The enzymes in the dry seeds get activated after absorbing water and it unlocks several chemical reaction leading to the germination of seed.
If the amount of water is to great around the bean seed it will die and not be able to germinate.
yes
The independent variable in an experiment could be factors such as light, temperature, or water levels. By manipulating the independent variable, such as changing the amount of light or water given to the radish seeds, you can observe how it affects their germination rate. Each independent variable can have a different effect on radish germination.
THe sugar dries out the roots and suffocates the plant becaus it can't take in water
High concentrations of chlorine in water can hinder seed germination by causing damage to the seed coat or inhibiting crucial enzyme activity necessary for germination. Lower concentrations may have little to no effect on germination rates. It is important to use water with safe chlorine levels for watering seeds to ensure optimal germination.
Like all other plants, the growth or germination of a seed is affected by the food supply by how abundant or how scarce it happens to be. A seed which needs special requirements may be very senstive to the amount of available food.
An example of an environmental cue for germination is the presence of water. When a seed absorbs water, it triggers biochemical processes within the seed that lead to germination. This cue initiates the growth of the embryo within the seed and the development of a new plant.
it affects it on its amount of water
The amount of rainfall affects the flow of the streams within the watershed area, and ultimately how much water is stored in the watershed.
electrolites in the water inhibit the plants ability to absorb water which is essencial for germination
