Study Notes
Overview of Photosynthesis
- Photosynthesis is the process where plants, algae, and some bacteria use sunlight to synthesize sugars.
- Key reactants include carbon dioxide (CO2) and water (H2O).
- Carbohydrates, primarily glucose, are the main products of photosynthesis.
Process of Photosynthesis
- Photosynthesis occurs in chloroplasts, the organelles located in plant leaves.
- The first stage involves light reactions where sunlight is absorbed by chlorophyll, splitting water into hydrogen and oxygen.
- Oxygen is released as a byproduct during the light reactions.
Stages of Photosynthesis
- Dark reactions (Calvin Cycle) utilize hydrogen and carbon dioxide to create glucose, the primary energy source for the plant.
- The overall reaction can be summarized with the equation: 6CO2 + 6H2O → C6H12O6 + 6O2.
Chlorophyll’s Role
- Chlorophyll is crucial for absorbing light and gives leaves their green color.
- The prefix "chloro-" means green, indicating its connection to the photosynthetic process.
Environmental Requirements
- For photosynthesis, plants require sunlight, carbon dioxide (obtained from air through leaves), and water (absorbed through roots).
- Common sources of CO2 include air, factories, and vehicles.
Functions and Importance
- Glucose produced during photosynthesis is used by plants for energy, growth, or stored for later use.
- Oxygen produced is essential for respiration in animals and humans.
Connection to Energy
- Sunlight energy is converted into chemical energy in the form of glucose through a combination of light and dark reactions.
- Photosynthesis allows plants to function as producers within ecosystems, supporting life by providing energy.
