Light is the basic requirement for photosynthesis. Chlorophyll, beta-carotene and other pigments group together in the membrane and absorb different colors of light.

Light plays a key role in the light stage of photosynthesis, wherein the plant absorbs light energy and triggers electron transfers.

Moreover, Cope and Bugbee explored the importance of green light for plant growth and development and explained that green light permeates deeper into the plant, further than red and blue, and therefore provides additional photosynthesis beyond the red/blue top leaf saturation levels. Light is the energy source for the process of CO2 fixation get to completion: 6CO2 + 6H2O –> C6H12O6 + 6O2 This is a non-spontaneous reaction ∆G>0. The light-dependent reactions of photosynthesis convert solar energy into chemical energy, producing ATP and NADPH or NADH to temporarily store this energy. This topic often proves very challenging for students and they can easily become confused, making simple mistakes such as pigments absorb light rather than absord light energy. Light-dependent reaction and Dark reaction. Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze how users use the site. Grana are the stacked membrane structure within chloroplasts; the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis.

Photosynthesis is a process by which plants store light enegry in the form of chemical energy. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis. This occurs in the plant’s thylakoid membrane, in which light energy is turned into chemical energy. In photosynthesis energy is transferred to ATP in the light-dependent stage and the ATP is utilised during synthesis in the light-independent stage. CO2+H2O=C6H12O6 is a typical example of endothermic process so plants need to supply energy for this process.

Students should know in detail the chemical process of photosynthesis.

Light Dependent reaction does on as follows:- Forming a bond is an endothermic process. Cookie Name Accept; Google Analytics This website uses Google Analytics, a web analytics service provided by Google, Inc. ( 'Google'). In the process of photosynthesis, two major steps occur, namely: Calvin Cycle (light independent reaction) and the Z-Scheme (light dependant reaction). Green plants absorb light in their leaves and convert it to energy by photosynthesis. Photosynthesis has two steps. In oxygenic photosynthesis , H 2 O serves as the electron donor to replace the reaction center electron, and oxygen is formed as a byproduct.
