  1. Life Science Unit Overview: Chapter 1 – Structure of Living Things Lesson 1 – Cells Lesson 2 – From Cells to Organisms Lesson 3 – Diversity of Organisms Chapter 2 – Plant Structures and Functions Lesson 1 – Vascular Plants Lesson 2 – Plant Transport Systems Lesson 3 – Photosynthesis and Respiration Chapter 3 – Human Body Systems Lesson 1 – The Human Body Lesson 2 – The Digestive System Lesson 3 The Respiratory System Lesson 4 – The Circulatory System Lesson 5 – The Excretory System

  2. From Cells to Organisms Lesson Overview: 1) What do we already know? 2) Vocabulary 3) Drawings 4) Main Ideas 5) Review Structure of Living Things: Lesson 2

  3. Cells to Organisms: What do we already know? What do you know about plant and animal cells? Trillions of cells in your body Each has different organelles All cells have a nucleus How are plant and animal cells different or the same? Animal cells flex and plant cells are firm Plant cells have chloroplasts Do you think all animals have the same cells? I’m not sure Structure of Living Things: Lesson 2

  4. Cells: Vocabulary Part I Unicellular: Made up of only one cell Organism: An individual living thing Multicellular: Made up of more than one cell Tissue: A group of similar cells that work together to do the same jobs. Organ: A group of tissues that work together to perform a specific bodily function Structure of Living Things: Lesson 2

  5. Cells: Vocabulary Part II Organ System: A group of organs that work together to perform a specific bodily function Structure of Living Things: Lesson 2

  6. Cells to Organisms: Drawings(pg. 40) Structure of Living Things: Lesson 2

  7. Cells to Organisms: Main Ideas How are living things organized? (See drawing on previous slide) Quick Check -Compare and Contrast: What activities are common to all living things? All living things have cells, die, breath, grow, eat and excrete. Structure of Living Things: Lesson 2

  8. Cells to Organisms: Main Ideas 1) How do cells work together? They work together to perform the same task for the body. Tasks such as: The stomach digests food, The stem soaks up water. Quick Check -Compare and contrast: How do organs compare to organ systems? An organ system is made up of organs. Structure of Living Things: Lesson 2

  9. Cells to Organisms: Main Ideas What are some plant and animal organ systems? Plant: Root system and shoot system Animal: Digestive system Quick Check -Can an organ be part of two organ systems? Yes, the salamander's skin is a part of 2 systems. Structure of Living Things: Lesson 2

  10. Cells: Review Summarize the main ideas Think, Talk, and Write Structure of Living Things: Lesson 2
