Levels of organization
- 4. Identifying the different levels of biological organization in an organism. Describing the parts that make up each level of organization and their functions. Describing how the parts that make up a level of organization affect the higher levels of organization and the entire organism.
- 6. CHARACTERISTICS OF LIFE 5 CHARACH- TERISTICS OF LIVING THINGS MADE UP OF CELLS RESPOND TO CHANGES` USE ENERGY GROW AND DEVELOP REPRO- DUCE
- 7. Life is organized into different levels based upon size (from small to large).
- 8. Organisms and Cells • Some organisms are unicellular. – This means they are made of only one cell. – Examples: bacteria, yeast • Some organisms are multicellular. – This means they are made of many cells. – Examples: humans, trees
- 9. Organisms and Cells • Unicellular organisms have nothing but a single cell. • However, multicellular organisms have many more levels of organization to make sure the whole body can work correctly, even when it is doing many things at the same time.
- 10. There are 5 Levels of Organization in Multicellular Organisms: • 1. Cells • 2. Tissues • 3. Organs • 4. Organ Systems • 5. Organisms
- 12. Atoms • are indivisible particles of matter • The smallest unit of matter that cannot be broken down into anything simpler by chemical means.
- 13. The smallest units of most compounds formed by the chemical bonding of atoms. Groups of the same or different kinds of atoms.
- 14. organelles Specialized structures that perform important cellular functions within cells.
- 15. The cell is the basic unit of life. Cells are specialized by size and shape for the job they do. The paramecium above is made of only one cell and it must perform all the jobs of the organism. Example: skin cell
- 16. T I S S U E S Tissues are made of the same type of cells grouped together to do a specific job. Example: Humans have four kinds of tissue in their Bodies: Epithelia, Muscle, Connective, and Nerve.
- 17. Organs Organs are made up of different tissues that work together to do a job. Example: a heart is an organ .
- 18. Organ Systems An organ system is a group of organs working together. Examples: •Human organ systems include circulatory, reproductive, digestive, nervous, respiratory. • Plant organ system-roots, stems, leaves= transport system.
- 19. Organisms All cells, tissues, organs and organ systems working together makes an organism. Example: a human
- 20. Population Groups of individuals of the same species that live in the same area.
- 21. Community Groups of different populations that live together in a defined area.
- 22. Ecosystem Groups of all the organisms that live in a particular place, together with their nonliving environment.
- 23. Biomes Groups of ecosystems that have the same climate and similar dominant communities Habitats of different kinds of plants and animals
- 24. Biosphere Part of the Earth in which life exists including land, water, air and atmosphere.
