What are Cryptogams?
Cryptogams are plants that reproduce through spores, without flowers or seeds. The name Cryptogamae (from Ancient Greek κρυπτός (kruptós) 'hidden', and γαμέω (gaméō) 'to marry') means \"hidden reproduction\", referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing plants.
Cryptogams include a variety of plant-like organisms, such as algae, fungi, lichens, mosses, liverworts, hornworts, and ferns. Some of these organisms are not considered as true plants in modern classification systems, but they are traditionally studied by botanists and have similar characteristics to plants, such as photosynthesis, cell walls, and multicellularity.
Cryptogams show a wide range of diversity in their morphology, ecology, and life cycles. Some cryptogams are unicellular or filamentous, while others have complex thallus-like or leafy bodies. Some cryptogams grow in aquatic or moist environments, while others can survive in dry or extreme conditions. Some cryptogams have simple alternation of generations, while others have more elaborate gametophyte and sporophyte stages.
What are Phanerogams?
Phanerogams are plants that reproduce through seeds, with or without flowers. The name Phanerogamae (from Ancient Greek φανερός (phanerós) 'visible') or Spermatophyta (from Ancient Greek σπέρματος (spérmatos) 'seed', and φυτόν (phutón) 'plant'), means \"visible reproduction\" or \"seed plants\", referring to the fact that seeds are produced, thus phanerogams represent the seed-bearing plants.
Phanerogams include two major groups of plants: gymnosperms and angiosperms. Gymnosperms are non-flowering plants with naked-seeds (seeds are not covered by a fruit), such as conifers, cycads, ginkgoes, and gnetophytes. Angiosperms are flowering plants that produce seeds covered by a fruit, such as grasses, herbs, shrubs, and trees. Angiosperms are the most prominent vegetation on earth.
Phanerogams also show a great diversity in their morphology, ecology, and life cycles. Some phanerogams are evergreen or deciduous, while others are annual or perennial. Some phanerogams have simple or compound leaves, while others have modified stems or roots. Some phanerogams have wind-pollinated or insect-pollinated flowers, while others have self-pollinated or cross-pollinated flowers. Some phanerogams have fleshy or dry fruits, while others have explosive or dispersal fruits.

What are the Examples of Cryptogams and Phanerogams?
There are many examples of cryptogams and phanerogams that can be found in nature or cultivated by humans. Here are some of the most common and interesting ones:
Cryptogams
Algae: Algae are aquatic or semi-aquatic organisms that can be unicellular or multicellular. They can be green, red, brown, or blue-green in color. They can produce oxygen and organic matter through photosynthesis. Some examples of algae are Chlamydomonas, Spirogyra, Ulva, Porphyra, Fucus, and Cyanobacteria.
Fungi: Fungi are heterotrophic organisms that feed on organic matter by secreting enzymes. They can be unicellular or multicellular. They can form hyphae, mycelia, spores, or fruiting bodies. Some examples of fungi are Yeast, Penicillium, Aspergillus, Mushrooms, and Lichens.
Lichens: Lichens are symbiotic associations between fungi and algae or cyanobacteria. They can grow on rocks, trees, soil, or other surfaces. They can have various shapes and colors. They can survive in harsh environments. Some examples of lichens are Cladonia, Usnea, Xanthoria, and Parmelia.
Mosses: Mosses are small plants that grow in moist and shady places. They have simple leaves and stems. They do not have roots but have rhizoids for anchorage. They reproduce by spores or gemmae. Some examples of mosses are Sphagnum, Polytrichum, Bryum, and Funaria.
