Relative growth is the increase in size relative to the size of the plant leaf present at the start of a given time interval. It can be also expressed as percentage increase.

To calculate the relative growth rate (RGR), we need to determine the change in size and the initial size of the leaves.

For Leaf A:

Initial size = 5 cm2

Change in size = 5 cm2

RGR = (Change in size / Initial size) * 100

RGR = (5 cm2 / 5cm2) * 100

RGR = 100%

For Leaf B:

Initial size = 50 cm2

Change in size = 5 cm2

RGR = (Change in size / Initial size) * 100

RGR = (5 cm2 / 50cm2) * 100

RGR = 10%

Therefore, the correct answer is:100%, 10%

Hence, option 1 is the correct answer
