Light - Quality, Intensity, and Duration | NEET

This section distinguishes between three different aspects of light that affect photosynthesis. Light quality refers to the wavelength or color of light - whether it's blue light, red light, green light, etc. Light intensity refers to the brightness of light - how much light energy is arriving at the plant. Light duration refers to the length of exposure to light - how long the light is present. These three aspects are different properties of light and must be considered separately when discussing light as a limiting factor. Understanding these distinctions is crucial because plants respond differently to changes in each aspect. For example, increasing light intensity will increase photosynthesis up to a point, but increasing light wavelength in the far-red region (beyond what plants can use) won't increase photosynthesis. Duration affects daily photosynthesis accumulation but is somewhat fixed for outdoor plants based on season. The section sets up the next part which will discuss specific responses to light intensity.
