Detailed explanation-1: -Pneumatophores, commonly found in mangrove species that grow in saline mud flats, are lateral roots that grow upward out of the mud and water to function as the site of oxygen intake for the submerged primary root system.

Detailed explanation-2: -Aquatic plants have their roots submerged in water. To facilitate gaseous exchange in such plants, roots grow erect above the ground. These roots have numerous pores in them, which helps the plant in gaseous exchange. Such roots are called breathing roots.

Detailed explanation-3: -Pneumatophores are found in the vegetation which is found in marshy and saline lakes. Knees or Pneumatophores are specialized roots developing in mangrove plants. These are found growing in saline marshes, roots growing vertically upwards.

Detailed explanation-4: -Pneumatophores are specialized roots that grow upward and allow oxygen and carbon dioxide exchange from the plant’s root system. They passively catch the air via multiple pores (Figure 10.4. 3). Some aerial roots will function as photosynthetic organs as well.

Detailed explanation-5: -There are many different types of specialized roots, but two of the more familiar types of roots include aerial roots and storage roots. Aerial roots grow above the ground, typically providing structural support. Storage roots (for example, taproots and tuberous roots) are modified for food storage.
