Scientists know the mechanism behind the phenomenon: In cool air and darkness, the bottom-most petals of certain flowers grow at a faster rate than the upper-most petals, forcing the flowers shut.
How does light intensity affect the distribution of dandelions?
Light intensity will affect the abundance of dandelions. > Dandelions will adapt to capture more sunlight. > Soil pH will affect the abundance of dandelions, if to acidic, will destroy plant. > Wind will help the reproduction of the dandelions, hence there should be more dandelion present. >
How long does it take for a dandelion to open?

What variables should be considered when measuring light intensity?
Abiotic measurement equipment
- Abiotic factors can all be measured to show the living conditions in an ecosystem.
- Light meters can be used to measure light intensity.
- Errors can be made when measuring light intensity by accidentally shading the light meter.
- Soil moisture and soil pH meters are also available.
How does light intensity affect plant distribution?
Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. Some plants adapt to low light, usually by developing bigger leaves to optimse photosynthesis. This inhibits new plant growth.
What do you call a dandelion when it turns white?
A yard full of golden dandelions in bloom can be a gorgeous sight. Eventually, all those beautiful flowers eventually turn to white globes of exposed seeds that are often called “puffballs.”
What are the stages of a dandelion?

Can you grow dandelions indoors under grow lights?
Growing the plants indoors gives you more control over their soil, light conditions and spread. Grow lights are essential if you want to grow dandelions indoors. Dandelions are hardy in U.S. Department of Agriculture plant hardiness zones 3 through 9. Dandelions grow best with a full day of sunlight.
Why are dandelion seeds not long lived in the soil?
Longevity: Dandelion seeds are not long lived in the soil. Dormancy: The seed of dandelion are not dormant and can germinate immediately in the same year that they mature of the plant. Dandelion captures space in forage crops and in no-till systems. It is not competitive for light but captures soil moisture and nutrients.
What can you do with the roots of a dandelion?
And the roots of dandelions can serve as a coffee substitute when baked and ground. ( Hint: if you are a real coffee aficionado, don’t try this .) Hey, when life gives you lemons, make lemonade, or in this case if you have a yard full of Dandelions eat’em and drink’em. Apparently, you can make green and yellow dyes from the flowers, too.
