Pteridophytes may be homosporous or heterospoers, while all gymnosperms are heterosporous. The flowers of angiosperms have male and female reproductive parts. Answer: Similarities of gymnosperm with cryptogams are that they both have similar basic parts and structure of the plants and both are similar in structure with an exception of the flowers Explanation: Similarities of gymnosperm with cryptogams :- Gymnosperms :- Gymnosperms are produced from naked seeds and are non-flowering plants. They are practically adapted to various environmental conditions, like high mountains, desert, water, land, etc. 1.Monocots Thallophytes, bryophytes and, pteridophytes are included in 'cryptogams', whereas gymnosperms and angiosperms are 'phanerogams'.

Angiosperms are flowering plants, evolving from gymnosperms during the Mesoz, which include about 85-90% of all living plant species. Fertilization is siphonogamatic (with the help of pollen tube) in both groups. Angiosperms adapted to a challenging terrestrial ecosystem by developing a complex vascular system, flowers and fruit. The ovules of Gymnosperms are borne directly on the surface of the megasporophyl. The word angiosperm originated from Angion, which means hidden, and Sperma, which means seed.
