Which of the following are cryptogam?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Pteridophyta.
Cryptogams are plants that do not produce seeds or flowers and reproduce via spores. They include algae, bryophytes, and pteridophytes. Pteridophyta, such as ferns, have a well-developed vascular system but reproduce through spores, making them cryptogams.
In contrast, Gymnosperms, Dicots, and Angiosperms are phanerogams (seed-producing plants). Gymnosperms produce naked seeds, while angiosperms, including dicots, produce flowers and enclosed seeds. Thus, only Pteridophyta falls under cryptogams.
