Tinospora has assimilatory roots and can perform photosynthesis.

Velamen tissue performs the function of absorbing atmospheric moisture.

Parasitic plants are able to absorb nutrient from the host due to the presence of Hustoria.

Sweet potato have reproductive roots, which serves as a mean of vegetative reproduction.

Mangrove plants have buttress roots and  prevent the tree from falling over (hence the name buttress) while also gathering more nutrients.

White spongy cigar-like floating roots remain in air and help the plant in floating. These are single adventitious roots, which also help in respiration.

Certain azospirillum species are symbiotically associated with cereal grasses.

The fungus protects the host plant from diseases.

Prop roots are an example of adventitious roots.

Roots are non-hygroscopic in nature.

Orchids have Clinging roots which help the plant to fix to the supporting host. Clinging roots arise from the node of a stem and pierce the stem and thus, help in fixing the plant to the supporting host.

Root pockets are vestigial root caps, not regenerated and found in aquatic plants because the roots of the plants that hang freely in water have no friction or resistance from the soil particles to overcome.

Prop roots provide Mechanical support to the plant. Prop roots arises from branches and on reaching ground they act as pillars, thus providing mechanical support to the plant
