Phanerogams and Cryptogams
(Greek (phanerós) 'visible', (gaméō) 'to marry' ), so visible reproduction and have seed
Phanerogams, plants with visible sex organs, 52 families proposed by Michael Adamson, 1727-1806, France
Phanerogams are now called spermatophytes, for plants that produce seeds, i.e. the seed plants.
Cryptogams
A plant or plant-like organism that reproduces by spores, without flowers or seeds.
(Greek (kruptós) 'hidden', (gaméō) 'to marry' ), so hidden reproduction and no seed
Cryptogams include algae, lichens, mosses, and ferns

Phycobilins
Phycobilin, C33H38N4O6, phycocyanobilin, a propanoic acid.
Phycobilins enable red algae to live photosynthetically in deep water.
Phycobilin pigments occur in the cytoplasm and stroma of chloroplasts, where they absorb light energy that is passed on to other processes.
The metal-free blue phycobilin pigment in a conjugated chromoprotein of blue-green algae, which functions as light-absorbing substance together with chlorophylls.
1. Phycocyanin is a blue-green pigment in Phylum Cyanobacteria, pigment-protein complex, fluorescent, an accessory pigment to chlorophyll.
It occurs in Spirulina Platensis.
2. Phycoerythrin (PE) is a red protein-pigment complex, in red algae, Division Rhodophytan, fluorescent, an accessory pigment to chlorophyll.
Phycobiliproteins
Phycobiliproteins are water soluble fluorescent proteins derived from cyanobacteria and marine algae.
Phycobiliproteins, in nitrogen-fixing cyanobacteria, occurs in cyanobacteria and red algae are composed of water-soluble phycobilin pigments and protein.
Nitrogen-fixing cyanobacteria, e.g. Anabaena azollae, live symbiotically within leaf cavities of the water fern Azolla.
The genus Azolla is an important source of nitrogen fertilizer for the rice industry in Vietnam, China and the Philippines.
Nitrogen-fixing cyanobacteria, e.g. Anabaena azollae, lives symbiotically within leaf cavities of the water fern Azolla.
Azolla, floating fern
Phytochromes
Red light sensitive phytochromes are phycobilin-protein pigments involved in floral induction.
They are activated by the length of day, hours of darkness, red light, with peak response 660 nm.
