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 peerPeer scores by writing their name in the selected block or initials next to checks they feelare not accurately placed.DO NOT RETURN POSTER – PUT RUBRIC, CHECK LIST, AND POSTER IN INBINTurn in Poster Self Assessment, check list rubrics do Copy HWWE DO WHILE PEER REVIEWING POSTER Listen to Review Cell Organelles through learning songhttps://www.youtube.com/watch?v=rABKB5aS2Zg Cell song
Week of February 18th through February 23th
Objective: To explore the

#2 What do you think you are made of?
#1 The chemical formula for water is H2O. 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.
3 Atom the smallest purest unit of matter
Molecule two or more atoms of the same or
different elements bonded

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 madeof molecules and compounds in cells.
are examples of nutrients
are the building blocks of proteins

STORE ENERGY FOR THE CELL AND OTHER JOBSDO 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 CELLTELLS . 1 TYPE IS DNA FOUND IN ALL CELLS. DNA TELLSCELLS WHICH MOLECULES TO MAKE SUCH AS PROTEINS.NUCLEOTIDE TELLS ORDER OF AMINO ACID AND BUILDSSPECIFIC 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.

Fat Lip – movie stars use steroids to get bigger lips-Wax is put on lips to prevent chappingPro Teens get A A so Proteins break down into smaller Amino AcidsPro positive so lots of repairing structure and regulatingbody processes

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

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
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 energyCarbohydrates-are sugars that are quick energyProteins-made of AA build, repair, & regulateNucleic Acids-carry information like DNAH2O in and out of cell
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.
5 Lipids – are fats that store energyCarbohydrates-are sugars that are quick energyProteins-made of AA build, repair, & regulateNucleic Acids-carry information like DNA
Refer to prior slide for question #11
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 aMolecule 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 membraneUses active transport which Requires energy in a process called osmosis to move water
Concentration in cellLower than out of cell So osmosis moves waterInto cell
Concentration in homeostasis Concentration in cellhigher than out of cell So osmosis moves waterOut of cell
Concentration in cellLower than out of cell LIKE IN SALTY ENVIRONMENTSo osmosis moves waterInto cell
