Question

Why is photosynthesis called the reverse process of combustion?

Answer 1

Photosynthesis is a process through which plants produce oxygen & energy in form of sugar from sunlight, water, & carbon dioxide.

Combustion is a process that occurs when a material combines quickly with oxygen and produces heat.

Explanation of the difference between combustion and photosynthesis:

Photosynthesis	Combustion
Photosynthesis is a process in which carbon dioxide and water combine to produce glucose, which is then broken down by lipids and other enzymes.	Energy is released during combustion, but it is consumed by plants during photosynthesis.
Photosynthesis occurs in the presence of sunlight in the green leaves of plants.	Combustion occurs continuously without the presence of sunlight.
Energy is created during photosynthesis.	Energy is lost during combustion.
