Plant Taxonomy

Step 1: The role of Carolus Linnaeus in classification.
Carolus Linnaeus is considered the father of modern taxonomy and is best known for developing a systematic classification system for plants and animals. He proposed grouping organisms based on their reproductive organs, such as the number and arrangement of stamens and pistils in plants. This was a significant departure from earlier methods that were less focused on reproductive features.
Step 2: Comparison with other classification systems.
While Theophrastus and Michel Adanson also contributed to plant classification, their systems were not as detailed in terms of sexual characteristics. Linnaeus emphasized these characteristics for more precise grouping. John Hutchinson also worked on plant classification but did not specifically highlight sexual characteristics as Linnaeus did.
Step 3: Conclusion.
Therefore, the correct answer is (3) Carolus Linnaeus, who revolutionized the classification system by focusing on the basic numerical characteristics of sexual parts.
