  1. Androecium structure

  2. Flower arrangements

  3. Leaf morphology

  4. Plant habit

Show answer
Correct Option: A
Explanation:
  • Carolus Linnaeus is considered as the 'Father of Taxonomy'. He developed a way to name and organize species. 
  • Linnaeus’s artificial system of classification was based on the androecium structure. The significance of flower and fruit structures was first recognized by him. He emphasized the basic numerical characteristics of sexual parts i.e., stamens and carpels. Thus the Linnaeus system is also known as a sexual system.

So the answer is 'Androecium structure'.
