Hi, I'd like to know if plants can take in sugar through the roots ? I'm doing some simple in-vitro experiments with orchids. I follow some procedures without really understanding why. Table sugar is used as an ingredients and those orchid seeds grows in the medium. Sugar is said to be a carbon source. do you know how the orchid protocorms takes in the sugar ? For plants grown in the soil or pots, is it possible for roots to take in glucose, carbohydrates, polysaccharides ( complex sugars?) and molasses directly ? Thanks.

I have been thinking, this energy used to power shuttles into space. It is lost in space instead of recycled on earth. If one day, space travel becomes common, will this depletes earth's resources ?

Hi everyone, First post here. I have several questions. Is anyone familiar with Carey Reams and Biological Theory of Ionization ? I'm looking for general info and loopholes of it, but I can't find anything concrete using google. Is it pseudo-science or do anyone believe in it ? I'm also looking for info of whether high Brix farming or gardening is real science or a fad. Thanks !
