NEETBotanyPlant - Growth and Development
In the formula Lt = L0 + rt, what does ‘r’ represent?
Options
- ALength at time zero
- BLength at time zero
- CGrowth rate / elongation per unit time
- DDifference in length
Correct answer
C. Growth rate / elongation per unit time
Step-by-step solution
On plotting the length of the organ against time, a linear curve is obtained. Mathematically, it is expressed as Lt = L0 + rt Lt = length at time ‘t’ L0 = length at time ‘zero’ r = growth rate / elongation per unit time.
