2. How are living things organized ?

3. Organization of Living Things
molecules
organelles
tissues
organs
cells
organ systems
organisms

4. atoms - building blocks of matter, can not be broken down only rearrange
six most important for life are C, H, O, N, S, P
Atoms join to form molecules.

5. molecules
Lipids
Glucose
Protein
DNA
Water

6. organelles Organelles are the functional units of cells. chloroplast
mitochondria
nucleus
Golgi complex

7. cells
Cells have all the characteristics of life

8. tissues
tissues – a group of similar cells that perform a common function

9. organs
organs - composed of a number of tissues that work together to perform a specific task

10. organ system organ system found in complex multicellular organisms
a group of organs that cooperate in a series of related functions

11. organism

12. Biologist study organisms in large groups.
communities
populations
ecosystems
biomes
biosphere

13. populations
same species living in a particular place at a particular time
able to interbreed - mate within the population

14. communities
populations that live in the same area and interact (food, shelter)

15. ecosystem
community and its physical environment ex: forest, prairie, coral reef

16. biomes
large geographical area that has the same major forms of life that are identified by climate and vegetation
ex: tropical rain forest, grasslands, desert

17. Biosphere
includes all the life-supporting environments on the planet together with all the organisms that inhabit them
