    Study Notes

    The Microscope and Cells

    • Robert Hooke used a microscope to observe cork cells
    • Cells are the fundamental units of all living organisms
    • Cells from different plants and animals vary in shape and structure
    • Differences in cells are due to their specific functions
    • Cells work together to form tissues and organs
    • Tissues and organs perform specific tasks in organisms

    Plant Cells

    • All plants are composed of cells
    • Plant cells, like other cells, are responsible for protecting the organism, obtaining nutrients, and other vital functions
    • Plant cells contain chemical elements
    • Unicellular organisms, such as bacteria (see Fig. 6.2), are composed of a single cell
    • Multicellular organisms, such as many plants and animals, are composed of multiple cells
