FACT: An organism's kingdom does not only describe physical characteristics. 

Organisms are classified into the different kingdoms based on physical appearance, their function, how they reproduce and how they obtain their food. 

EVIDENCE:
Kingdom Plantae: They obtain their food through photosynthesis
                              Reproduce asexually.
Kingdom Animalia : They obtain their food through hunting or consuming                                        other organisms.        
                              Reproduce sexually.

The kingdom of an organism  does not only describe physical characteristics. It is evident by that plant and animal kingdom are classified on the basis of photosynthetic ability.

Kingdom:
