Characteristics of Living Things 5th Grade Science Basic Units of Life The Kingdoms of Life Organism Any Living Thing All living things are made of cells. Organisms carry out the basic functions of life: reproduce, get rid of waste, respond, grow and develop, and get or make own energy. Animal Cell Nucleus Mitochondrion Cell Membrane Cytoplasm Vacuole Plant Cell Difference: a cell wall and a cell membrane Contains chlorophyll which allows it to create its own energy from the sun. Plant cell under a microscope. Animal cell under a microscope. What are living things made of? Cells- Tiny living parts Tissues – Made up of cells working together Organs – Made up of groups of tissues working together Organ system- Made up of groups of organs working together Human muscle cell This is cardiac muscle cells. Where would you find cardiac muscle cells? Groups of tissue form organs The heart is a muscle that is important in moving blood throughout the body. Body Systems The circulatory system is made up of groups of organs which work together to do a specific job. Plant Kingdom Plants are broken up into two different groups: Vascular and Nonvascular Nonvascular Plants Plants without tubes. Live near a water source. Usually are not very tall. Vascular Plants Have tubes to carry nutrients from top to bottom. This allows some of these plants to grow extremely tall. Animal Kingdom Two Major phyla Vertebrates – Animals with backbones Invertebrates – Animals with out backbones. Chordata Animals with backbones are put into the phylum chordata. Invertebrates Animals without backbones tend to live in oceans and have soft bodies. Fungi Multi Celled organism Do not produce own food. Live off and decompose other organisms Examples – Yeast, Morels, MildewsMolds – Mushrooms, smuts, rusts Protists Most are one celled organisms Some are plant-like while others are more animal-like. Examples – Slime molds, Diatoms, Dinoflagellates, Green Algae, Euglenas Plant-like protists Euglena have the ability to create there own food because they contain chlorophyl. Bacteria Single Celled organisms No Nucleus Two types of bacteria Ancient Bacteria True Bacteria -Strep throat Some can be helpful, others can be harmful.
