Suppose two leaves have grown by 5 cm2 in a day, the initial size of leaf A was 5 cm2 and B was 50 cm2, what would be the RGR?
100%, 10%
100%, 100%
25%, 100%
100%, 25%
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
