GENERAL KNOWLEDGE

Detailed explanation-1: -Mangroves that grow in marshy areas are not able to obtain oxygen from the soil. The roots grow out of the soil and extend towards the upward direction. These roots possess multiple pores that help with respiration in plants and hence they are called breathing roots.

Detailed explanation-2: -These plants fail to absorb oxygen from the soil in the marshy areas and hence the roots extend vertically upward from the soil. These roots have small pores in them which helps with exchange of gasses between the plant and atmosphere and hence are called breathing roots.

Detailed explanation-3: -D. Mangrove plants. Hint: Pneumatophores or breathing roots are respiratory roots found in halophytes such as mangroves. They often grow in saline swamps, so breathing roots come out of the water to consume oxygen.
