Plant Specimens:

Here are the observations regarding the adaptations of the specimens:

• Plant Specimens:

  • Agave sisalana: Has a thick cuticle, reduced leaves, and spines for water conservation.
  • Cactus: Features succulent stems for water storage, spines for protection, and shallow roots for quick water absorption.
  • Eichhornia crassipes (water hyacinth): Possesses air-filled tissues (aerenchyma) for buoyancy and waxy leaves to repel water.
  • Citrus sinensis: Has thick, leathery leaves to reduce water loss and oil glands for protection against herbivores.

• Animal Specimens:

  • Lizard: Characterized by dry, scaly skin to prevent water loss, a long tail for balance, and sharp claws for climbing.
  • Frog: Has moist skin for cutaneous respiration and webbed feet for swimming.
  • Fish: Features a streamlined body for swimming and gills for oxygen extraction in water.
  • Cockroach: Possesses a hard exoskeleton for protection and spiracles for efficient gas exchange.
