what does germination mean and what 3 conditions r needred for seed germination?

Answer 1

Germination is the resumption of growth of the embryo plant inside the seed.
Conditions
1. Temperature.

2. Water

Water is always needed to allow vigorous metabolism to begin. It is also sometimes needed to leach away a germination inhibitor within the seed. This is especially common among desert annuals. The inhibitor is often abscisic acid (ABA).

3 .Oxygen
a preceding period of dormancy (often).
The seeds of many temperate-climate angiosperms will germinate only after a prolonged period of cold. An inhibitor within the seed (probably abscisic acid - ABA) is gradually broken down at low temperatures until finally there is not enough to prevent germination when other conditions become favorable. This mechanism is of obvious survival value in preventing seeds from germinating during an unseasonably warm spell in the autumn.

Answer 2

germination is when growth begins after a periods of dormancy.

3 conditions needed are:
a. Water must be present to hydrate the protoplasm and allow metabolism
b. Warmth foe enzyme to work
c. Oxygen for respiration

Also there may be some seeds that needs light but many do not. First the seeds need to respire, and use the food stored in the cotyledons. Before this store has run out they start to photosynthesize.

Answer 3

Germination is when the water enters the seed and allows germination to take place
you need gravity, water and a moderate temperature and evetually light

Answer 4

Germination means that the seed opens and sprouts a tail root that needs to be able to secure itself in a fertail soil. It needs heat and water in addition to the earth. Some seeds actually need some cold to do their best, this is why some plants due better in the colder areas of our country than others and vice versa.

Answer 5

germination is when a seed sprouts and seed needs water, light, and oxygen to germinate.... (although u can say these three are needed, but i always thought u need water for seed germination)

Answer 6

it means growing of seeds into a new plant.is requires three main conditions they are sunlight,water and carbon dioxide
