Answer:
The correct answer is - *It relates directly to the characteristics of the plant's environment*
Explanation:
The relationship between structure and function can be represented by the leaf structure as the structure of a particular plant leaf gives an idea about the characteristics of the environment it is habituated.
In the dry area or deserted area, leaves are modified into spikes to save water in order to lower transpiration, number of waxy coating, number of chlorophyll, and other modifications that give an idea about the environment and light intensity, and other characteristics.
