Why do photosynthesizing plants appear green?
The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Why do plants reflect green light and not red?
The simple answer is that although plants absorb almost all the photons in the red and blue regions of the light spectrum, they absorb only about 90\% of the green photons. If they absorbed more, they would look black to our eyes. Plants are green because the small amount of light they reflect is that color.
Why are green wavelengths reflected?
The set of wavelengths that a pigment doesn’t absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.
Why do leaves appear green even it absorbs other colors of light?
Green plants are green because they contain a pigment called chlorophyll. As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.
Do plants use green light for photosynthesis?
Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture. The majority of green light is useful in photosynthesis.
Why do different wavelengths of light affect photosynthesis?
Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn’t).
Why are leaves mostly green in colour?
The green coloration in the leaves of most plants is due to the presence of chlorophyll, a pigment used to absorb energy from the sun.
