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. unicellular multicellular microscope cell theory bacteria CHAPTER RESOURCES SECTION OUTLINE

The cell is the basic unit of living things. 1.1 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: unicellular • organization multicellular • ability to grow and develop microscope • ability to respond cell theory • ability to reproduce Many unicellular organisms live in pond water. bacteria Multicellular organisms include this frog and these water-lily plants. CHAPTER RESOURCES SECTION OUTLINE

Microscopes allow us to see inside the cell. 1.2 Microscopes allow us to see inside the cell. CALIFORNIA Content Standards 7.1.b Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls. 7.1.c Students know the nucleus is the repository for genetic information in plant and animal cells. 7.1.d Students know that mitochondria liberate energy for the work that cells do and that chloroplasts capture sunlight energy for photosynthesis. cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle cell wall chloroplast mitochondria CHAPTER RESOURCES SECTION OUTLINE

Microscopes allow us to see inside the cell. 1.2 Microscopes allow us to see inside the cell. A prokaryotic cell is relatively simple in structure, with no nucleus or other organelles. cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle cell wall chloroplast SIMULATION View cells through different types of microscopes. mitochondria CHAPTER RESOURCES A bacterium consists of a single prokaryotic cell.

A eukaryotic cell is more complex, with many different organelles inside it. cell membrane cytoplasm nucleus eukaryotic cell prokaryotic cell organelle SIMULATION Take a virtual tour of a cell. cell wall chloroplast mitochondria CHAPTER RESOURCES SECTION OUTLINE

Cells can perform specialized functions. 1.3 Cells can perform specialized functions. CALIFORNIA Content Standards 7.1.f Students know that as multicellular organisms develop, their cells differentiate. 7.5.a Students know plants and animals have levels of organization for structure and function, including cells, tissues, organs, 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. specialization tissue organ CHAPTER RESOURCES SECTION OUTLINE

Cells can perform specialized functions. 1.3 Cells can perform specialized functions. • The single cell of a unicellular organism does all that is necessary for the organism to survive. specialization • A multicellular organism is a community of specialized cells. tissue organ • Scientific models make it easier to understand cells. archaea The tarsier has many levels of organization in its body.
