High light intensity on photosynthesis
WebWhen light is absorbed by one of the pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level (forming P680*). The high-energy electron is passed to an acceptor molecule and replaced with an electron from water. WebIt was shown that the photoinhibition which follows exposure of intact leaflets of low light-grown bean plants to high light intensity in normal air is essentially similar to that which occurs when ... Further evidence for dissipative energy migration via triplet states in photosynthesis. The protective mechanism of carotenoids in ...

WebIntroduction. Leaf hydraulic conductance (K leaf), which refers to the efficiency of liquid water transport through the leaf, is an important constraint on photosynthesis rates … WebHigh absorbance at a particular wavelength means that pigment is collecting that light at that wavelength to harvest energy. Low absorbance means that the plant is reflecting that …
WebDec 5, 2024 · As the light intensity increases, the rate of photosynthesis also increases. However, there is a point at which the rate of photosynthesis levels off. This is because the reactions of photosynthesis are limited by the availability of enzymes. Enzymes are proteins that catalyze chemical reactions. WebNov 22, 2016 · As light intensity increases, so does the rate of photosynthesis, up until a point. Photosynthesis, specifically the light reactions, require light to occur. The light's …
WebPlants require solar energy to grow through oxygenic photosynthesis; however, when light intensity exceeds the optimal range for photosynthesis, it causes abiotic stress and physiological damage in plants.
