Question

Bentham and Hooker's system of classification is based on
A. AP.de Candolle's system
B. England Pranti system
C. Eichler system
D. Wilkins system.

Answer 1

Hint:- George Bentham and Joseph Hooker were the two botanists of England. They proposed a taxonomic system for the seed plant known as Bentham and Hooker's system. Their classification of Genera plantarum comprises nearly 97,205 species which involves families of 202 plants and 7569 genera.

Complete step-by-step solution:-
Bentham and Hooker’s system of classification was done based on AP. De Candolle’s system. Ap.de Candolle was a botanist who proposed a Genus that involved 100s of plant families. Thus he created a classification system. AP.deCandolle’s classification is used in Bentham and Hooker’s classification system. Engler andPranti were two botanists from Germany. They proposed a classification system which includes there are 13 divisions in the kingdom plant, first 12 divisions comprises bacteria, fungi, algae, pteridophytes, and bryophytes. The last division was named Embryophyta Siphonogama. These were seeded plants. Embryophyta Siphonogama involved two subdivisions called Gymnosperms and Angiosperms. Eichler established a plant classification system in 1883. The system involves the division of the plant kingdom into the subdivision. These were named Cryptogams and Phanerogamae. Cryptogamae involved algae, Bryophyta, and pteridophytes and Phanerogams included Gymnosperms and Angiosperms. Wilkins modified Gartland classification which was based on fractures of the supracondylar humerus bone.
So the correct answer is option A. AP.de Candolle’s system.

Note:- Classification of the plant involves two groups. These are nonflowering plants and flowering plants. Nonflowering plants are divided into two groups, named spore-bearing and nacked seeds. Spore bearing plants are classified into mosses and ferns. Flowering plants have two groups, named monocot and Dicots.
