1. Levels of Organization of Living Things

2. Apple In what level of organization does the apple belong?

3. Tree = Organism
Organisms are made of a group of what?

4. Flower Parts = Organ System
Organ systems are made of a group of what?

5. Parts of Tree = Organs
Roots
Leaves
Stems
Ovaries = Fruit!!!! Ah ha

6. Apple is an Organ The apple is the ripened ovary of the apple tree
Let’s keep going. The organ is made of what?

7. Plant Tissue
Tissues are made of a group of what?

8. Plant Cell
Cells are made of a group of what?

9. Fructose Molecule The Sugar in Fruit
Molecules are made up of a group of what?
Question: What atoms of elements do you see in the fructose ring structure?

10. Hierarchy of Organization
Biosphere
Ecosystems
Communities
Population
Organism
Organ system
Organ
Tissues
Cells
Organelles
Molecules
Elements or atoms

11. Let’s EAT!!! If you took a bite of an apple……. How would it taste?
What observations can you make about the apple?
Why would you eat an apple?

12. ENERGY We eat to get energy to live and THRIVE!!!!!!
What else do we eat?
Meat=Protein
Nuts= Fats or lipids
Fruits/veggies/bread= Carbohydrates
Biomolecules

13. 4 Biomolecules or Macromolecules
Carbohydrates
Proteins
Lipids or Fats
Nucleic Acids
Let’s Investigate Each Group

14. Carbohydrates This is a molecule of fructose or sugar from an apple.
Sugar is a carbohydrate.

15. Functions of Carbohydrates
1. Energy
2. Storage of energy
3. Structure
4. Packaging and lubrication

16. Proteins
Amino acids
Proteins

17. Proteins are the "workers" in the cell.
-Structural Proteins (hair, horns, etc.)
-Storage Proteins (albumin, casein)
-Transport Proteins (across membranes)
-Hormonal Proteins (insulin)
-Contractile Proteins (muscles)
-Antibodies
-Enzymes

18. Functions of Proteins

19. Lipids/Fats
Triglyceride
Phospholipids

20. Phospholipids are a major part of cell membranes

21. Functions of Lipids -Storage of energy -Cellular respiration
-Cell membranes
-Hormones
-Insulation
-Water proofing

22. Nucleotides Nucleotides are composted of 3 parts: Sugar Phosphate
Nitrogen base

23. Nucleotides Nucleic Acids

25. Functions of Nucleic Acids
Nucleic Acids (DNA & RNA)- Carry genetic information in the cell

26. Expression of proteins (traits)
