2  prokaryotic autotrophic organisms  by infolding and strangulating from cytoplasmic membrane developed thylakoids  assimilation pigments:  chlorophyll and  beta-carotene  blue fyco-cyanine  red fyco-erytrine ALGAE

3  storage compound by algae: algetic starch  cells placed in a mucous sheath  monocellular algae:  evolutionary older  monocellular algae reproduce by division  after the division they stay together connected with mucus  fibrous algae:  evolutionary younger  developed sheath > cells placed after each other  fibrous algae reproduce by hormogonia ALGAE

4  genus Anabaena :  it has in-gapped heterocysts  > cells different in shape, able to bind air nitrogen  importance:  in rice fields they enrich the substratum with nitrogen substances ALGAE

5  cells have got:  pseudo-nucleus  circular DNA  synthesis of proteins proceeds in ribosomes  cytoplasmic membrane  thick cell wall > 4 layers  mucus casing  they have not got a flagellum ALGAE

6  photo-autotrophic organisms  photosynthesis like by green plants  chlorophyll and  source of electrons is the water > photolysis of water  a secondary product of photosynthesis is water  thylakoids lie loosely in the cytoplasm ALGAE

7  they can form calm spores – acinetes  they are formed through the connection of vegetative cells and thick cell wall ALGAE

8  they occurred 2.5 – 3.5 million years ago  they produced the oxygen in the atmosphere  they lived in colonies and created so called stromatolites:  mushroom shaped formations  they are formed through the sedimentation of calcium carbonate in the walls of algae  they have existed so far - Australia ALGAE

9  they grow:  in the water, wet soil, on the tree bark  omnipresent in all biotopes  symbiosis :  with lichens, liverworts, ferns, gymnospermous plants, orchids  they also live in hollow hairs of polar bears and sloths ALGAE

10  a distinctive geologic factor:  it participates in the production of rock travertine  it produces so called water bloom:  colony of algae Anabeana a Microcystis  gas bladders  plenty of organic substances > algae reproduce> the water decays > bad smell  they produce toxins > allergy ALGAE
