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