BIOLOGY: The Study of Organisms Bios = life ology = study of Characteristics Of Living Things Composed of cells The smallest component of life. Unicellular = 1 cell Multicellular= many cells All multicellular organisms have differentiated cells, that each have specialized functions. Reproduction Genetic Code – directions for inheritance (DNA) Sexual = DNA from 2 different parents Asexual = single parent (cloning, budding) Growth and Development These processes allow organisms to mature and gain the ability to reproduce. Controlled by DNA and RNA. Use Energy Important for metabolism, all of the chemical reactions in the body Animals eat to obtain energy Plants photosynthesize Response to environment Stimulus = a signal Response = a reaction Internal Balance Homeostasis – maintaining constant internal conditions (sameness) Evolution - species change over time Branches of Biology Zoology = animals Paleontology = ancient life Cytology = cells Botany = plants Entomology = insects Microbiology = Ecology = Anthropology = Levels of Organization Molecule Cell Tissue Organ Organ Systems Organisms Population Community Ecosystem Biosphere CHECK FOR UNDERSTANDING 1. List the characteristics of life. 2. The smallest unit of life is the ___________ 3. All living things must be able to ____________________, or to make more of their own kind. 4. All living things have a _____________________, which are like instructions for building the body 5. During development, some cells become liver cells, some become skin cells and some become muscle cells. This process is called ________________________ 6. Animals get their _______________ by consuming food. Plants get it by __________________________________ 7. __________________________ is the maintaining of an internal balance, or sameness. 8. ______________________ is the process where species change over time.
