검증된 단계별 안내1
Step 1: Understand the defining characteristics of Kingdom Plantae. Organisms in this kingdom are multicellular, perform photosynthesis (autotrophic), and have cell walls made of cellulose.
Step 2: Analyze the first option: 'The organism is multicellular and ingests food for energy.' This describes a heterotrophic organism, which is more characteristic of Kingdom Animalia, not Plantae.
Step 3: Analyze the second option: 'The organism is multicellular, performs photosynthesis, and has cell walls made of cellulose.' This matches the defining characteristics of Kingdom Plantae, as it includes photosynthesis and cellulose-based cell walls.
Step 4: Analyze the third option: 'The organism is motile and has a chitinous exoskeleton.' This describes characteristics of Kingdom Animalia or Arthropoda, not Plantae.
Step 5: Analyze the fourth option: 'The organism is unicellular and lacks a nucleus.' This describes a prokaryotic organism, which would belong to domains like Bacteria or Archaea, not Kingdom Plantae.
