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 is same, but relative growth is different
C.Absolute growth is different, but relative growth is same
D.Both absolute and relative growth of leaves are different
Solution
Absolute growth = 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%
Relative growth =
× 100Leaf ′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%Create a free account to view solution
