Question : Differentiate between homologous and analogous organs by giving plant example. |
|
Answer» Solution :Homologous organs are those whose STRUCTURE and origin is same but functionally they differ. They exhibit divergent evolution. e.gu, In PLANTS the thorns of bougainvillea and tendrils of cucurbita exhibit homology. Analogous organs are those whose structure and origin is not similar but functionally, they are same. They exhibit convergent evolution. e.g., peepal plant LEAVES and Opunitia STEM, both of them performing PHOTOSYNTHESIS but are different in origin. |
