Two leaves, A and B, are of different sizes but shows absolute increase in area in the unit time to give leaves A 1 and B 1 . Find out the absolute growth and relative growth rate of both the leaves.

Step-by-step solution

Growth rate is measured by increased growth per unit time. Growth in an organism or its part can occur in many different ways. When the total growth of the living system is measured and compared in a particular unit time is referred as absolute growth rate. This growth rate is for that particular living system in that time interval and not compared with other living system. Absolute growth = Growth in given time period = Growth (final time) - Growth (initial time) Absolute growth of A = Growth A'-Growth A = 10 - 5
