Algae are photosynthetic plant organisms that do not have stems, leaves, roots, do not form seeds, flowers or fruits, such as higher plants. On the contrary, they have primitive organization, very simple in the lower taxonomic groups, more complex in the upper classes.


They form spores instead of seeds. Some have complex biological cycles (life cycles). They differ a lot from the Spermatophytes, both on land and sea, those most Greeks ignorant call "algae". And, of course, in Greek, the term is "algae" and not "algae" as they refer to some forms.


In terms of morphology there is an excellent variety. There are simple unicellular forms, colonial, microscopic, filamentous to complex, branched or not. Some look like tiny shrubs, with bunches of grapes, others look like leaves, net, pipes, etc.



There are algae miniature, invisible to the naked eye, such as those involved in phytoplankton, and are collectively called microalgae. Others are visible to the naked eye, what we see is called thalos, or even large dimensions that reach several meters in length, such as the big phaeophytes, collectively we call them macrophages.



Tiny are the Diatoms, the Pyrochriki (or the Dynofyki), several Chrysogyriki, a few Rodogirikis and some lesser known groups. A particular group is the prokaryotes of Cyanophyta (all algae groups belong to eukaryotic organisms), which are currently classified as photosynthetic bacteria and are called cyanobacteria, but are also referred to as Cyanobacteria, especially those used in nutrition and cosmetology. Representatives with larger dimensions are mainly Feiokriki and Rodiokriki and less Chlorrofki.


Below are the collections of algae grown in different Greek institutions. The purpose of this page is to update the available crops so that collaborations can be developed between the different institutions and the crop exchange.

If your crops are not on the list below, you can contact the person responsible.
