How does photosynthesis work AP Bio?
AP Biology 🧬 Photosynthesis is a chemical process with the following equation: H2O + CO2 → C6H12O6 + O2. Both plants and photosynthetic bacteria are capable of this complex conversion process. The overall reaction is spurred by the energy from a photon of light striking a pigment in the chloroplast.
What is the basic process of photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
What are the two main reactions of photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle.
What’s the formula for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What are 3 important facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll.
- The two main parts of a chloroplast are the grana and stroma.
- The first stage of photosynthesis captures energy from the sun to break down water molecules.
- The second stage of photosynthesis is the Calvin cycle.
Why are plants green in color?
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
