Define photosynthesis
Answers
Explanation:
Answer:
Photosynthesis is the process by which living plant cells which contains chlorophyll, produce food substances like glucose and starch from carbon dioxide and water by using light energy.
It provides food for all living beings including animals and humans.
It provides us oxygen to breathe in by releasing oxygen into the atmosphere.
Photosynthesis can occur in two phases
Light Reaction and
Dark Reaction
Light reaction traps the energy by using chlorophyll and use that energy in splitting water molecules into hydrogen and oxygen which is called photolysis.
Dark reaction transfer the hydrogen from NADPH through a series of chemical reactions to combine with carbon dioxide to produce glucose by using energy from ATP
Answer:
Photosynthesis
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that , through cellular respiration , can later be released to fuel the organism's metabolic activities . 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 . the process by which green plants and certain other organisms transform light energy into chemical energy .
