• A. It produces seeds but they are not enclosed in fruits.
• B. It has gametophyte and sporophyte which are independent of each other.
• C. It is a vascular cryptogam placed under class Lycopsida
• D. It shows protonema stage in its life cycle and doesn't bear true roots

Answer 1

Answer: (B)

The diagram given is of Equisetum. It is a pteridophyte which is placed under class Sphenopsida. It is a vascular cryptogam (having vascular tissue but not producing seeds). It has a haplo-diplontic life cycle in which the gameyophyte and sporophyte are independent of each other. Production of seeds without fruits is a characteristic of gymnosperms. Protonema stage and plant without true roots are seen mosses.
