Random Glossaries Flashcards
organic compounds containing both an amino group (NH2) and a carboxylic acid group (COOP) that is linked together by peptide bonds to form proteins.
Amino acids
a type of cell plastid occurring in the green parts of plants, containing chlorophyll pigments and functioning in photosynthesis and protein synthesis.
Chloroplast
abnormal bending or cup formation of leaves caused by faster growth on one side of the leaf or by sudden shrinkage of the tissues on leaf margin.
Cupping
any of the numerous proteins or conjugated proteins produced by living organisms; it functions as a biochemical catalyst/substance that modifies and
increases the rate of reaction without being consumed, altered or destroyed in the process, e.g., the digestive enzyme called amylase, converts starch to sugar.
Enzyme
the yellowing or whitening of normally green tissues due to inadequate light.
Etiolation
a localized area of diseased or disordered tissue.
Lesion
death of a cell or group of cells as a result of injury, disease, or other pathologic state, usually resulting in color change of the affected tissue from green to brown.
Necrosis
a living organism capable of causing a disease(s).
Pathogens
refers to the synthesis of chemical compounds in the presence of light, especially the manufacture of organic compounds, primarily carbohydrates, from carbon dioxide and a hydrogen source (such as water), with simultaneous liberation of oxygen, by chlorophyll-containing plant cells.
Photosynthesis
the process (mechanical, physical or chemical) applied on seeds to weaken the seed coat and increase its permeability to water and gases.
Scarification
an injury to plants, which results in local death of plant tissues; in summer it is caused by excessive solar radiation; in winter it is caused by the great variation
of temperature on the side of the plant that is exposed to the sun.
Sunscald
a condition where the interveinal part of the leaf turns pale, chlorotic or translucent, while the veins remain normal green or dark green.
Vein banding/greening
