Question

Which adaptation is not found in aquatic plants?

• A. Conducting tissue system is under developed
• B. Root system well developed
• C. Presence of arenchyma in plant organs
• D. Plants covered with mucilage

Answer 1

The correct option is B Root system well developed

• The stems of many aquatic plants (hydrophytes) have aerenchymatous tissue to increase buoyancy.
  
• Generally, hydrophytes have poorly developed root systems. This is because their other adaptations allow them to gain all the nutrients they need from the surrounding water.
  
• Hydrophytes do not need a well-developed vascular system (conducting system).
  
• The plant body is covered with mucilage. Mucilage protects the plants from epiphytes, pathogens, and animals. It also functions as a lubricant and reduces friction against water current.
  

So, the correct statement is 'Root system well developed'.
