(N/A) Thallophyta,Bryophyta,and Pteridophyta are classified as 'Cryptogams' because their reproductive organs are inconspicuous or hidden,and they do not produce seeds.
On the other hand,'Phanerogams' include Gymnosperms and Angiosperms. These plants possess well-differentiated reproductive tissues and produce seeds. In these plants,the embryo develops into a seed,which contains stored food for future growth.
An example of a Gymnosperm is $Pinus$ (Pine),which is a coniferous tree that produces seeds in cones.
