7. The Characteristics of Life
Cells – the smallest unit of organisms that carry on the functions life.
Made of one
or more cells –
unicellular
or multicellular

8. Displays Organization - cell, tissue, organ, organ system, organism

9. Growth – increase in size, adding cells and new structures Development – Natural changes that occur during growth

10. Reproduction – organisms produce new individuals

11. Responds to stimuli
Stimulus – anything that an organism responds to, either internal or external environment  Response – the reaction of an organism to a stimulus (critical to survival)

12. Requires energy - to fuel their life functions
Requires energy - to fuel their life functions. They get their energy from food or they use light energy to make their food  

13. Maintains Homeostasis – The regulation of an organism’s internal environment to maintain life.

19. Levels of Organization

20. Atom- Smallest object that retains the properties of an element Ex: Carbon, Hydrogen, Nitrogen
Atoms held together by a chemical bond makes up a Molecule

21. Molecules together will form organelles
And a group of organelles will make up a…..
cell

22. Multicellular Organization
Similar cells work together to form Tissues.
Lots of Muscle cells together… muscle tissue
Muscle Cell

23. Multicellular Organization
Different tissues work together to form organs.

24. Multicellular Organization
Different Organs work together to form organ Systems.
The heart is an organ made of cardiac muscle tissue… when the heart works with the arteries and veins it creates the circulatory system

25. Multicellular Organization
All the Organ Systems work together to form a living Organism.

26. A. Levels of Biological Organization
Organism – a living thing made up of one or more cells.
Unicellular – an organism composed of one cell, can carry on all the activities necessary for life
Multicellular – An organism composed of many cells, different cells carry out different jobs (division of labor),
