The value of a leaf

Abstract:
The value of a leaf to a plant depends on the fate of its exported assimilates. When these are translocated and used in the growth of new leaves they contribute to further carbon assimilation. The result is that their value to the plant is greatest while they are young. In contrast, when assimilates are translocated to storage, assimilates produced early and late in the life of a leaf are of equal value. This arguments is developed in relation to the optimal distribution of mineral resources and defenses during the life of leaves.

P-value
P-value stands for the probability value. P-value is the probability that, if the null hypothesis is true, the results from another randomly selected sample will be as extreme or more extreme as the results obtained from the given sample.
A large P-value calculated from the data indicates to not reject the null hypothesis. But a higher P-value does not mean that the null hypothesis is true. The smaller the P-value, the more unlikely...
