Why is not any one parameter good enough to demonstrate growth throughout the life of a flowering plant?

(N/A) In plants,growth is defined as an irreversible increase in size,which is fundamentally linked to an increase in the amount of protoplasm.
Measuring the growth of protoplasm is complex and involves various parameters such as the fresh weight,dry weight,length,area,volume,and cell number of the plant tissues.
Since different parts of a plant grow at different rates and utilize different physiological processes,relying on a single parameter (like length or weight alone) fails to capture the comprehensive developmental changes occurring throughout the life cycle of a flowering plant.
Therefore,multiple parameters are required to accurately demonstrate and quantify growth.
