• Tendril of a pea plant and phylloclade of Opuntia are analogous. 

• Wings of birds and limbs of lizards are analogous.

• Wings of birds and wings of bat are homologous.

Answer 1

Tendril of a pea plant and phylloclade of Opuntia are homologous. 

Explanation -  

The tendrils of a pea plant are leaflets modified into wire-like structures that help the plant cling to support and climb on it. Phylloclade of Opuntia is a green flattened stem with leaves modified into spines so as to reduce the loss of water by transpiration. Since both the plants, tendrils, and spines have a common origin but perform different functions. So, they are homologous structures.
