Definition: Dormancy is a state of temporary metabolic inactivity or minimal activity. Plants generally go dormant in response to adverse growing conditions.
Many of these plants have a specialized metabolic process typically seen in cacti, known as Crassulacean acid metabolism, or CAM, which minimizes their need for water. Typically these orchids also exhibit one of two foliage forms.
Hummingbirds are the gluttons of the bird world, as their metabolic needs require them to consume twice their weight in food each day! As they move among flowers, they move pollen from one plant to the next.
These values were based on the ratio of the associated metabolic rate for the specific activity divided by the resting metabolic rate.
As the days cool and grasses go dormant, we often need to be reminded that certain metabolic activities continue in the roots when the soil is 40 degrees F or higher - and they need that water to function.
There is a sort of metabolic intellect down there in the fabric of life, an intellect which, among other things, has evolved over the eons to negotiate the complexities of energy economics, the getting, ...
Catabolic pathway - A type of metabolic pathway whereby large, complex molecules are broken down into smaller ones in order to release energy.
Catkin
Cell cycle - The complete sequence of events of a dividing cell.
Most seeds are fairly dry and need to rehydrate to get the metabolic processes going. For fat seeds in tough hulls (morning glories, squash), I often soak them on a plate of water overnight before planting. Plate not bowl! ...
Dormant - A state of rest and reduced metabolic activity in which plant tissues remain alive but do not grow.
Oils also kill insect eggs by penetrating the shells and interfering with metabolic and respiratory processes. In addition, oils disrupt feeding by insects such as flea beetles, whiteflies, and aphids without necessarily killing them.
Potassium improves overall vigor of the plant. It helps the plants make carbohydrates and provides disease resistance. It also helps regulate metabolic activities.
There are three additional nutrients that plants need, but in a smaller amounts: ...
senescence. The stage of growth in a plant or plant part from maturity to death, characterized by an accumulation of metabolic products, an increased respiratory rate, and a loss in dry weight.
Now is the time to start adding suet to your bird feeding ritual. Insect feeders will flock around to gobble down this tasty treat that is high in protein and fat. Don't distress about chubby birds. Birds have high metabolic rates and burn their fat ...
Terpenoids in basil are important anti-cancer hytochemicals-naturally occurring substances that work in conjunction with vitamins and other food nutrients to stimulate protective enzymes and block metabolic pathways associated with the development ...
