An operational definition is used for a behavior so that the behavior can be properly described and understood. Without an operational definition, it would be difficult to describe behavior without being subjective. Therefore, behavior cannot be understood and cannot be correctly addressed. It is also important to understand how behavior functions so that the antecedents and consequences of behavior can be observed. Thus, what reinforces or affects the behavior can be better understood. Lastly, an operational definition is objective and specific, therefore, behavior can be described across different settings and times.

In Pinus species male cone matured earlier than female cone, this ensures success of pollination in that the male cone will be in a position to produce more pollen grains.

These pollen grains will fully occupy the female part and thus the effect will be that the cone will be fertilized by its species other than other species.
