What is an organism? • Organisms are living things found in the environment made of cells • To be living, an organism must: Grow Take in Materials Release Energy Release Wastes Respond Reproduce
How do you classify organisms? • Organisms are grouped into a classification system called kingdoms Kingdom NameExample Kingdom Monera: Bacteria Kingdom Protista: Paramecium Kingdom Fungi: Molds Kingdom Plantae: Grasses Kingdom Animalia: Insects
What are organisms made of? • Organisms can be made of single (one) or multiple (many) cells • Most single-celled organisms are found in the Kingdom Monera and Protista • Most multi-celled organisms are found in the other Kingdoms Fungi, Plantae, and Animalia
Single-Celled Organisms • Tiny and Microscopic • One cell or unicellular, may have a nucleus or chloroplast or other cell structure • Can be of 3 types: Plant-like Animal-like Bacteria-like • Reproduction: Asexually or Sexually • Live: Alone or in Colonies • Movement: Some move, others do not
What do single-celled organisms look like? Plant-like Animal-like Bacteria-like
Multi-Celled Organisms • Many cells or multicellular, may have nucleus, chloroplast, and mitochondria • Can be of 3 types: Plant Animal Fungi • Reproduction: Asexually or Sexually • Live: Alone or in Groups • Movement: Can move, others cannot
This is my first attempt at an "Online Lesson". It is not meant to stand alone, but to be a support resource. Much of the information for this lesson came from my classroom multimedia presentation created with More. This lesson is also aligned to my classroom textbook Merrill Life Science - Chapter 9. The goal of this project is to produce a web site which supports students searching for information concerning the Kingdom of Protista.. • Kingdom Protista Characteristics • Members of this kingdom are often microscopic (unicellular) • Some protists can make their own food others cannot • Some protists display much movement others little. • Protista Classification • Most are microscopic, one-celled organisms. • Some form colonies of many cells • May have qualities of both animals and plants • Some make their own food through photosynthesis • Many have movement • Protozoans - "Animal-like" protista • Algae • All Those members of the protista kingdom which act like plants • Algaes are also found in the Moneran and Plant kingdoms • Possess more "Plant-like" characteristics • Other "algaes" are grouped with the monerans and others with plants. • Vary in color and often named by its color. • Most live in water, some on damp surfaces • Make up a large part of the plankton of the oceans • All algae contain chlorophyll and carry on photosynthesis What do multi-celled organisms look like? Plant Animal Fungi • Protozoans • Protozoans - "Animal-like" protista • All Those members of the protista kingdom which act like animals • Cannot make their own food • Most display a great deal of movement • Protozoans • Possess many "Animal-like" characteristics • Particularly movement • Some cannot make their own food • Many relationships from - free living, parasitic, saprophytic, mutualistic • Often classified by how they move • Amoeba - moves with Pseudopods (false feet) • Paramecium - moves with cilia • Flagellates - move like the Euglena flagellum • Sporozoans - produce spores • Amoeba - moves with Pseudopods
Single-celled One cell, unicellullar Can get food from other organisms or make their own food Reproduce asexually or sexually Live alone or in colonies Some move, others do not Multi-celled Many celled, multicellular Can get food from other organisms or make their own food Reproduce asexually or sexually Live alone or in groups Some move, others do not Comparing and Contrasting
