NEETBotanyPlant - Growth and Development
In the formula Lt = L0 + rt, what does ‘Lt’ represent?
Options
- ALength at time zero
- BLength at time ‘t’
- CGrowth rate
- DElongation per unit time
Correct answer
B. Length at time ‘t’
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.
