Potato and Runners of Grass: Homologous Organs

Why are potato and runners of grass considered as homologous organs?

Are potato and runners of grass similar in structure and origin?

Answer:

Potato and runners of grass are homologous organs because they have a similar structure and origin. They both evolved from rhizomes, which are underground stems.

Homologous organs are organs that have similar structures but may have different functions. In the case of potato and runners of grass, they are considered homologous because they evolved from the same structure in their common ancestor.

Both potato and runners of grass originated from rhizomes, which are underground stems that allow for the storage of nutrients and propagation. Despite having different functions in different organisms, the similar structure and origin of potato and runners of grass indicate their homologous nature.

Homologous organs play an important role in understanding evolutionary relationships between different species. By studying homologous organs, scientists can trace back common ancestors and identify similarities and differences in organisms.
