Question

In above diagrams, A and B are initial areas of leaves. A′ and B′ are areas of leaves after growth. Which of the following is correct ?

Options

A.Both relative and absolute growth of leaves are same
B.Absolute growth same, but relative growth different
C.Absolute growth different, but relative growth same
D.Both absolute and relative growth of leaves are different

Solution

Absolute gowth = increase
Relative growth = × 100
Leaf ′A′ Absolute growth = 12.5 - 10 = 2.5 cm2
Relative growth = × 100 = 25%
Leaf ′B′ Absolute growth = 50 - 40 = 10 cm2
Relative growth = × 100 = 25%
