Content: Apart from plants, photosynthesis is also found to occur in blue-green algae. What Happens During Photosynthesis
It involves a chemical reaction where water, carbon dioxide, chlorophyll, and solar energy are utilized as raw materials (inputs) to produce glucose, oxygen, and water (outputs). Photosynthesis Equation
Stages of the Process
Photosynthesis occurs in two stages: 1) The Light-dependent Reaction
Takes place in the thylakoid membranes of chloroplasts only during the day in the presence of sunlight
High-energy phosphate molecules adenosine triphosphate (ATP) and the reducing agent NADPH are produced with the help of electron transport chain
2) The Light-independent or Dark Reaction ( Calvin cycle)
Takes place in the stroma of chloroplast in the absence of light that helps to fix carbon
ATP and NADPH produced in the light reaction are utilized along with carbon dioxide to produce sugar in the form of glucose
Factors Affecting the Rate of Photosynthesis
Intensity of Light: The higher intensity of light increases the rate of photosynthesis
Temperature: Warmer the temperature, higher the rate of photosynthesis. The rate is highest between the temperatures of 25° to 35° C, after which it starts to decrease
Concentration of Carbon dioxide: Higher concentration of carbon dioxide increases the rate of photosynthesis until it reaches a certain point, beyond which no further effects are found
Although all the above factors together interact to affect the rate of photosynthesis, each of them individually is also capable of directly influencing the process without the other factors and thus called limiting factors. Importance of Photosynthesis
It serves two main purposes that are essential to support life on earth: Producing food for organisms that depend on others for their nutrition such as humans along with all other animals
Synthesizing oxygen by replacing carbon dioxide in the atmosphere
