what would happen if a water plant is grown on land
A water plant is adapted to a life in water. It’s stem lacks the rigidity required by the land plants and hence cannot support the plant’s weight.
The plants have little or no roots which are so essential for the land plants. If a water plant is planted on land it would collapse dry out and then die.
