I haven’t written on this blog since no one’s viewing my blog. Now I’m feeling that my writing sense is getting much worse than before. That’s why I wanna start with a simple topic, about the cause of plants color.
Before talking about plants, let’s begin our discussion from what makes things the color they are. Around us, in our homes, at work, in nature, in space , everywhere has a color, of some sort. The colour of anything we observe depends upon a few factors. Firstly – Everything is made up of electrons and atoms. How something will look when bathed in light, is governed by these atoms and electrons. Different materials, objects and items have a different make up of atoms and electrons. Any object, by its nature, will, when exposed to light, do one of the following to that light: (1) reflection and scattering, (2) absorption, (3) transmission (4)refraction
However, what happens when leaf surface is exposed to the sunlight or other white light? Certain molecules will absorb certain colors of light. The light that isn’t absorbed is reflected, which is what our eyes see. Plants have a substance called chlorophyll in them. Large numbers of chlorophyll molecules acts as the antenna that actually harvest sunlight and start to convert it in to a useful form. Chlorophyll molecules absorb blue light and some red light. The other colors are reflected resulting in the green color that we associate with plants.
That’s all for today!
