tell me about abscission & dormancy?
Abscission :--- Abscission (from the Latin ab meaning away and scindere meaning to cut) is a term used in several areas of biology. In plant sciences it most commonly refers to the process by which a plant drops one or more of its parts, such as a leaf, fruit, flower or seed. In zoology the term may be used to describe the intentional shedding of a body part, such as the shedding of a claw husk, or the autotomy of a tail to evade a predator. In mycology it may refer to the liberation of a fungal spore. In cell biology abscission refers to the separation of two daughter cells at the completion of cytokinesis....!!
Dormancy:-- Dormancy is a period in an organism'slife cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are therefore able to make greater use of available resources......!!
Hopes dis will help u...!! :)))))
