabolic energy
10. 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
11. biochemistry of plants
13. is the condition of the cell which causes the shrinkage of protoplast, when the cell is placed in the hypertonic solution
14. is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent).
15. first step in practically all metabolic reactions involving sugars and is an essential feature of transformation of CH2O

2. is the pressure exerted by the cell wall outwardly by expanding the protoplast.
4. Hunger considered as an invisible deficiency symptom exhibited by plants that have inadequate supply of essential elements but do not show any visual clues
7. visual deficiency symptoms not limited to one area of a plant but is rather present and spread all over the entire plant
8. disaccharide that results from partial degradation of cellulose
9. enzyme responsible for fixing carbon
12. Type of diffusion occurring between liquid substances cousin a recognizable change in the volume of the latter.
