High light intensity on photosynthesis
WebNov 2, 2024 · More light causes more photosynthesis because plants need light to produce food. The more light they have, the more food they can make. According to the Emerson enhancement effect, the rate of photosynthesis increases when the chloroplast is exposed to a light wavelength of 680 nm and 700 nm. WebFactors limiting photosynthesis. There are a number of factors which contribute towards the process of photosynthesis. The factor which is working at the lowest level will usually be the limiting factor of the process. There are several limiting factors which can reduce the rate of photosynthesis, eg temperature, light intensity and carbon dioxide concentration.
High light intensity on photosynthesis
Did you know?
WebLight intensity is one of the factors affecting the rate of photosynthesis. Other factors are concentration of carbon dioxide, temperature and to a lesser degree, water. Light intensity directly affects the light-dependent reaction in photosynthesis and indirectly affects the light-independent reaction. 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 …
WebThe process is quite complex, and for the sake of this guide, we can use this simplified definition of photosynthesis: using light energy to split water (H 2 O) and fix carbon … 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.

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.
