What is the difference between aerial roots and prop roots

The key difference between prop root and stilt root is that prop root is an adventitious root developed from horizontally spread branches of the tree while stilt root is a type of adventitious root developed from basal nodes of the stem near the soil. Plants have a root system in order to anchor into the soil and absorb nutrients, water and minerals.

Some plants have a tap root system while other types have an adventitious root system. Prop root and stilt root are two types of adventitious roots.

Prop roots develop from horizontally spread branches of the tree while stilt roots arise from basal nodes of the stem near the soil. Moreover, prop roots grow vertically downwards the soil while stilt roots grow obliquely downwards the soil.

Prop roots appear as pillars while stilt roots appear as ropes of a tent. Both types of roots provide mechanical support to the plant. Overview and Key Difference 2. What is a Prop Root 3. What is a Stilt Root 4.

Prop root is an aerial root that develops from the horizontal branches of a tree. They look like pillars or poles. They are quite thick and long. Moreover, they grow vertically towards the soil. The main function of prop roots is providing mechanical support to the plant.

Furthermore, they support branches. They even can replace the main stem of the plant. Young prop roots are hygroscopic. They absorb moisture from the air.

Ficus benghalensis banyan tree has prop roots. Stilt root is a root that arises from basal nodes of the main stem. Stilt roots are like ropes of a tent. They grow obliquely at an angle to the stem. Aerial roots are adventitious root s. Other plants with aerial roots include those of the tropical coastal swamp trees, e.

Most plants have roots growing at the bottom or basal of a plant body. When roots grow above the ground and elsewhere of the plant body they are referred to as adventitious root s. Aerial roots are an example of adventitious roots.

There are different types of aerial roots. The roots of strangler plants are those in which the aerial roots eventually strangle the plant of which they grow, e. Ficus sp. Pneumatophores are aerial roots specialized for gaseous exchange, e. Haustorial roots are those found in parasitic plants, e. Propagative roots are those that develop from the plant nodes such as those found in strawberry runners and sider plants.
