Photosynthesis uses water and carbon dioxide to convert sunlight energy into
a
high energy triglycerides
b
oxygen and glucose (chemical energy)
c
proteins and oxygen
d
carbon monoxide and water
b
oxygen and glucose (chemical energy)
The correct answer is b) oxygen and glucose (chemical energy).
The correct answer is b) oxygen and glucose (chemical energy).
Explanation:
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight energy into chemical energy in the form of glucose. This process takes place in the chloroplasts of the plant cells.
During photosynthesis, plants use water (from the roots) and carbon dioxide (from the atmosphere) to carry out a series of reactions. These reactions happen in two main stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).
In the first stage, the light-dependent reactions, sunlight is absorbed by pigments called chlorophyll molecules in the chloroplasts. This energy is used to split water molecules into hydrogen ions (H+), electrons (e-), and oxygen (O2). The oxygen molecules are released into the atmosphere as a byproduct.
In the second stage, the light-independent reactions or the Calvin cycle, the energy stored in the ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) produced during the light-dependent reactions is used to convert carbon dioxide into glucose. This glucose serves as a source of chemical energy for the plant.
Therefore, the correct answer is b) oxygen and glucose (chemical energy), as oxygen is the byproduct and glucose is the main product of photosynthesis.
