Light wavelengths and photosynthesis
WebMore important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis. WebSep 12, 2024 · Introduction. Light is the original source of energy for plant photosynthesis and growth. A wide range of signals and information for morphogenesis and many other physiological processes is triggered by light (Chen et al. 2004).Different characteristics of light such as spectral composition (wavelengths), intensity, duration and direction can …
