Question

In the following diagram, which one of the leaves show more absolute growth?

• A. A
• B. B
• C. Absolute growth is equal
• D. Absolute growth is absent

Answer 1

The correct option is C Absolute growth is equal

Quantitative comparisons between the growth of living system can also be made in two ways: (i) measurement and the comparison of total growth per unit time is called the absolute growth rate and (ii) the growth of the given system per unit time expressed on a common basis, e.g., per unit initial parameter is called the relative growth rate.
Two leaves, A and B, are drawn that are of different sizes but shows equal absolute increase in area in the given time to give leaves, A${}^1$ and B${}^1$. However, one of them shows much higher relative growth rate.
