Photosynthesis Overview: Photosynthesis Review Worksheet Answer Key
Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy stored in glucose. It is a vital process for life on Earth, as it provides the oxygen we breathe and the food we eat.
The key reactants in photosynthesis are carbon dioxide and water. The products are glucose and oxygen.
The overall chemical equation for photosynthesis is:
6CO2+ 6H 2O + light energy → C 6H 12O 6+ 6O 2
Light-Dependent Reactions
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts. Light energy is absorbed by chlorophyll and other pigments, which excite electrons. These electrons are then passed through an electron transport chain, which generates ATP and NADPH.
Calvin Cycle (Light-Independent Reactions)
The Calvin cycle occurs in the stroma of chloroplasts. ATP and NADPH from the light-dependent reactions are used to fix carbon dioxide into glucose.
Factors Affecting Photosynthesis, Photosynthesis review worksheet answer key
The rate of photosynthesis is affected by a number of factors, including light intensity, temperature, carbon dioxide concentration, and water availability.
Importance of Photosynthesis
Photosynthesis is essential for life on Earth. It provides the oxygen we breathe and the food we eat. It also plays a role in the global carbon cycle.
Common Queries
What is the overall chemical equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
What is the role of chlorophyll in photosynthesis?
Chlorophyll absorbs light energy and transfers it to electrons, initiating the electron transport chain.
What are the products of the Calvin cycle?
The Calvin cycle produces glucose, a sugar molecule that serves as the primary energy source for plants.
What factors can limit photosynthesis?
Photosynthesis can be limited by light intensity, temperature, carbon dioxide concentration, and water availability.
What is the importance of photosynthesis for the global carbon cycle?
Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic matter, regulating the Earth’s climate.
