1. 1 KEY CONCEPT CHAPTER HOME The cell is the basic unit of living things. CALIFORNIA Content Standards 7. 1. a Students know cells function similarly in all living organisms. 7. 1. f Students know that as multicellular organisms develop, their cells differentiate. VOCABULARY unicellular multicellular microscope cell theory bacteria CHAPTER RESOURCES SECTION OUTLINE

1. 1 CHAPTER HOME KEY CONCEPT The cell is the basic unit of living things. All living things are made up of one or more cells. Organisms share the following characteristics: • organization • ability to grow and develop • ability to respond • ability to reproduce VOCABULARY unicellular multicellular microscope cell theory bacteria Multicellular organisms include this frog and these water-lily plants. Many unicellular organisms live in pond water. CHAPTER RESOURCES SECTION OUTLINE

1. 2 KEY CONCEPT CHAPTER HOME Microscopes allow us to see inside the cell. CALIFORNIA Content Standards VOCABULARY cell membrane cytoplasm 7. 1. b Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls. nucleus 7. 1. c Students know the nucleus is the repository for genetic information in plant and animal cells. organelle 7. 1. d Students know that mitochondria liberate energy for the work that cells do and that chloroplasts capture sunlight energy for photosynthesis. eukaryotic cell prokaryotic cell wall chloroplast mitochondria CHAPTER RESOURCES SECTION OUTLINE

1. 2 CHAPTER HOME KEY CONCEPT Microscopes allow us to see inside the cell. A prokaryotic cell is relatively simple in structure, with no nucleus or other organelles. VOCABULARY cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle cell wall chloroplast SIMULATION View cells through different types of microscopes. A bacterium consists of a single prokaryotic cell. mitochondria CHAPTER RESOURCES SECTION OUTLINE

1. 2 CHAPTER HOME KEY CONCEPT Microscopes allow us to see inside the cell. A prokaryotic cell is relatively simple in structure, with no nucleus or other organelles. A eukaryotic cell is more complex, with many different organelles inside it. VOCABULARY cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle cell wall chloroplast mitochondria plant cell animal cell Plants and animals are made up of many eukaryotic cells. CHAPTER RESOURCES SECTION OUTLINE

1. 2 KEY CONCEPT CHAPTER HOME Microscopes allow us to see inside the cell. A prokaryotic cell is relatively simple in structure, with no nucleus or other organelles. A eukaryotic cell is more complex, with many different organelles inside it. VOCABULARY cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle SIMULATION Take a virtual tour of a cell wall chloroplast mitochondria CHAPTER RESOURCES SECTION OUTLINE

1. 3 KEY CONCEPT CHAPTER HOME Cells can perform specialized functions. CALIFORNIA Content Standards 7. 1. f Students know that as multicellular organisms develop, their cells differentiate. VOCABULARY specialization tissue organ 7. 5. a Students know plants and animals have levels of organization for structure and function, including cells, tissues, organ systems, and the whole organism. 7. 5. b Students know organ systems function because of the contributions of individual organs, tissues, and cells. The failure of any part can affect the entire system. CHAPTER RESOURCES SECTION OUTLINE

1. 3 CHAPTER HOME KEY CONCEPT Cells can perform specialized functions. • The single cell of a unicellular organism does all that is necessary for the organism to survive. • A multicellular organism is a community of specialized cells. • Scientific models make it easier to understand cells. VOCABULARY specialization tissue organ CHAPTER RESOURCES archaea The tarsier has many levels of organization in its body. SECTION OUTLINE

Characteristics of Life 2. Needs of Life B. All living things are made of cells. C. The microscope led to the discovery of cells. VOCABULARY unicellular multicellular microscope cell theory bacteria D. Cells come from other cells. E. The cell theory is important to the study of biology. 1. Louis Pasteur 2. The Source of Bacteria CHAPTER RESOURCES KEY CONCEPT SUMMARY

1. 2 KEY CONCEPT CHAPTER HOME Microscopes allow us to see inside the cell. II. Microscopes allow us to see inside the cell. A. The microscope is an important tool. VOCABULARY cell membrane cytoplasm B. Cells are diverse. nucleus C. Plants and animals have eukaryotic cells. eukaryotic cell 1. Structures That Process Information 2. Organelles That Provide Energy 3. Organelles That Process and Transport 4. Organelles for Storage, Recycling, and Waste prokaryotic cell organelle cell wall chloroplast mitochondria CHAPTER RESOURCES KEY CONCEPT SUMMARY

1. 3 KEY CONCEPT CHAPTER HOME Cells can perform specialized functions. III. Cells can perform specialized functions. A. Organisms can be classified by their cell type. 1. Archaea and Bacteria VOCABULARY specialization tissue organ 2. Eukarya B. Cells in multicellular organisms specialize. C. A multicellular organism is a community of cells. D. Scientists use models to study cells. CHAPTER RESOURCES KEY CONCEPT SUMMARY
