In hydrophytes, vascular tissue and mechanical tissue are reduced. Cuticle is either completely absent or if present, it is thin and poorly developed. In xerophytes, cuticle is heavy, well-developed. Vascular tissue and mechanical tissue are well-developed and differentiated. In mesophytes, cuticle in aerial part is moderately developed. Vascular and mechanical tissues are fairly developed and well differentiated.
