Essential Characteristics and Concepts of Living Organisms: A Midterm Review Guide

This midterm review focuses on the defining characteristics of living things, including reproduction, cellular composition, growth, environmental response, homeostasis, DNA, evolution, and energy needs. It explores atomic structure, differentiating between prokaryotes and eukaryotes, and the essential cellular processes like respiration. Review methods include practicing with past assessments, summarizing textbook chapters, quizzing peers, and vocabulary review to consolidate understanding. This comprehensive overview prepares students for exams and reinforces key biological concepts.

  3. Atoms and Electrons • How many subatomic particles make up an atom? • 3 • Protons are ______ • Positive • Electrons are ______ • Negative • Neutrons are ______ • Neutral

  4. What’s My Job? • Controls rates of reactions and regulates cell processes • Stores Genetic information • Used to store energy and is a part of cell membranes • Main source of energy • Carbohydrate • Lipid • Protein • Nucleic Acid

  5. Prokaryotes VS. Eukaryotes • Has a nucleus • Example – Animal and Plant cells • Larger and more complex (organelles) • Smaller • Example – Bacteria • Does not have a nucleus

  6. What am i? • Pick 3 parts of the ______ cell. • What are the jobs of those parts? • How did you know that this is a ______ cell?

  7. Respiration – Match Me! • Pyruvic Acid is broken down to CO2 • 1 Glucose is broken in half • Converts ADP to ATP • 2 types: lactic acid and alcoholic • Process that releases energy by breaking down sugars and releasing energy • Cell Respiration • Glycolysis • Fermentation • Krebs Cycle • Electron Transport

  8. What should I study? • Review your old tests and quizzes. Practice with them, if you got the answer wrong, look it up! • Read the e-textbook chapter summaries for Chapters 1, 2, 7, 8, 9! • Quiz a friend. • Review the vocab words.
