During photosynthesis plants take in ___________ and release _________...
During photosynthesis, plants take in carbon dioxide and release oxygen. Plants take in carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. The plant then releases the oxygen into the atmosphere while storing energy in the glucose molecules.

During photosynthesis plants take in ___________ and release _________...
Answer:
Photosynthesis:
During photosynthesis, plants use sunlight, water, and carbon dioxide to synthesize glucose (a sugar) and release oxygen gas as a byproduct. This process occurs in the chloroplasts of plant cells and is responsible for the production of food and oxygen in the environment.
Input and Output:
Plants take in carbon dioxide (CO2) and release oxygen (O2) gas during photosynthesis.
Explanation:
During photosynthesis, the following reactions occur:
1. Light-dependent reactions:
- Light energy is absorbed by chlorophyll in the chloroplasts.
- Water molecules (H2O) are split into hydrogen ions (H+), electrons (e-), and oxygen gas (O2) through a process called photolysis.
- Oxygen gas (O2) is released as a byproduct.
2. Light-independent reactions (Calvin cycle):
- Carbon dioxide (CO2) molecules are taken in from the atmosphere.
- Carbon dioxide (CO2) is converted into glucose (C6H12O6) through a series of chemical reactions.
- Glucose (C6H12O6) is used as energy by the plant or stored for later use.
Therefore, the correct answer is A: Carbon dioxide, Oxygen.
