  1. Dryness bear capacity

The capacity of moss plants to bear dryness is one of their most essential adaptations. Java moss has evolved many systems to assist it in growing in dry environments. Moss grows faster in moist conditions.

For example

  • The plant can become dormant
  • Conserving energy by shutting down its metabolic functions.
  • It may also lower its surface area by folding up its leaves, which helps to limit water loss.
  1. Exchange of Gases

When cultivated in the absence of water, moss must rely on air oxygen. Java moss can evolve specialized structures known as pseudopodia. They allow it to collect oxygen from the air. These structures also aid in the removal of excess carbon dioxide from the plant.

  1. Root structure

Java moss receives food through its leaves and stems when cultivated in water. When cultivated in the absence of water, however, it must rely on nutrient sources through its roots. Java moss uses its roots to acquire nutrients from the soil and surrounding environment.

Java moss develops specialized root structures known as rhizoids. These structures are thin, and hair-like. They help Java moss in absorbing nutrients from the surrounding soil.

  1. Leave structure

Java moss is frequently exposed to direct light. It can harm the sensitive tissues of Java moss.
