Organic

Second layer of soil

Topsoil

Third layer of soil

Subsoil

Has one cotyledon, grasses

Monocot


Is broad leaves, two cotyledon, drags whole seed out of the ground

Dicot

Regulated gas exchange for photosythesis

Stomata

Cells that transport water and minerals from the soil up through the plant

Glycine max

Cell divisions (mitosis) occur in the

Meristem

Total amount of dry matter produced at harvest

Dry matter

Process of inducing flowering by meeting a requirement of exposeure to cold temps. for a period of time

Venalization

Measures of heat accumulation to predict the growth

Growing degree days



((Tmax+Tmin)/2)-Tbase

5 Stages of Plant development

Germination


Emergence


Veg. Growth


Senesence


Reproduction

Process of breaking, scratching or mechanically altering the seed coat

Scarification

Cotyledons are above the ground (dicot)

Epigeal emergence

Cotyledons is below the ground, the radical leaves first (monocot)

Hypogeal emergence

Plant stops depositing energy in seed

Physiological maturity

Moisture content of seed is appropiate for processing and storage

Harvest maturity

Total water consumed in the production of plant biomass. Water loss through transporation by the plant plus water loss through evaporation

Evapotranspitation

Waxy layer in the roots that force absorbed soil solution to travel through cells rather than between

Casparian Strip

Symbiotic relationship between fungas and the roots of plants, improved nutrients and water uptake
