Question

In Bentham and Hookers classification, the subclass Polypetalae and Gamopetalae have the cohorts in the ratio of:

• A. 1 : 1
• B. 2 : 1
• C. 2 : 3
• D. 3 : 2

Answer 1

The correct option is A 1 : 1

Bentham and Hookers have grouped advanced, seed-bearing plants into a major division called Phanerogamia. This division has been divided into three classes:

1. Dicotyledonae
   
2. Gymnospermae
3. Monocotyledonae

The class Dicotyledonae is further divided into sub-class as polypetalous, gamopetalous, and monochlamydae.

So, both polypetalous and gamopetalous have the same cohorts.

Thus, the correct answer is an option (A).
