What are respiratory roots? How do they differ from normal roots??
Hi Ravisha
Respiratory ROOTS
Floating roots e.g., Jussiea: In Jussiea which is an aquatic plant, special spongy roots called floating or respiratory roots arise from the plant. They are adventitious and enclose a tissue called aerenchyma. These roots usually develop above the level of water and serve to store up air and help in buoyancy of the plant. In addition, the floating roots may also perform the respiratory function. Hence, they are also called respiratory roots.
