- 1. ORGANIZATION OF LIFE Chapter 1 Section 3 01-05-03 1
- 2. Objectives: List three advantages of being Multicellular. Describe the levels of organization in living things. 01-05-03 2
- 3. Cells: 01-05-03 3
- 4. Cells: • A cell is a membrane-covered structure that contains all of the materials necessary for life. 01-05-03 3
- 5. Cells: • A cell is a membrane-covered structure that contains all of the materials necessary for life. • Cells are only seen with a microscope. 01-05-03 3
- 6. Cells: • A cell is a membrane-covered structure that contains all of the materials necessary for life. • Cells are only seen with a microscope. • You have about 200 different kinds of cells in your body.(example: red blood cells, white blood cells, bacteria cells) 01-05-03 3
- 8. Tissue: Cells Working Together • A tissue is a group of cells that work together to perform a specific job in the body. 01-05-03 4
- 9. Tissue: Cells Working Together • A tissue is a group of cells that work together to perform a specific job in the body. • Blood, fat, and muscle cells are just a few of the many cells that make tissues in your body. 01-05-03 4
- 11. Organs: Tissues Working Together • Organ is two or more tissues working together to perform a specific job. 01-05-03 5
- 12. Organs: Tissues Working Together • Organ is two or more tissues working together to perform a specific job. • Examples include: stomach, intestines, heart, lungs, and skin 01-05-03 5
- 13. Organ Systems: Organs working together 01-05-03 6
- 14. Organ Systems: Organs working together • An organ system is a group of organs working together to perform particular jobs. (Examples: digestive system, nervous system, respiratory system) 01-05-03 6
- 15. Organ Systems: A Great Combination • The organs in an organ system depend on each other. If any part of the system fails, the whole system is affected. Failure of one organ system can affect other organ systems. 01-05-03 7
- 17. Organism: Independent Living • An organism is anything that can live on its own and is made up of at least one cell. 01-05-03 8
- 18. Organism: Independent Living • An organism is anything that can live on its own and is made up of at least one cell. • Example: Cat, Human, oak tree) 01-05-03 8
- 20. Types of Organisms: • Unicellular organism is a single cell that is living on its own. (Example: Bacteria) 01-05-03 9
- 21. Types of Organisms: • Unicellular organism is a single cell that is living on its own. (Example: Bacteria) • Multicellular organism can exist only as a group of cells and that can only survive when part of the whole organism. 01-05-03 9
- 22. Advantages of being Multicellular: 01-05-03 10
- 23. Advantages of being Multicellular: • Larger size means that there are fewer predators. 01-05-03 10
- 24. Advantages of being Multicellular: • Larger size means that there are fewer predators. • Longer life because the individuals life span is not limited to one cell’s existence. 01-05-03 10
- 25. Advantages of being Multicellular: • Larger size means that there are fewer predators. • Longer life because the individuals life span is not limited to one cell’s existence. • Specialization makes the organism more efficient. 01-05-03 10
- 26. Levels of Living Things: • Organism- one living individual 01-05-03 11
