Question

Define dormancy and breaking down dormancy ? Give example of each.

Answer 1

Answer:

Your answer is.............

Explanation:

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. ... Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in areas with an unpredictable climate.Example - African Lungfish: Lungfish experience a period of dormancy in response to drought.

The seeds of many species do not germinate immediately after exposure to conditions generally favourable for plant growth but require a “breaking” of dormancy, which may be associated with change in the seed coats or with the state of the embryo itself. Example-Light. Exposure to light breaks down the germination inhibitors in some types of seeds, particularly wildflowers that produce small seeds. Press seeds that need light exposure onto the surface of moist potting medium or garden soil, but don't cover them with soil.

Answer 2

☆Dormancy: The state of having normal physical functions suspended or slowed down for a period of time.

Examples: African Lungfish: experience a period of dormancy in response to drought.

☆Breaking down dormancy: The seeds of many species do not germinate immediately after exposure to conditions generally favourable for plant growth but require a "breaking of dormancy", which may be associated which change in the seed coat or with the state of the embryo itself.
