we already know how photosynthesis is done ; so why cant we creat “artificial plants” that take CO2 and gives O2 and energy in exchange?
In: Biology
You have energy on the wrong side there. It takes CO2 and energy and gives O2 in exchange.
Also organic photosynthesis is incredibly complicated and uses a ton of membranes, enzymes and proteins that would be very hard to synthesize on even a tiny scale never mind a useful one.
Your question is like asking “we know how cellular respiration works so why can’t we create “artificial animals”?” Like, just grow entire frogs and monkeys in a test tube, or 3D print them?
If that seems obviously absurd for our current tech, be aware that plants are just as complicated as animals in terms of cell machinery.
If your question is just about using sunlight to convert CO2 to O2 (not actually artificial entire plants), then [yes that absolutely is a thing that exists and is currently a huge area of upcoming research.](https://link.springer.com/chapter/10.1007/978-3-030-04949-2_5)
