Presentation Transcript

  1. Autotrophs Algae and plants in ecosystems

  2. “Are blue-green algae phytoplankton?” Phylogenetic Functional Functional: Plankton- freely floating , carried along by currents. Can be motile e.g. Rooted aquatic plants are not planktonic Microscopic algae can be planktonic, those that are comprise the PHYTOPLANKTON. Phytoplankton are important in reservoirs and in water column of large rivers.

  3. Periphyton- Microscopic algae growing on substrate (solid surface) Epiphytes- microscopic algae growing on macrophytes. Macrophytes- vascular (rooted) plants, mosses, liverworts, large colonial algal forms. Epilithon- layer of algae, bacteria, and mucilage covering substrate (rock surface).

  4. KINGDOM- PHYLA- CLASS- ORDER Procaryotes (bacteria)- Blue-green algae: a.k.a. cyanobacteria, cyanophytes Eucaryotes (with organelles) Planktonic and benthic phyla: Diatoms (Bacillariophyceae) Green algae a.k.a. chlorophytes, chlorophyceae example: Euglena sp. Planktonic phyla: Chrysophytes, Dinoflagellates, Cryptophytes

  5. Diatoms- have silica frustules Patterns of valves: Planktonic- centric (radial) Benthic- Trellisoid (Eunotia) Gonoid (angular) Pennate (around center line) Pennate diatoms have a RAPHE or PSEUDORAPHE:with raphe diatoms move by gliding on a mucilage trail Terms: Epitheca, Hypotheca, Valve, Connecting Band
