✯  homologous or analogous?

 thorns of citrus and tendrils of cucurbita are homologous organs.

✯ why are they homologous?

both of thorns and tendrils are stem modifications but their functions are not the same.

as,

✯ thorns: they give protection against predators and help to hold back the rate of evaporation.
✯ tendrils: they help to provide particular plant with support.


so, they are homologous.
