Gnetopsida-eg: Gnetum They are found throughout much of the earth, but form dominant vegetation in many colder and arctic regions. There is a regular heteromorphic alternation of generations. a plant that reproduces by spores, without They are less evolved plants. In the two great groups of seed plants, gymnosperms and angiosperms, the sporophyte is the dominant phase in the life cycle, as it is also in the vascular cryptogams; the gametophytes are microscopic parasites on the sporophytes. A cryptogam (scientific name Cryptogamae) is a plant that reproduces by spores, without flowers or seeds. E.g.

The term cryptogams (kruptos= hidden, gamos= wedded) was suggested by Linnaeus in 1754 for all non-flowering plants that reproduce by means of spores and do not produce seeds. Pteridophytes have evolved xylem and phloem for the first time. Leaves decurrent and the twigs with roughened by peg-like projections that persist after leaves fall. The species is also widely used in the ethnomedicinal trade. Q.3: What are Phanerogams in biology?Ans: Phanerogamspossess special structures for reproduction and generate seeds. are not enclosed in an ovary. Phanerogams - Flowering and seed-bearing plants. Gymnosperms had become the dominant vegetation on Earth before the rapid diversification of angiosperms. Diversity in Living Organisms Class 9 Extra Questions Science Chapter 7 Gametophyte is completely dependent on sporophyte and they are physically connected. All the following differentiate gymnosperms from the higher cryptogams except: (1) Presence of an independent green gametophyte (2) development of an ovule . What are the characters Mendel selected for his experiments on pea plant? "Cryptogamae" means hidden reproduction, referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing plants. It does not store any personal data.

There are no vessels anatomically in both pteridophytes (except Selaginella, Marsilea) and gymnosperms (except Gnetales). Are found naturally in areas of relatively moist climates where water stresses are minimal. 10: These series of micrographs shows male and female gymnosperm gametophytes.

Gymnosperm vs. Angiosperm: Similarities Gymnosperms and angiosperms are more highly evolved than nonvascular plants. The key difference between angiosperms and gymnosperms is how their seeds are developed. Majority of Gymnosperms are trees. Heterospory has never resulted in dioeciousness in the sporophyte in pteridophytes, while it is so in many gymnosperms. Pteridophytes are mostly herbs or shrubs. Reproduction By spores. Wind carries pollen from male to female cones. Vascular bundles are conjoined, collateral and open. Difference Between Cryptogams and Phanerogams They lack true roots, stem or leaves. The generative cell in pollen splits into two sperm cells.
