NEET BIOLOGY

Detailed explanation-1: -In halophytes, such as mangrove trees, there are respiratory roots called pneumatophores. Halophytes’ breathing roots protrude into the water to absorb oxygen because they flourish in saline marshes. Additionally, it releases an excessive amount of CO2. Lenticels are tiny pores that make this possible.

Detailed explanation-2: -Assertion : Presence of pneumatophores (the respiratory roots) is a special adaptation of hydrophytes. Reason: Pneumatophores help to take up oxygen from the atmosphere and transports it into the main roots.

Detailed explanation-3: -Pneumatophores are respiratory roots found in halophytes like mangrove trees. Because halophytes thrive in salty marshes, their breathing roots emerge from the water to take oxygen.

Detailed explanation-4: -Some branches of tap root grow vertically upward and come on the surface of soil. These roots are called pneumatophores and have minute pores called pneumathodes or lenticels by which air entered the plant and get oxygen for respiration.

Detailed explanation-5: -They are present in Rhizophora and mangrove trees.
