Importance of studying leaf morphology

1. For plant description
2. For determining plant productivity
3. To determine the physiological maturity of plant as in Cotton plant and Eucalyptus.
4. For ornamental value.
5. Heterophylly (presence of leaves of more than one shape e.g. Limnophila) have adaptive significance. The finely dissected leaves are adapted to submerged conditions where entire leaves are aerial.
