Question

Consider the following examples:

Which of the above examples form a pair of analogous organs?

• A. 1, 2 and 3
• B. 1 and 3
• C. 3 and 4
• D. 1 and 4

Answer 1

The correct option is C 3 and 4

Analogous organs have different origin but same function. Tendrils are threadlike appendage found in climbing plants. They grow in a spiral form winding around a host for support. Leaf tendril and stem tendril are a pair of analogous organs. Leaf tendril is a modification of leaf whereas stem tendril is modification of stem. Both these organs have different origins but perform similar function of clinging on to some support for growth.
