1. Characteristics of Living Things

2. What is Biology?
Biology  the study of living things
Bio = Life
ology = study of
Living things are classified into 5 groups:
Animals
Plants
Fungi
Protists
Bacteria
In Biology, we call these the 5 kingdoms of living things.

3. Living vs. Nonliving Living things Biotic Called organisms
Made up of CELLS
(unicellular and multicellular)
Examples:
Plants
Animals
people
Non-living things
Abiotic
“A” = no; not
Examples:
Soil
Rocks
Water
Air

4. Synthesis How organisms build necessary molecules Examples:
Protein Synthesis: making proteins from DNA
Photosynthesis: plants make food using energy from sunlight

5. Transport How organisms get what they need to cells Examples:
Circulation and absorption
Active transport; diffusion; osmosis; facilitated diffusion

6. Excretion
How organisms get rid of their waste and balance their fluids
Examples:
Removing fluids to balance water
Removing unused molecules from food

7. Sweating – reduces body temperature
Regulation
How organisms control body processes
Examples:
Important to homeostasis- to maintain balance within the body
Short term change based on stimulus (stimulus and response)
allows living things to adapt to changes
Sweating – reduces body temperature

8. Nutrition How organisms break down and absorb food Examples:
Fungi decompose dead remains (decomposer)
Plants make their own food (autotroph)
Animals consume other organisms and absorb food (heterotroph)

9. Grow & Develop
How organisms make new cells and develop necessary body parts
Examples:
Birds develop in an egg
Mammals develop in a uterus
Fungi develop from a spore
Plants develop from a seed
Grow – to get larger in size; body size
Develop – to change due to hormonal or mental cues

10. Living things are complex and made up of many levels
5. Organism
4. Organ System
3. Organs
2. Tissues
Cells – basic unit of life
* Atoms, Molecules
*Elements

11. Muscle cell
Muscle tissue
Heart
Circulatory System/ Organsim

12. Reproduction How organisms make new individuals like themselves
Examples:
Prevents Extinction
Sexual vs. Asexual
Internal or external fertilization

13. Respiration
How organisms get oxygen and release carbon dioxide to make usable energy
A series of chemical reactions that result in the release of energy (ATP)
Examples:
Anaerobic respiration = no oxygen
Aerobic respiration = oxygen
Plants exchange gasses
