what is photosynthesis ?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

what is chlorophyll ?

It's basically a group of green pigments used by organisms that convert sunlight into energy via photosynthesis.

First used in 1819, the noun chlorophyll derives from the Greek words khloros, meaning "pale green" and phyllon, meaning "a leaf." Plants use chlorophyll to trap energy from the sun.

what is history ?

History is the study of life in society in the past, in all its aspect, in relation to present developments and future hopes.

It is the story of man in time, an inquiry into the past based on evidence.
