MARSH
Marsh Plants are characterised by luxuriant growth and often have large leaves. Close to the water's edge, there is no shortage of water for growth. Plants in this region can therefore afford to have large leaves since excessive loss of moisture from the foliage is not a problem. However, because the soil is generally water logged, it tends to be also anaerobic and short of oxygen. Plants in this zone therefore often have large air spaces within their internal structure to store air, in case of shortages in the soil.
SWAMP
Many swamp plants are either partially or fully submerged underwater. This creates a difficult challenge for plants, which need oxygen to effectively undergo photosynthesis. To accommodate this, many swamp plants have hollowed stems that transport oxygen down to the roots where they are needed. Others have special air spaces in their roots called aerenchyma through which water-based oxygen ions can enter the roots and be used for survival.

Explanation:
Plants which grow in marshlands or swamps have pneumatophores. These are vertical or negatively geotropic roots that arise from the underground roots. These are also called breathing roots as they bear openings called lenticels for gaseous exchange.
