  1. Module 6 ReviewLife: Start Small…Think BIG!

  2. Lesson 6.01Organization of Life: Key Points: -The world is organized in a special way. -Living things are also organized according to a hierarchy (order from smallest to largest). Organization of Life: Atoms > Molecules > Cells > Tissues > Organs > Organ Systems > Organisms Question: What is the smallest level of organization?

  3. Lesson 6.02Cell Theory • Key Points: • -The cell theory was developed to show the relationship between cells and living things. • There are three parts to the cell theory: • All living organisms are made of cells. • All cells come from other cells. • Cells are the basic unit of life • -All living things are made of cells: unicellular or multicellular • -All cells come from other cells: All living things reproduce organisms that are the same. Cells divide by mitosis • Cells are the basic unit of life: All have the six properties of life: homeostasis, organization, metabolism, growth, adaptation, response to stimuli, and reproduction. • Question: How many parts make up the Cell Theory?

  4. Lesson 6.03Organelles • Key Points: • -The different parts of the cell are called organelles: Cell Membrane, Cell Wall, Chloroplast, Cytoplasm, Endoplasmic Reticulum, Golgi Apparatus, Mitochondria, Nucleus, and Vacuoles • -Animal cells differ from plant cells. • Plant cells contain some extra organelles that animals do not have: Cell Wall and Chloroplast. • Question: • Why don’t animals cells need a • Cell Wall or a Chloroplast? Animal Cell

  5. Lesson 6.04Cell Processes Maintain balance! • Key Points: • -Cells maintain a balance called homeostasis. • -The cell membrane is the ‘gatekeeper’ of the cell: controls what comes in and out of the cell. • -Cells extract energy from food for reproduction/ growth/homeostasis: ‘Mighty’ Mitochondria is the organelle that is responsible for this • -QUESTIONS: • How does the cell membrane help to maintain homeostasis for the cell? • Cells use energy for… • What is homeostasis? • What organelle within cells extracts energy from food? • Why is it important to maintain homeostasis?

  6. Lesson 6.05Human Body Systems Key Points: -There are several major system of the body: The Nervous System, The Circulatory System, The Respiratory System, The Immune System, The Digestive System, The Musculoskeletal System, and The Reproductive System. -The body systems MUST work together to properly function. Question: Which Human Body System breaks down food into energy?

  7. Lesson 6.06Infectious Agents Key Points: -There are many types of infectious agents that may infect humans. Bacteria : are single-celled living organisms because they exhibit the 6 properties of life (Homeostasis, Organization ,Metabolism , Growth, Adaptation, Response to Stimuli, and Reproduction) Viruses : are nonliving infectious agents. Viruses cannot reproduce or produce energy on their own. They must live inside a host cell. Viruses enter cells inside our bodies and use the cells to reproduce and produce energy. Fungi: are organisms that can cause infection. Some types of fungi are multicellular and some are unicellular. Some examples of fungi include: molds, mildews, yeast, and mushrooms. Parasites: are organisms that feed on other organisms for food. Some common examples of parasites are mosquitoes, ticks, and tapeworms. Question: Which Infectious Agent listed above is not alive?

  8. Lesson 6.07Classification • Key Points: • We put everything around us into groups: from general to specific! • Domain: Archaebacteria (bacteria that can live in extreme environments), Eubacteria (bacteria that live in and among us), and Eukaryote (plants, animals, fungus, and other simple organisms) • Kingdom • Phylum • Class • Order • Family • Genus • Species • Easy way to remember the order… • “King Philip Came Over for Great Spaghetti!” • Question: Which Classification Group above is the • most specific?

  9. Finished! REMEMBER… ALWAYS call your science teacher if you have any questions!
