Inquiring About the World of Life Biology is the science of life Traditionally divided into three divisions: - Botany - Zoology (NOT Zoo-ology!) - Microbiology 3 Modern Biology Many diverse subdivisions, such as: - Wildlife Biology - Cellular Biology - Anatomy & Physiology - Ecology - Genetics - Evolutionary Biology - Molecular Biology - Developmental Biology - Immunology - Behavioral Ecology - Marine Biology 4 - asking questions and seeking science-based answers The central activity of biology: scientific inquiry Biologists ask questions such as: how a single cell develops into an organism - how the human mind works - how living things interact in communities Biology is therefore a quest ? an ongoing inquiry about the nature of life

Chapter 7: Cell Structure & Function 7.1 Life is Cellular THINK ABOUT IT What?s the smallest part of any living thing that still counts as being ?alive?? Can we just keep dividing living things into smaller and smaller parts, or is there a point at which what?s left is no longer alive? As you will see, there is such a limit. The smallest living unit of any organism is the cell. 7.1 Student Objectives: I can state the cell theory and distinguish between prokaryotes and eukaryotes. I can describe how the different types of microscopes work. Bellringer 7.1 ? Cell Theory Cell Theory

Chap 32 pp. 618-626. pp. 635 Hand washing Toronto, ON: Elsevier. Evolve Nursing Skills Online ? Infection Control Module- Lesson 1 & 2 In your own words answer the following questions. Explain the chain of infection and how it is related to the transmission of infection. The chain of infection is: Infectious agent, Reservoir, Portal of exit from reservoir, Mode of transportation, Portal of entry, susceptible host. Infection develops in chain stays intact and connected. Following infection prevention and control practices will break the chain and likely prevent infections from developing.

Photosynthesis Plants use sun to make glucose Photosynthesisers are base of food chain Too much algae? You got problems Need water Sunlight Nutrients Fertilizer runs into water, increases nutrients, too much algae Too much fish food/waste also does this Dead zone - an area in ocean or lace with scant or little oxygen Increased nutrients Increased algae growth Increased O2 from algae photosynthesis during day At night, respiration decreases O2 Uses up nutrients and die Decomposing bacteria consume/decompose algae Bacteria then blooms Oxygen is decreased even further Anoxic conditions - marine life cannot be supported Organic must have carbon AND hydrogen Chloroplasts - organelles consisting of photosynthetic pigments, enzymes, and other molecules grouped together in membranes

Prokaryotes- An organism of the kingdom Monera (or Prokaryotae), comprising the bacteria and cyanobacteria; characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles, and by DNA that is not organized into chromosomes. Spontaneous generation- mistaken idea that life can arise from nonliving materials Biogenesis- Idea that living organisms come only from other living organisms. Protocell- Large, ordered structure, enclosed by a membrane, that carries out some life activities, such as growth and division. Archaebacteria- Chemosynthetic prokaryotes that live in harsh environments, such as deep-sea vents and hot springs The Origin of Life Origins: The Early Ideas Spontaneous generation The idea that nonliving material can produce life

Chapter 1 Inquiring About the World of Life: Evolution: fundamental organizing principle of bio Biology: scientific study of life Answer questions about our everyday lives Evolution is core of bio New properties exist at each level of biology Emergent properties: arise at each level that do not exist at the preceding level Systems Biology: goal is to model the dynamic behavior of bio systems Organisms interact with environment Structure and Function Correlate at all levels Cells are basic units of structure and function Eukaryotic cell: subdivided into internal membranes Prokaryotic cell: simpler and smaller than eukaryotic cell Life based on information in form of DNA Genes: units that transmit inheritance info Genome: ?library of genetic instructions an organism inherits?

ECOSYSTEMS: COMPONENTS, ENERGY FLOW & MATTER CYCLING CHAPTER 4 ECOLOGY Study of the relationships between organisms and their environment How organisms interact with their nonliving environment such as sunlight, temperature, moisture, nutrients, etc. KEY WORK IS: INTERACT - Connections in Nature What is an organism? What make up organisms? Organisms are either: EUCARYOTIC - SURROUNDED BY A MEMBRANE HAVE A DISTINCT NUCLEUS HAVE INTERNAL ORGANELLES All organisms except bacteria. PROCARYOTIC - SURROUNDED BY A MEMBRANE NO DISTINCT NUCLEUS NO INTERNAL PARTS SURROUNDED BY MEMBRANES Bacteria What is a SPECIES? How do species differ? What is the difference between sexual and asexual reproduction? Number of species on earth is not known 5 million to 100 million maybe

Viruses, Prokaryotes, Protists, and Fungus Study Guide Discovery of Viruses : ? While studying the tobacco mosaic disease that affects tobacco plants, scientist Dmitri Ivanovsky passed extracts of diseased tobacco leaves through filter pores small enough to strain out bacteria ( which was thought of as being pathogens) ? After realizing that the strained substance (thought to be disease free) could STILL pass on the disease, it lead him to believe that the pathogen was NOT bacteria?but what was it? Structure of Viruses : ? Basic viral structure includes genetic material (either DNA or RNA ? not both) surrounded by a protein called capsid. ? In some viruses, the capsid is surrounded by a lipid envelope that surface from which

Chapter 2 Science, Systems, Matter, and Energy Chapter Overview Questions What is science, and what do scientists do? What are major components and behaviors of complex systems? What are the basic forms of matter, and what makes matter useful as a resource? What types of changes can matter undergo and what scientific law governs matter? Chapter Overview Questions (cont?d) What are the major forms of energy, and what makes energy useful as a resource? What are two scientific laws governing changes of energy from one form to another? How are the scientific laws governing changes of matter and energy from one form to another related to resource use, environmental degradation and sustainability? Updates Online
