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.

Select the correct pair.
1 Loose parenchyma cells rupturing the epidermis and forming a lens shaped opening in bark - Spongy parenchyma
2 Large colorless empty cells in the epidermis of grass leaves - Subsidiary c
3 In dicot leaves, vascular bundles are surrounded by large thick-walled cells - Conjunctive tissue
4 Cells of medullary rays that form part of cambial ring - Interfascicular cambium
Explanation:
Exp:D When the cells of medullary rays differentiated. They give rise to the new cambium called interfascicular cambium. Medullary rays \(\longrightarrow\) Interfascicular Cambium Secondary growth in dicot 5 tem - Complementary cells are loose parenchyma cells rupturing the epidermis and forming a lens shaped opening in bark. - Large colorless empty cells in the epidermis of grass leaves are called bulliform cells. - In dicot leaves vascular bundles are surrounded by large thick walled cells called sheath cells.
