7. Science Thoughts 2/28
In one celled organisms, each cell supports the characteristics of life. How are plant and animal cells different from one celled organisms?
SPECIALIZATION

8. Notes Wednesday in class

9. Levels of organization
7.L.1.3 – Summarize the hierarchical organization of multicellular organisms from cell  tissue  organ  organ system  organism.
Levels of organization

10. Specialized To have a specific function. Example: A violinist.
Non-Example: One- man band.

11. Cell Smallest living thing
Examples: Muscle cells, Bone cells, Skin cells, Eye cells, Blood cells, Neurons (brain cells)
Non-Examples: Biceps, Triceps, Ear, Eye, Brain, Organelles

12. Tissue Group of cells working together to perform the same function.
Examples: Muscle, Blood, Fat, Cartilage, Epithelial
Non-Examples: Neurons, Muscle Cells, Femur

13. Organ Group of tissues working together to perform the same function.
Examples: Stomach, Lungs, Skin, Brain, Heart, Bones, Kidneys
Non-Examples: Muscle, Blood, Hair, Adipose, Cartilage

14. Organ System
Group of organs working together to perform the same function.
Examples: Digestive, Circulatory, Respiratory, Excretory, Nervous, Muscular, Skeletal.
Non-Examples: Heart, Lungs, Stomach, Bees, Trees, Kidneys

15. Organism Object that performs all life functions.
Examples: Humans, Plants, Mushrooms, Insects
Non-Examples: Rocks, Viruses, Fire
Locust, dragonfly, wood weevil

16. NOT highly specialized
If piece is broken off organism it will regenerate grow back!

17. Multicellular – Eukaryotic cells Plant – Animal - Fungus
Specialization – each cell in the organism has a different job
Single cell of multicellular organism CAN NOT survive on its own
Members of a community that work together to support organism

18. Cell – Tissue – Organ – Organ System - Organism
Science Thoughts 3/1
How are cells classified starting with individual cells and ending with organisms?
Cell – Tissue – Organ – Organ System - Organism

19. 51 - Organization of Multicellular 52 - Levels of Organization
Thursday in class
51 - Organization of Multicellular 52 - Levels of Organization

20. Science Thoughts 3/2
When is the Cells Unit Test and when is the Life Project due? Test: Friday, March 9 Project: Monday, March 12

21. 53 – Cells R Us Friday in class
The three domains and their cell types are: (prokaryotic) Bacteria, Archaea and Eukarya
Specialization is each cell having a different job
Levels of organization as a tree: cell: plant; organ: leaf; organ system: leaves, stems, roots
Difference between cell in unicellular and multicellular organism: unicellular does all tasks, multicellular does specialized tasks
Using Models:
similar to object represented: help to understand
Different from object represented: not fully accurate
