Expert Answer:

a) Cryptogams are plants whose reproductive organs are very inconspicuous. They include thallophytes (plants with ndifferentiated body), bryophytes (plants showing differentiated body but without vascular system) and pteridophytes (plants with well-differentiated body and well-developed vascular system). These plants do not bear seeds or flowers.
b) Phanerogams - These are plants with well-differentiated reproductive tissues that ultimately make seeds. The plant body is differentiated into root, stem and leaves. Also they possess well-developed vascular system. They include gymnosperms and angiosperms.
