The period durning which an organism growth and activity decreases or stops is called?
The period when an organism growth and activity decreases is called dormancy. This is taught biology.
What Happens To a plant During Dormancy?
is a period when an organism growth or activity stops
What period during embryo is alive but not growing is called?
dormancy
A long period of inactivity where organisms survive unfavorable environmental conditions?
hibernation
What does dormant period mean?
Dormancy is another name for resting or sleeping. The plant goes into a self-induced, vegetative state - similar to suspended animation. This occurs in various plants and in various stages of plant growth. For example most seasonal bulbs have and over wintering stage, where they lie dormant so that they can survive cold weather and frost, the same applies to deciduous trees - they shed their leaves and go dormant during the winter. Dormancy is also found in seeds, where the seed can lay dormant for months or years (using little or no food reserves) until the conditions are right for germination. Dormancy is normally controlled by naturally occuring growth regulators within the plant (or cell).

How is germination promoted after a period of dormancy?
This depends on the type of seed. Providing the right conditions for the type of seed is vital. For instance most alpine seeds require a period below zero before they will germinate.
What ends dormancy of a seed?
Dormancy is poorly understood in terms of what causes it although it is likely that very many mechanisms exist, most of them probably chemical in nature. Some responsible compounds have been isolated, but in most cases, how they work is not understood. Breaking of dormancy is reasonably well understood in empirical terms. Things that are known to break dormancy include, particular cycles of wet and dry and/or heat and cold, exposure to one period above or below a certain temperature for a certain minimum period, exposure to certain chemicals (such as smoke), abrasion of the seed-coat (perhaps by being eaten but not digested). The list is considerable and particular seeds may require any one or more triggers to germinate.
Does the type of seed matter for germination?
Seeds from different plants have different requirements for germination. Some require more moisture or less moisture or will sprout in water, They may need different temperatures to germinate. Some seeds require a period of dormancy while something happens to the embryo internally. Some require a period of wetness to soften a hard outer shell or a period of cold or freezing weather before it will sprout.
What effects seed germination?
Following factors are to be taken in to consideration foe seed germination-: 1) Dormancy period -- A seed requires to undergo a period of dormancy after its formation. During this period the seed 'rests' and may refuse to germinate properly. This period varies from seed to seed . Seeds of water melon or red gourd do not have a dormany period and may germinate easily immediately after their formation in the fruit. Others require dormancy period ranging from a few weeks to a few months. 2) Viability of a seed -- It is exactly like expiry date/period of a commercial product. It must not be confused with the dormancy or 'resting period' After the resting period a seed bcomes ready to germinate.But this readiness is not for ever. It literally expires after cerain period.After that seed will not germinate. This 'ready to germinate' period is the viability period of a seed. It may vary from a few years to many centuries.Seeds of Lotus are reported to have germinated even after eight hundred years! In that case their viability period is atleast that much if not more. After considering the two inherent factors, let us now look in to the external factors. 3) Soil moisture or water -- This is required to trigger the mechanism of germination.In in absence of moisture the seeds can not germinate ; but when it is available it is imbibed by the seed coat and the enzymes in side become active and functional. The amount of water does not matter in the initial stages; But later on it becomes critical. 4) Soil Texture - Does not matter during germination. Seeds can even germinate with out soil on the piece of a moist blotting paper. 5)Soil pH--Should too acidic. pH 5 to 8 is alright. 6) Soil temparature - It should be on the warmer side.Lesser the temp. lesser the rate of germination. 7) Light - It does not affect the process of germination; but some seeds do germinate better in the ABSENCE of light. They like darkness for germination it seems.

How does a checking account get release from a dormant status?
Either to deposit or create activity within a bank stated period of time to pull it out of dormancy. Rules created within individual banking rules and regulations.
Venus fly trap dormancy?
Venue fly traps must have a dormancy period or they will die. The dormancy is usually three to five months and usually over the winter months.
