11/6/1351st Day of SchoolLearning goal (7.L.1): I will be able to describe the life characteristics of Amoeba and Paramecium.

Due Today: Euglena part of chart & flashcards

Evening Assignment: Finish Amoeba/Paramecium part of chartDo NowExplain why I have written Euglena using the color scheme? How do the colors relate to how it gets energy?

What characteristics do all living things share?All living thingsAre organized (cells, structures)Reproduce (pass on genetic material)Use energyGrow & developRemove waste Regulate Internal Conditions (homeostasis)Respond to the environmentEvolve and Adapt

8 Vocabulary FlashcardsCell

Cell 5. chloroplastAutotroph 6. flagellaPhotosynthesis 7. ciliaHeterotroph 8. pseudopodOn the FRONTDefinition: A cell is the basic unit of life that is able to perform basic life functions. Examples: Euglena: single-celled organismRed blood cell: cell in human body that carried oxygenOn the BACKAmoebaOrganization: Single-celled, shapeless & has pseudopodsRespond to Environment: Cytoplasmic streaming allows it to move toward food or away from predatorsEnergy Use: Heterotrophic- engulfs food with pseudopodsEvolve/Adapt: Can become dormant

Amoeba Feeding & Waste removal Heterotroph (eats bacteria, algae & other protozoaSurrounds food and engulfs it with pseudopodsMoves by cytoplasmic streamingCan change shapeWaste is removed by the vacuole

Amoeba ReproductionAsexual reproduction onlyThrough binary fissionOne organism splits into two genetically identical organisms

ParameciumOrganization: Single-celled, shaped like a shoe sole & has ciliaRespond to Environment: Cilia allows it to move toward food or away from predatorsEnergy Use: Heterotrophic- uses cilia to sweep food into the oral groove Evolve/Adapt: Stiff elastic membrane gives it shape and is covered in cilia that allow it to spiral through water

Paramecium Feeding & Waste removal Heterotroph (eats bacteria, algae & yeast)Cilia sweeps food into oral grooveMoves by ciliaHas 2 nuclei: one large & one smallWaste is removed by the vacuole

Paramecium ReproductionAsexual reproduction Through binary fissionOne organism splits into two genetically identical organisms

Sexual reproduction occurs if there is environmental stress or overcrowding.
