1. Select the correct statement (a) Tendril of a pea plant and phylloclade of Opuntia are homologous (b) Tendril of a pea plant and phylloclade of Opuntia are analogous (c) Wings of birds and limbs of lizards are analogous Wings of birds and wings of bats are homologous

• Soln:

The answer is (a) Tendril of a pea plant and phylloclade of Opuntia are homologous

Explanation:

Homologous structures share a common origin but may have evolved to perform similar or different functions. Tendrils in the pea plant are modified leaves that help in climbing, whereas the phylloclade of Opuntia is a flattened stem with leaves modified into spines to reduce transpiration. Since, tendrils and spines share the same origin, they are homologous structures.
