Answer 2

Answer:

Corolla of pea plant

Explanation:

Fabaceae or Papilionaceae is a large and economically important family of flowering plants. It includes trees, annual or perennial herbaceous plants and shrubs. In Papilionaceae, the petals are 5 - outermost posterior petal is large which is known as the vexillum or standard, two lateral petals are known as the wings or alae, and the two anterior and innermost petals are united to form a boat-shaped structure known as the keel or carina. Hence, the correct arrangement of the corolla is 1+2+(2).
