Final answer:
Swamp forest species in the tropics have adaptations like stilt roots and pneumatophores to thrive in wet areas with little oxygen. These adaptations help with support and gas exchange. Examples include mangroves, cypress trees, and wild rice.
Step-by-step explanation:
Many swamp plants in the tropics have adaptations such as stilt roots and pneumatophores to thrive in wet areas with little oxygen. Stilt roots, seen in mangroves and cypress trees, grow aboveground to provide support to the tree. Pneumatophores, also found in some mangroves and cypress trees, are upward-growing roots specialized for gas exchange. They contain pores and pockets of tissue that facilitate the exchange of gases, including oxygen.
Wild rice, an aquatic plant, has a specific adaptation called aerenchyma. It has air-filled tissue in the root cortex that allows oxygen to diffuse down to the root tips, even in oxygen-poor bottom sediments.
