ground water and/or rain water
Plants obtain oxygen during photosynthesis from water molecules.
Plants take in carbon dioxide and water during photosynthesis. The chemical reaction for photosynthesis is 6CO2 + 6H2O C6H12O6 + 6O2.
In a photosynthesis sun light and water are used to make food for plants (except plants at the bottom of the sea).
Oxygen is one of the by-products of photosynthesis. It comes from the breakdown of water molecules in plants during photosynthesis.
The source of oxygen in photosynthesis in plants is water. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons. The oxygen is released into the atmosphere as a byproduct of this process.
The process is called photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
Carbon dioxide is the colorless gas that turns lime water milky and is taken in by plants during photosynthesis.
The oxygen released by plants during photosynthesis originates from water molecules. Plants take in water through their roots and split the water molecules into oxygen and hydrogen atoms during the light-dependent reactions of photosynthesis.
Plants use air, sunlight, carbon dioxide(CO2), and water.
Plants get the water they require for photosynthesis by absorbing from the soil through their root systems. It is then transported up the stem and to the leaves where is is used to synthesise sugars through photosynthesis.
They are converted into glucose during the process.
Plants use photosynthesis to produce their own food. During photosynthesis, plants absorb sunlight, carbon dioxide, and water to create glucose (sugar) and oxygen. These nutrients are then used by the plant for energy and growth.
