The formula to calculate the Stomatal Density (Ds) is:
\[ Ds = \frac{S}{A} \]
Where:
Stomatal density refers to the number of stomata (tiny openings on the surface of leaves) per unit area. It is an important measure in plant physiology and ecology, as it affects the plant's ability to exchange gases and regulate water loss.
Let's consider an example:
Using the formula to calculate the Stomatal Density:
\[ Ds = \frac{150}{1} = 150 \text{ stomata/mm²} \]
This means that the stomatal density for this example is 150 stomata/mm².
