Question

Pneumatophores are typical of plants (particularly trees)

A) in arid environments.
B) exposed to fluctuating water levels.
C) flooded once each year.
D) in salt marshes.

Answer 1

Pneumatophores are specialized roots found in plants like mangroves that grow in coastal waters with low oxygen, enabling them to thrive in salt marshes.

Step-by-step explanation:

Pneumatophores are specialized roots that are typical of plants in environments where the soil is saturated with water and oxygen levels are low. A notable example of such plants is mangroves (Rhizophora sp.), which can be found in coastal waters and produce these specialized roots to help them obtain oxygen in oxygen-poor environments. Thus, the correct answer to the question is that pneumatophores are typical of plants found in salt marshes (D).

These roots allow mangroves to thrive in habitats with fluctuating water levels, where traditional below-ground roots would suffocate due to the lack of oxygen.
