How does the angle of light effect plant growth?

Question

I need creditable information on how the angle of light effects the growth of a plant.

Answer 1

the part of the plant that receives ligth will grow slower. as a result a plant bends towards light.

Answer 2

Plants have a tendancy to follow the light. Some prefer in the shade. Actually, it depends on the kind of plant.

Answer 3

In this context, it's "affect" & "affects" not "effect" & "effects"...

But, to get to your question, I found this:

"Quantity describes intensity or concentration. The quantity of light decreases with distance and angle from the source. Light quantity is measured in foot candles.

Plants receive maximum quantity of sunlight in summer and minimum in winter because of the angle at which the wavelengths of light hit the plant surface. Plants must be positioned 2 to 6 inches from an artificial light source for the light to be effective."

Answer 4

Sunlight in the morning and evening contains more of yellow and red wavelengths and there is more absorption of light in the air layers.The afternoon light contains light of all wavelengths, so photosynthesis is more effective. More the photosynthesis...more is the growth of plants. However indoor plants grow more in shade rather than direct sunlight.
