Photosynthesis Process and Products
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves several steps.
The process of photosynthesis can be summarized as follows:
- Light Absorption: Chlorophyll, the green pigment found in chloroplasts, absorbs light energy from the sun.
- Light-Dependent Reactions: The absorbed light energy is used to split water molecules into hydrogen ions (H+), electrons (e-), and oxygen (O2) through a process called photolysis. The released oxygen is a byproduct and is released into the atmosphere.
- Calvin Cycle (Light-Independent Reactions): In this phase, the energy captured from the light-dependent reactions is used to convert carbon dioxide (CO2) into glucose (C6H12O6). This process requires ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) as energy sources.
The products of photosynthesis are:
- Glucose: The primary product of photosynthesis, glucose, is a simple sugar that serves as a source of energy for the plant. It is used for various metabolic processes and is stored in the form of starch or used to produce other organic compounds.
- Oxygen: The release of oxygen during photosynthesis is vital for the survival of organisms that depend on it for respiration. Oxygen is released into the atmosphere as a byproduct of the light-dependent reactions.
Therefore, the correct answer is A: Glucose and oxygen.

Photosynthesis Process:
Photosynthesis is the process by which plants utilize sunlight to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
Production of Glucose and Oxygen:
During photosynthesis, plants absorb sunlight through their chlorophyll pigments. The energy from the sunlight is used to convert carbon dioxide and water into glucose and oxygen. Glucose is a simple sugar that serves as food for the plant and is essential for its growth and development. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.
Importance of Glucose:
Glucose is a vital source of energy for plants. It is used for cellular respiration, where it is broken down to release energy that the plant needs to carry out various metabolic processes. Additionally, glucose can be stored in the form of starch for later use when sunlight is not available for photosynthesis.
Role of Oxygen:
The oxygen produced during photosynthesis is released into the atmosphere. This oxygen is crucial for all living organisms, as it is used in the process of respiration to generate energy. Humans and other animals depend on the oxygen produced by plants during photosynthesis for their survival.
In conclusion, photosynthesis is a vital process for plants, as it produces glucose for energy and oxygen for respiration. This process is essential for the overall functioning of ecosystems and the balance of gases in the atmosphere.
