11/6/1351st Day of School Learning 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 chart
Explain why I have written Euglena using the color scheme? How do the colors relate to how it gets energy? Do Now
All living things… • Are organized (cells, structures) • Reproduce (pass on genetic material) • Use energy • Grow& develop • Remove waste • Regulate Internal Conditions (homeostasis) • Respond to the environment • Evolve and Adapt What characteristics do all living things share? Characteristics of Life http://becklespinax.blogspot.com/
As you watch note what role each of the following plays in the life of unicellular organisms: • Nucleus • Flagella • Cilia • Pseudopod • Cytoplasm • Vacuole • Cell membrane • Mitochondria • Chloroplasts Life Functions of single-celled Organisms
On the BACK On the FRONT Definition: A cell is the basic unit of life that is able to perform basic life functions. Examples: Euglena: single-celled organism Red blood cell: cell in human body that carried oxygen Cell Cell 5. chloroplast Autotroph 6. flagella Photosynthesis 7. cilia Heterotroph 8. pseudopod 8 Vocabulary Flashcards
Organization: Single-celled, shapeless & has pseudopods • Respond to Environment: Cytoplasmic streaming allows it to move toward food or away from predators • Energy Use: Heterotrophic- engulfs food with pseudopods • Evolve/Adapt: Can become dormant Amoeba
Heterotroph (eats bacteria, algae & other protozoa • Surrounds food and engulfs it with pseudopods • Moves by cytoplasmic streaming • Can change shape • Waste is removed by the vacuole Amoeba Feeding & Waste removal
Asexual reproduction only • Through binary fission • One organism splits into two genetically identical organisms Amoeba Reproduction
Organization: Single-celled, shaped like a shoe sole & has cilia • Respond to Environment: Cilia allows it to move toward food or away from predators • Energy 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
Heterotroph (eats bacteria, algae & yeast) • Cilia sweeps food into oral groove • Moves by cilia • Has 2 nuclei: one large & one small • Waste is removed by the vacuole Paramecium Feeding & Waste removal
Asexual reproduction Through binary fission • One organism splits into two genetically identical organisms • Sexual reproduction occurs if there is environmental stress or overcrowding. Example of how paramecium response to the environment and evolve/adapt Paramecium Reproduction
