  1. The Diversity of Cellular Life Content Objectives: Explain cell specialization in multicellular organisms. Describe the levels of organization in multicellular organisms.

  2. What is the most numerous life form on our planet?

  3. What is the most numerous life form on our planet? Unicellular organisms dominate life on Earth.

  4. Unicellular Organisms • Unicellular organisms show all of the characteristics of living things.

  5. Multicellular Organisms Multicellular organisms come in may different forms.

  6. Multicellular Organisms have Specialized Cells! • cell specialization: the process in which cells develop in different ways to perform different tasks

  7. Levels of Organization cell  tissue  organ  organ system  organism Tissue:group of similar cells that perform a particular function Organ:group of tissues that work together to perform closely related functions Organ system: group of organs that work together to perform a specific function

  8. Lung Tissue – a group of lung cells One Lung Cell Lung Organs – a group of lung tissues Respiratory System – A group of organs Levels of Organization
