Statement 1 : Well aerating tissue aerenchyma is the most important anatomical feature of all hydrophytes. Statement 2 : Hydrophytes live in well aerated environment
1 Statement 1 is true, statement 2 is false.
2 Statement 1 and statement 2 are true.
3 Statement 1 and statement 2 are false.
4 Statement 1 is false, statement 2 is true.
Explanation:
Exp:A Aerenchyma is majorly found in aquatic and wetland plants. Aerenchyma is a modified parenchyma where the cells are arranged with regular air chambers in between to facilitate diffusion of gases in and out. Aerenchyma helps in buoyancy and respiration. It is characteristically found in aquatic floating plants. It is located in stems, hypocotyls, taproots, adventitious roots and root nodules under flooded conditions.
