Terms | Definitions |
|---|---|
 Photosynthesis | Red and blue wavelengths of light are transformed by plant tissue into chemical energy. |
| Plant | an organism that is green and photosynthetic |
| Cellulose | a complex carbohydrate occurring in the walls of the majority of plants; it is composed of hundreds of simple sugar molecules, glucose, linked together in a characteristic manner; cotton fibers are largely cellulose |
| Spores | a one-celled or a few-celled reproductive unit that develops into a multi-cellular organism without first fusing with another reproductive unit; contrast with seed and gamete |
| Botany | the study of plants and plantlike organisms (plant biology) |
| ecologic services | products of ecosystems that sustain aquatic and terrestrial life, including the production of oxygen (through photosynthesis) the filtering of pollutant, and the stabilization of soil |
| Wood Age | the span of history during which wood was the, or one of the, principal materials for houses, fuel, and vehicles |
| Hypothesis | a tentative theory or supposition provisionally adopted to explaining certain facts and to guide in the investigation of other facts. |
| scientific method | a repeated process of stating testing, and refining hypotheses that best explain a natural phenomena (tests and interpretation of an hypothesis). |
| technology | is the application of information to industrial or commercial objectives. It does not require an understanding of how or why a given process functions |
| Plant genetics | the study of plant heredity |
| plant ecology | is the study of how the environment affects plant organisms |
| plant systematics | knowledge of genetics is a prerequisite for the study of plant evolution and classification |
| paleoecology | a field of ecology that reconstructs past vegetation and climate from fossil evidence |
| biogeography | the study of the geographic distribution of organisms and the reasons for the limits to their distribution, often include over geologic time and with a focus on taxonomically related organisms (families, genera) |
| Metabolism | the process by which plants perform photosynthesis, transport materials internally, construct unique molecules, and use hormones to affect their behaviour |
| plant physiology | study of metabolism also called plant molecular biology |
| plant morphology | the study of how a plant develops from a single cell into diverse tissues and organs and an array of outer surfaces and shapes |
| plant anatomy | the study of a plant's internal structure, its tissues and cell types. |
