Thallophyta, bryophyta and pteridophyta are called as ‘Cryptogams’. Gymnosperms and Angiosperms are called as ‘phanerogams’. Discuss why? Draw one example of Gymnosperm.

Thallophyta, bryophyta and pteridophyta have naked embryo that are called spores. The reproductive organs of these three groups are very inconspicuous or hidden, and they are therefore called ‘cryptogamae’. On the other hand, phanerogams (gymnosperms and angiosperms) have well differentiated reproductive organs and covered embryo having stored food.
