• B. The leaves are thin
• C. The leaves are long
• D. The roots are poorly developed

Answer 1

Answer: (A), (D)

The correct options are
A

The leaves have a bulbous stem below each leaf

D

The roots are poorly developed

The leaves of Eichornia are thick, waxy, rounded, and glossy. The primary adaptation of Eichornia is its hollow bulbous stem below each leaf. These allow the plants to float, keeping the leaves and flowers above the water so they don't rot. The roots are poorly developed because they are surrounded by water. Thin and long leaves are usually adaptations of submerged plants like Vallisneria.
