When was the first photosynthesis?

Answer 1

Well the first photosynthesis was at the start of time because otherwise we wouldn't have any air and therefore not be alive. So to say is simply photosynthesis has been around forever just like trees.

This is not correct at all.....completely false.

i think the first thing to photosynthesise was bacteria, it may be called cyanobacteria, i am not completely sure. but no, things have not been photosynthesising forever as the temperature did not cool down enough for millions or billions of years, and put it this way, humans did not evolve for billions of years, so we werent made when the earth was "formed"

Answer 2

Jan Ingenhousz was a Dutch-born British physician and scientist. He is credited for the discovery of the process of photosynthesis, wherein green plants in sunlight absorb carbon dioxide and release oxygen.

Answer 3

Jan van Helmont was the first to begin studying the process in the 1600's. Jan Ingen-Housz is credited in 1778/1779 for actually discovering the influence of sunlight on plants.

Answer 4

He demonstrated that leaves absorb CO2 and release oxygen only in sunlight by observing plants in both darkness and in sunlight.
