Light Colour on Photosynthesis


Light travels in waves but also as little energy packets. A photon of light contains the entire visible outlook to the human eye: red, orange, yellow, green, blue, indigo and violet. Plants absorb red, orange, yellow, blue, indigo and violet wavelengths of light but reflect green. When wavelengths of light are absorbed, they are no longer available for eyes to see, which is why plants look green. Pigments also help this cause.

Plants with little light exposure grew taller because they are trying to reach the sun. They are also pale in color but change back to green when exposed to more light. But they also died out faster.



Darkness Affects Plants


How can plants grow when the main source of energy is not there to begin with? Light. Yes I am talking about light because without it the process can't work. "
    • Plants would not do well in total darkness. If a plant were to be placed in a closet with no light it would stop growing. If placed there too long, even with adequate water, it would still die because plants depend on receiving some sunlight.

      So with that being said.. how will a plant be able to grow in the dark? it won't..it will just die out.

Water Tempature Affects Plants

With Water.. if it too warm the process isn't as good as if temperature was mild.. since it uses a lot of energy if it's too hot or too cold... to cool it down for its photosynthesis process. Plants need both light and water in the process. When water is cold or at freezing temperature the photosynthesis process slows down due to the lack of energy being used as if it were to be hot.

Sunlight Affects Photosynthesis

Plants are very special in their own case in which they are the own specimen aside from a few others that can collect sunlight as energy. Plants collect 1% of the sunlight to begin the process of Photosynthesis.. If it doesn't obtain that 1% only the process of Photosynthesis can not function. With sunlight in this process it powers all the chemical reactions.




Here is the reaction itself -
6CO2 + 12H2O + sunlight ---> 6O 2 + C6 H12O 6 + 6H2 O

Pollution affecting Photosynthesis?



When disaster hits, it doesn't necessarily mean natural disaster.. Even the smallests disasters can affect everything in it's very own cycle. Pollution is a big one.. we keep doing it, sometimes knowing sometimes not knowing what it will/does to our planet. But one ultimate effect pollution has on is photosynthesis.. As pollution happens, we're destroying plants and etc. As we are destroying plants this cycle comes into conclusion as incomplete or just not being able to happen. We need plants going through the process of photosynthesis to create energy for the cycle of life. As we destroy the source of our energy we will slowly die and feel the loss in the end. Is it our fault? Yes. I honestly believe the blame is completely on us. Dating back thousands of years before humanity existed... Earth was built on this cycle to help each other. Years later, as we have built our system, we ened up interfering with this built system created by Earth... as if we have lost all respect to what is helping us live.
