Reduction in vascular tissue, mechanical tissue and cuticle is characteristic of :
  1. Hydrophytes
  2. Xerophytes
  3. Mesophytes
  4. Epiphytes

Solution

Hydrophytes are plants that grow in water or in very wet conditions. Due to their aquatic environment, they do not need well-developed vascular tissues (xylem and phloem) or mechanical tissues (like collenchyma or sclerenchyma) to support their structure, as water provides buoyancy. They also have a reduced or absent cuticle because water loss is not a concern. Xerophytes, in contrast, are adapted to dry environments and often have well-developed vascular tissues, thick cuticles, and specialized mechanical tissues to prevent water loss. Mesophytes are plants that grow in moderate conditions, neither too dry nor too wet, and have typical vascular and mechanical tissue development. Epiphytes grow on other plants but are not parasitic, and their adaptations are geared towards water and nutrient absorption from the air, not necessarily the reduction of vascular or mechanical tissue.
