(2008) Visible Light Induced Water Oxidation in Photosynthesis from Green Plants.

While certain wavelengths are absorbed, others are reflected is produced, this is essentially the reason why plants are green, because the main pigment, chlorophyll a, absorbs all colors in the visible light specturm but green.


Pigments absorb light used in photosynthesis.

Therefor, the faster the rate of photosynthesis, the faster the leaves rises.
There are five matters that affect the rate of photosynthesis: light intensity, temperature, CO2, water, and the color of light in general.


of chlorophyll a and chlorophyll b in the range of visible light.

When we started this lab, we expected the highest rates of photosynthesis to be at the wavelengths of 475 nm (blue light) and 650 nm (red light), and the lowest to be at 510 nm (green light) and 570 nm (yellow light) due to the action spectrum of visible light.

and provide strong light-harvesting for photosynthesis ..


The seven foods are: red, orange, yellow, green, blue, purple, and violet.
Each of the food helps the children grow at a different rate.
Every plant has leaves that help them undergo photosynthesis is order to survive.
Within the leaves there are cells, and within the cells there are chloroplasts and within those chloroplast, there are chlorophyll.
Chloroplasts absorb sunlight and combine with water and carbon dioxide gas to produce food for the plant.
Chloroplast are green because they absorb every color except green.

Light energy - Biology-Online Dictionary

Violet-blue and red light work the best for photosynthesis because they are absorbed by pigments in the chloroplasts, while green and yellow light are reflected (transmitted).

Light energy is a form of energy and is expressed in joules


This data was compared to that of the standard action spectrum for photosynthesis of visible light (this profiles the relative effectiveness of different wavelengths of radiation in driving the process of photosynthesis).

It is also the visible light that drives photosynthesis.

If the rate of photosynthesis increases as wavelength increases, then the 650 nm light (red) will have the lowest ET50, followed in increasing order by 570 nm (yellow),
510 nm (green), and 475 nm (blue).
