Question

Choose the incorrect statement on the natural system of classification:

• A. Plant Kingdom is divided into cryptogams and phanerogams
• B. Phanerogams are further divided into gymnosperms, dicotyledons and monocotyledons
• C. Cotyledons are the very first leaves that appear from a germinating seed
• D. Cryptogams are flowering plants and phanerogams are non-flowering plants

Answer 1

The correct option is D Cryptogams are flowering plants and phanerogams are non-flowering plants

Bentham and Hooker’s classification is an example of a natural system of classification. It considers the ultrastructure, anatomy, embryology and phytochemistry of the plants.
According to this classification, all the plants in the Plant Kingdom are broadly classified into cryptogams and phanerogams.
Cryptogams are non-flowering plants. They include algae or the thread like green substances in rivers, mosses on the rocks or the bunch of ferns next to the rivers.
Phanerogams are flowering plants and are further classified into gymnosperms and angiosperms. Gymnosperms are plants whose seeds are not enclosed by the fruit.
Angiosperms are plants whose seeds are enclosed in the fruits. They are of two types - Dicotyledonous (dicot) and monocotyledonous (monocot) plants.
Cotyledons are the very first leaves that appear from the germinating seed. Dicots have two seed leaves while monocots have one seed leaf.
