1. Monday- YOU DO COPY HW U1L3 and learn cell song..take the quiz, take a screen shot of your screen with the score and include the time on your computer in the screen shot, You may use your phone for a picture if I can see the time and score. You must show me during homeroom or at shuttle so not to take up class time. I DO Explain peer scoring of poster You Exchange your poster with a peer Peer scores by writing their name in the selected block or initials next to checks they feel are not accurately placed. DO NOT RETURN POSTER – PUT RUBRIC, CHECK LIST, AND POSTER IN INBIN Turn in Poster Self Assessment, check list rubrics do Copy HW WE DO WHILE PEER REVIEWING POSTER Listen to Review Cell Organelles through learning song https://www.youtube.com/watch?v=rABKB5aS2Zghttps://www.youtube.com/watch?v=rABKB5aS2Zg Cell song

6. #2 What do you think you are made of? #1 The chemical formula for water is H 2 O. The H stands for Hydrogen and the O stands for oxygen. If you do not get enough water you will dehydrate, have organ failure, and then expire.

7. 3 Atom the smallest purest unit of matter Molecule two or more atoms of the same or different elements bonded Compounds must have different elements C The element/atom Carbon C 2 Two or more atoms of C make a molecule NOT A COMPOUND C 2 H 4 Different atoms bonded are compounds and molecules Atom the smallest purest unit of matter Molecule two or more atoms of the same or different elements bonded Compounds must have different elements bonded O The element/atom oxygen O 2 Two or more atoms of O make a molecule NOT A COMPOUND H 2 O Different atoms bonded are compounds and molecules CO 2 CO H2H2 H2H2 N2N2 N2N2 C 6 H 12 O 6 H H C C https://www.youtube.com/watch?v=R1R MV5qhwyE 5:52 What is an atom – Basic for Kids https://www.youtube.com/watch?v=R1R MV5qhwyE 5:52 What is an atom – Basic for Kids

10. Is the element that makes up most of the human body Gold if it is 100% Au atoms is a pure element, but the human body is made of molecules and compounds in cells. Gold if it is 100% Au atoms is a pure element, but the human body is made of molecules and compounds in cells.

11. are examples of nutrients are the building blocks of proteins NOTES ON NEXT SLIDES NEEDED FOR INCREASED DOK

12. STORE ENERGY FOR THE CELL AND OTHER JOBS DO NOT MIX WITH WATER MOLECULE CONTAINS SUGAR, STRACH, OR FIBER. SIMPLE CARBS = 1 OR A FEW SUGARS COMPLEX CARBS=MANY SUGAR or Starches FAT MOLECULE OR SIMILAR, SUCH AS WAXES AND STERIODS. USED AS A SOURCE OF ENERGY AND FOR ENERGY STORAGE MOLECULES THAT CARRY INFORMATION IN THE CELL TELLS. 1 TYPE IS DNA FOUND IN ALL CELLS. DNA TELLS CELLS WHICH MOLECULES TO MAKE SUCH AS PROTEINS. NUCLEOTIDE TELLS ORDER OF AMINO ACID AND BUILDS SPECIFIC PROTEIN MADE OF SMALLER NUCLEOTIDES MADE OF SMALLER AMINO ACIDS PROTEINS BREAK DOWN INTO THE SMALLER AMINO ACIDS WHICH THEN REGROUP TO MAKE NEW PROTEINS WHICH BUILD AND REPAIR BODY STRUCTURES AND REGULATE BODY PROCESSES. ENZYMES ARE PROTEINS THAT CATALYZE OR SPEED UP REACTIONS.

13. Memory Strategies Fat Lip – movie stars use steroids to get bigger lips- Wax is put on lips to prevent chapping Pro Teens get A A so Proteins break down into smaller Amino Acids Pro positive so lots of repairing structure and regulating body processes https://www.youtube.com/watch?v=eB793h16R8Ahttps://www.youtube.com/watch?v=eB793h16R8A Lipids I’ve got Lipids Song https://www.youtube.com/watch?v=eB793h16R8Ahttps://www.youtube.com/watch?v=eB793h16R8A Lipids I’ve got Lipids Song https://www.youtube.com/watch?v=DipuIBLJ3nghttps://www.youtube.com/watch?v=DipuIBLJ3ng The Protein Song https://www.youtube.com/watch?v=DipuIBLJ3nghttps://www.youtube.com/watch?v=DipuIBLJ3ng The Protein Song Pro Teens get A A so Proteins break down into smaller Amino Acids Pro positive so lots of repairing structure and regulating body processes

14. Memory Strategies NAPs Nucleotide – tells the order of amino acids Amino acids-builder of other molecules such as Proteins-used to build, repair, regulate Car for speedy energy https://www.youtube.com/watch?v=l1RsfMMY1vghttps://www.youtube.com/watch?v=l1RsfMMY1vg Carbohydrates yours song https://www.youtube.com/watch?v=H8TKm-fdEl8https://www.youtube.com/watch?v=H8TKm-fdEl8 3:09 Carbohydrate song cch

15. Phospholipid Bi-Layer- Head is hydrophilic Hydrophilic – ATTRACTED to water Head is outer part of cell membrane Tail is hydrophobic Hydrophobic – REPELS water tail points inward Phospholipid Bi-Layer- Head is hydrophilic Hydrophilic – ATTRACTED to water Head is outer part of cell membrane Tail is hydrophobic Hydrophobic – REPELS water tail points inward Bi layer 1 side Bi layer 2 nd side Hydrophobic REPEL WATER Hydrophilic ATTRACTED TO WATER 11 PICTURE USED TO EXPLAIN HOW PHOSPHOLIPIDS FORM A BARRIER BETWEEN WATER IN THE CELL AND WATER OUT OF THE CELL

16. Hydrophobic REPEL WATER Hydrophilic head ATTRACTED TO WATER Hydrophilic head ATTRACTED TO WATER Hydrophobic tail REPELS WATER Hydrophobic tail REPELS WATER OUTSIDE OF CELL WATER INSIDE OF CELL WATER

17. Hydrophobic REPEL WATER HEAD Hydrophilic ATTRACTED TO WATER contains negatively charge phosphate group Glycerol TAIL Hydrophobic tail REPELS WATER 2 long fatty acid hydrocarbon chains INSIDE OF CELL WATER

18. Hydrophobic REPEL WATER IN THE CELL TOO MUCH WATER SO TAILS WILL REPEL MORE WATER OUT OF THE CELL TOO MUCH WATER IS N THE CELL SO AS THE HEADS ATTRACT TO WATER BUT THE TAILS WILL REPEL THE WATER PREVENTING WATER FROM ENTERING THE CELL. FURTHER PROTECTION OFFERED BY BILAYERING. TWO SETS OF LIPID TAILS REPEL THE WATER

19. EXPLAIN IN YOUR NOTEBOOKS HOW THE BI-PHOSPHOLIPID LAYER OF THE CELL MEMBRANE WOULD HELP RESTORE HOMEOSTASIS T0 THE CELLS?

20. Hydrophilic head ATTRACTED TO WATER Hydrophobic tail REPELS WATER Hydrophilic Head ATTRACTED TO WATER 12 14 A PLUG ON A BECAUSE WHEN IT IS IN THE WATER STAYS IN THE TUB BUT WHEN IT IS OUT THE WATER GOES OUT OF THE TUB, MORE WATER CAN BE ADDED TO KEEP A HOMEOSTASIS EVEN FLOW AND IF TOO MUCH IS ADDED THERE IS A DRAIN HOLE TO LET IT OUT UNDER THE SPICKET

21. Make up the phospholipid bi layer of the cell membrane If looked at individually C and H make up the tail of the phospholipid layer 17 Lipids – are fats that store energy Carbohydrates-are sugars that are quick energy Proteins-made of AA build, repair, & regulate Nucleic Acids-carry information like DNA 17 Lipids – are fats that store energy Carbohydrates-are sugars that are quick energy Proteins-made of AA build, repair, & regulate Nucleic Acids-carry information like DNA H 2 O in and out of cell

22. Smallest unit one atom of a pure substances is an element 2 or more atoms of the same or different elements bonded An atom is a pure substances (an element). Two or more atoms are a Molecule. An atom is a pure substances (an element). Two or more atoms are a Molecule. 5 Lipids – are fats that store energy Carbohydrates-are sugars that are quick energy Proteins-made of AA build, repair, & regulate Nucleic Acids-carry information like DNA 5 Lipids – are fats that store energy Carbohydrates-are sugars that are quick energy Proteins-made of AA build, repair, & regulate Nucleic Acids-carry information like DNA Refer to prior slide for question #11

23. 7 and 8 An atom can only be one element, An atom is pure. The picture has two Different types of atoms so it is a Molecule and a compound. 7 and 8 An atom can only be one element, An atom is pure. The picture has two Different types of atoms so it is a Molecule and a compound. Water is 2/3 of the mass of the cell. Water moves in and out of the cell via the bi phospholipid cell membrane Uses active transport which Requires energy in a process called osmosis to move water Water is 2/3 of the mass of the cell. Water moves in and out of the cell via the bi phospholipid cell membrane Uses active transport which Requires energy in a process called osmosis to move water

24. Concentration in cell Lower than out of cell So osmosis moves water Into cell Concentration in cell Lower than out of cell So osmosis moves water Into cell Concentration in homeostasis Concentration in cell higher than out of cell So osmosis moves water Out of cell Concentration in cell higher than out of cell So osmosis moves water Out of cell Concentration in cell Lower than out of cell LIKE IN SALTY ENVIRONMENT So osmosis moves water Into cell Concentration in cell Lower than out of cell LIKE IN SALTY ENVIRONMENT So osmosis moves water Into cell
