Which organ did Linnaeus primarily use to classify plants?

Answer and explanation

Correct answer: Stamens (Androecium)

Correct answer: B, the stamens or androecium. Linnaeus proposed a sexual system of plant classification. He mainly examined the number, arrangement, length and union of stamens, and also considered features of the pistils in forming his groups. Stamens were useful because their reproductive structures are often observable and provide comparatively stable characters for distinguishing flowering plants. A is wrong because leaf shape and arrangement can vary greatly with age and environment and were not the principal basis of Linnaeus's system. C is wrong because roots were not the chief organ used in his sexual system. D is wrong for the same reason: stem characters were not the central criterion. The word “sexual” here refers to reproductive structures, not to breeding experiments. Memory cue: Linnaeus's sexual system—count the stamens.
