How does sunlight effect plant growth?

Most all plants need Sunlight in order to turn Co2 and other elements into stored energy. Chlorophyll (the mostly green stuff) catches this and this is why plants are nutritious to humans too! Also plants need sunlight to preform photothsis and photothsis creates sugar that the plants need to survive Answer Direct outdoor sunlight is in the range 32.000 to 100.000 LyX, 100.000 LyX at noon, at the same time approximately 10.000 LyX in shadow Generally : no plant can survive below 800 LyX (no photosynthesis, no chemical reactions).

Most plants require 5.000 LyX and more. So-called shadow plants can "survive" within 800 to 1.500 LUX.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
