1. Organization of Living Things

2. Atom Makes up all living and nonliving things

3. Cell Basic unit of living things - 210 cell types muscle cell blood cell Muscle cell nerve cell hair cell stomach cell

4. Tissue Many cells performing a function - blood, muscle, bone

5. Organ Several tissues working together - heart, root, liver, leaves

6. Organ System Several organs working together; circulatory system, digestive system, etc.

7. Individual Organ systems working together! Snakes, maple tree, grasshopper

8. Population A group of individuals (school of fish)

9. Community All living things in an area

10. Ecosystem All living and non-living things in an area Prairie - grasses, hawk, snake, soil, etc.

11. Planet

12. Cell Basics * Theories on formation * Types of cells * Differences in cells

13. Cell Formation- Which Theory? A)Spontaneous Generation- the thought that living things can appear from nowhere- not true

14.  All living things are made of cells  All cells come from other cells  Cells are the most basic unit of LIFE Cell Theory

15. All Cells: Four Major Parts Cytoplasm Cell Membrane Genetic Material (DNA) Ribosomes bacteria animal cell

16. Two Types of Cells: A)Prokaryotic: simple cells with no nucleus (bacteria and archae) pro = before karyo = nucleus

17. Two Types of Cells: B) Eukaryotic: Larger cells with more organelles and a nucleus (plants, animals, fungus and protists) eu = true karyo = nucleus

18. Two Types of Eukaryotic Cells: Plant Cells: have a cell wall, central vacuole and chloroplasts

19. Two Types of Eukaryotic cells Animals Cells: have no cell wall or chloroplasts

20. Differences in cells Cells can be different sizes- bacteria v egg Cells can be different shapes- blood cell versus muscle cell
