Light is necessary in the process of photosynthesis to produce ATP and a reducing substance. Photosynthesis occurs in two stages. In the first stage, light-dependant reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH (a reducing substance).
Light is essential for photosynthesis because plants need it energy to create glucose, which they store for later use as an energy source for cells. Plants and several other photosynthetic organisms use light energy to change water, carbon dioxide and minerals into oxygen and organic compounds packed with energy.
This energy is necessary for the production of glucose, which provides usable energy for the plant. The chloroplasts contain the green pigment chlorophyll, which absorbs the sun’s light. Two other required ingredients for photosynthesis are carbon dioxide and water.
In order for photosynthesis to happen it is not only depend on light. The rate of photosynthesis can become less not only because they isn’t sufficient light but because it is limited by other factors which can be, nutrients, water, carbon dioxide. Photosynthesis is the process whereby radiant energy is converted into chemical energy.

What is the purpose of light in photosynthesis experiment?
The light reaction is used to convert sunlight into chemical energy stored in ATP and another energy storage molecule called NADP. The light-independent reaction or Calvin Cycle takes carbon dioxide and fixes it in three-carbon molecules which will eventually be synthesized into glucose.
Why does photosynthesis need carbon dioxide?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Why do plants need carbon dioxide?
Carbon dioxide (CO2) is an essential component of photosynthesis (also called carbon assimilation). Photosynthesis is a chemical process that uses light energy to convert CO2 and water into sugars in green plants. These sugars are then used for growth within the plant, through respiration.
What are the 3 product of photosynthesis?
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
What two main products result from photosynthesis?
Photosynthesis takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product.
What are the 3 reactants of photosynthesis?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
What are the 3 reactants and 2 products of photosynthesis?
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas.
What are the products of photosynthesis products?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
What are the products of photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
What are 3 products of photosynthesis?
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
