Find out how much cellulose is made by all the plants in the biosphere and compare it with how much paper is manufactured by man,and hence determine the annual consumption of plant material by man. What a loss of vegetation!

Statement $P$ : Disaccharides can undergo hydrolysis by boiling with dilute acids or by reacting with appropriate enzymes.
Statement $Q$ : The result of hydrolysis is the release of their constituent monosaccharide units.
