IRRITABLE PLANTS
WHAT THEY AKE AND WHAT THEY DO. A plant is a sensitive organism; it possesses the quality known as irritability, one 01 cne essential properties of living protoplasm (writes Dr A. C. Seward, KK.s., Master of Downing College, in " Plants: What Tney Are and Wnat They do "). it is au.e to complete its aeveiopment *i supplied with a few salts, water, and air. From the elements avai.aoie in ordinary ground wa*er and tne carbon in the air it builds up its body. By reason of its unique power of utilising radiant energy from the sun it obtains carbon for the manufacture of carbo-hydrates and pro terns, borne carbo-hydrates can be made artificially, thougn not as the plant makes them; no proteins have so far been made by man. The green piant, in short, controls the food supply and the life of the whole animal kingdom.
