April 14 Some adaptations happen at cellular level Abiotic – (adj.) anything non-living, physical conditions that biotic organisms have to adapt to Cell Membrane Function - acts as a boundary layer to contain cytoplasm - selectively permeable - regulates movement of water, nutrients and waste Two types of organisms categorized by cell types Prokaryotic cells Eukaryotic cells 1) No Nucleus 1) Contain organelles 2) No organelles 2) DNA is linear, forming a number 3) Large, circular molecule of DNA 3) Chromosomes located in nucleus 4) All are unicellular organisms 4) Large, unicellular or milticellular 5) Include bacteria, cyanobacteria Cyanobacteria – photosynthetic, basis of many food webs Bacteria vs. everything else Plant cells have cell walls + chloroplasts Photosynthesis - Plants (algae) capture the sun’s energy and use it to make glucose some of which is converted into other organic compounds - Most other organisms use these molecules as a source of energy - Food web = tracing the path the energy from the sun travels Carbondioxide (CO2) + Water (H2O) – light cell food + 02 Chlorophyll Process of Photosynthesis 1) Solar energy is absorbed by photosynthetic pigments (chlorophyll)
