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

#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.

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

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.

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
