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 belong to the sub kingdom called Cryptogamae. They are seedless and flowerless plants. Their reproductive organs are very inconspicuous, and are therefore called as ‘cryptogams’, or ‘those with hidden reproductive organs’. They reproduce with the help of spores.
Example: Pinus
Gymnosperms and angiosperms belong to sub-kingdom called phanerogamae. These are the flowering plants with well-differentiated reproductive parts that produces seeds.
Example: Cycas
