Where does the oxygen produced in photosynthesis come from?
The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.
What is 6CO2 6H2O?
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2. In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll.
Where does the carbon in photosynthesis come from?
The carbon dioxide required for photosynthesis comes from the air. It enters leaves through the stomata . Water enters the plant through the roots, and is transported to the leaves in the xylem .
Where does energy for photosynthesis come from?
The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
Where does the oxygen come from?
At least half of Earth’s oxygen comes from the ocean. Scientists estimate that 50-80\% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
What does this equation means 6CO2 6H2O energy → C6H12O6 6O2?
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen. The equation depicts the process by which plants and some bacteria produce glucose from carbon dioxide and water using energy from sunlight, as indicated in Jones and Jones’ Advanced Biology Textbook (1997).
Where is oxygen produced in plants?
All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.
