Expenditure of Energy by Plants.The energy of the plant is, af we have seen, derived originally from the kinetic radiant energy 01 the sun.
The absorption of these rays implies that the pigment absorbs radiant energy from the sun, and gives us some explanation of its power of constructing the carbohydrates which has been mentioned as the special work of the apparatus.
He recalled his mother, her heavy features nonetheless made beautiful by her radiant smile as she swung a waist-high Talal around.
The gas developed by the coal near the mouth of the retort is quickly washed out into the ascension pipe by the push of the gas behind, and the period for which it has been exposed to the radiant heat from the walls of the retort is practically nil; whilst the gas evolved in the portion of the retort farthest from the mouthpiece has only its own rate of evolution to drive it forward, and has to traverse the longest run possible in tile retort, exposed during the whole of that period to radiant heat and to contact with the highly heated surface of the retort itself.
The source of energy which is the only one accessible to the ordinary plant as a whole is the radiant energy of the rays of the sun, and its absorption is mainly due to the properties of chlorophyll.
A closed stove acts mainly by convection; though when heated to a high temperature it gives out radiant heat.
Princess Mary on the other hand instead of going away sank into an armchair, and looked sternly and intently at him with her deep, radiant eyes.
The outcome of the whole round of changes, however, is the fixation of a certain part of the radiant energy absorbed by the chlorophyll.
She was already pale, but on hearing these words her face changed and something brightened in her beautiful, radiant eyes.
