  1. The Diversity of Cellular Life Section 7–4

  2. Unicellular • A single-celled organism is also called a(an) organism. Unicellular

  3. Multicellular • What is cell specialization in a multicellular organism? It is the characteristic of having • separate tasks for each type of cell. Multicellular

  4. Multicellular Organisms • Cell specialization INCLUDES: • Specialized cells perform particular functions within the organism. • The human body contains many different cell types. • Some cells are specialized to enable movement.

  5. LEVELS OF ORGANIZATION • What are four levels of organization in a multicellular organism? • Tissues • Cells • Organs • Organ Systems Levels of Organization

  6. LEVELS OF ORGANIZATION • What is a tissue? It is a group of similar cells that perform a particular function. Levels of Organization

  7. LEVELS OF ORGANIZATION • What are the four main types of tissue in most animals? • Muscle • Epithelial • Connective • Nervous

  8. LEVELS OF ORGANIZATION • Groups of tissues that work together to perform a specific function are called a (an) • ORGAN

  9. LEVELS OF ORGANIZATION • What kinds of tissues can be found within a muscle in your body? • They include muscle tissue, nervous tissue, and connective tissue.

  10. LEVELS OF ORGANIZATION • What is an organ system? • It is a group of organs that work together to perform a specific function.

  11. CHLOROPLAST • An organelle that uses the energy from sunlight to make energy-rich food molecules

  12. ORGANELLE • A structure in eukaryotic cells that acts like a specialized organ

  13. VACUOLE • A saclike structure in which cells store materials

  14. CYTOSKELETON • A network of protein filaments that helps the cell maintain its shape

  15. EUKARYOTES • Cells that have a nucleus

  16. MITOCHONDRION • The organelle that uses energy from food to make high-energy compounds

  17. CELL THEORY • A theory that states that all living things are composed of cells

  18. OSMOSIS • The diffusion of water through a selectively permeable membrane

  19. ENDOCYTOSIS • The process of taking materials into the cell by means of in foldings of the cell membrane

  20. TISSUES • A group of similar cells that perform a particular function
