Question
We know that plants are harmed by excess water. But plants survive under flooded condition. How are they able to manage excess water?
Solution
Some varieties of rice are adapted to survive in the flooded condition also. These types of plants can show quick growth in their stem during floods and ensure that some foliage parts are always above the water. They have hollow stems which help in gaseous exchange and hence we can see some rice plant varieties survive even 1 month in the flood.
