The Study of Living Things
Slideshow by Ms. Dickert

2. What does it mean to be “living?”
Living things are called ORGANISMS
MICROORGANISMS are tiny organisms
Living things carry out 5 BASIC LIFE FUNCTIONS
Living things are made from building blocks called CELLS
Living things are classified into 5 groups, called KINGDOMS

3. The 5 Life Functions Living things GROW
Living things use FOOD FOR ENERGY
Living things GET RID OF WASTES
Living things REPRODUCE
Living things REACT TO CHANGES

4. Which Life Function is Shown?

5. Cells Organisms are made from cells
Cells form tissues and organs that help the organism live
Cells contain different parts that do different jobs
Plant cells and animal cells are different in some ways

6. Cell Parts Cell wall for support (plants only)
Chloroplasts for food-making (plants only)
Cell membrane, which hold everything in
Cytoplasm, which fills the cell with a jelly-like substance
Vacuoles, which hold food, water, and wastes
Mitochondria, which power the cell
Nucleus, which controls the cell’s activities
Chromosomes, found inside the nucleus, which controls how the cell develops

7. Sample cells
Plant Cell
Animal cell

8. Levels of Living Things
CELLS are the smallest level
Cells make TISSUES (blood, bone, muscle, bark)
Tissues make ORGANS (heart, stomach, leaf)
Organs make ORGAN SYSTEMS (digestive system, circulatory system)
Organ systems make ORGANISMS (mouse, tree, dinosaur)

9. Classification of Living Things
Organisms are classified by TRAITS, or characteristics
The largest classification group is the KINGDOM
There are 5 Kingdoms (Plant, Animal, Fungus, Bacteria, Protists)
Kingdoms are further broken down into smaller groups
KINGDOM – PHYLUM – CLASS – ORDER – FAMILY – GENUS – SPECIES
An organism’s scientific name is based on the last 2 – genus and species
Classification gives us a common naming system
