Module 6 Review Life: Start Small…Think BIG!

Lesson 6.01 Organization 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?

Lesson 6.02 Cell 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?

Lesson 6.03 Organelles Key Points: Animal Cell -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

Lesson 6.04 Cell Processes Key Points: 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?

Lesson 6.05 Human 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?

Lesson 6.06 Infectious 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?

Lesson 6.07 Classification 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?

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