Question

Suggest a reason why the same number of seeds germinated in the drawer
as on the top of the desk.​

Answer 1

Explanation:

A2A A seed that can germinate in the dark has an advantage over those that would require direct light to germinate. If they absolutely needed to be close to or on top of the soil surface to germinate, they would be exposed to air and predators, so the seed or sprout might be eaten before it has a chance to grow, or the sprout might quickly dry out after germination from exposure to the air. A seed that can germinate in the dark can do so deeper in the soil, and have more protection from drying out or being eaten than one that sprouts on the surface. Not all seeds have the same requirements for either darkness or light, and many can germinate in either, but in general (barring other specific requirements such as vernalisation, fire, or digestion of the seed coat) germination tends to happen more in response to available water than either darkness or light.

Answer 2

It is most effective whilst the seeds in everlasting darkness that the darkish shape of phytochrome is energetic for lengthy sufficient to cause germination glaringly this prevents such seed germinating till they're buried.

Explanation:

• A seed that could germinate withinside the darkish has a bonus over the ones that could require direct mild to germinate.
• If they truly had to be near or on the pinnacle of the soil floor to germinate, they might be uncovered to air and predators.
• So the seed or sprout is probably eaten earlier than it has a risk to grow, or the sprout would possibly speedy dry out after germination from publicity to the air.
• A seed that could germinate withinside the darkish can accomplish that deeper withinside the soil, and feature extra safety from drying out or being eaten than one which sprouts on the floor.
• Not all seeds have the equal necessities for both dark and mild, and plenty can germinate in both.
• But in general, (barring different precise necessities consisting of vernalization, fire, or digestion of the seed coat) germination tends to appear extra in reaction to be had water than both darkness or light.
