Label the different parts of the animal cell

Label the different parts of the plant cell

1. If a cell contains 85% water and is placed into a environment which is 50% water. Is the CELL hypotonic or hypertonic? In which direction will the water move, into the cell or out of the cell? 2. A cell contains 85% water and is placed into a solution which contains 90% water. Is the SOLUTION in the environment hypotonic or hypertonic? In which direction will the water move? 3. A cell contains 95% water, the environment outside the cell contains 45% solutes. Is the cell in a hypotonic or hypertonic environment? 4. A cell containing 25% solutes is placed into a solution which contains 35% solutes. Which direction will the water move, into the cell or out of the cell? 5. A plant cell containing 95% water is placed into a 10% salt solution. Is the salt solution hypotonic or hypertonic? Which direction will the water move? Questions

Macromolecules 1)What are 4 macromolecules are we made up of? 2)Function of the 4 macromolecules

Carbohydrates-Short Term Energy Storage!! Lipids-Main Function = Energy Storage Proteins-Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormone, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood. Nucleic Acids-Stores genetic information Gene – specific piece of DNA that codes for a specific protein. Answers

DON’T FORGET

Monomers and Polymers Name the monomers and polymers for each Macromolecule: Carbohydrates: Proteins: Lipids: Nucleic Acids:

Carbohydrates: Monomer = Monosaccharides Polymer = Polysaccharides – many monosaccharides Proteins: – Monomer = Amino Acids – AA ’ s connected by peptide bond – Polymer = Many AA ’ s = Polypeptide = PROTEIN! Lipids: No polymers + No True monomer – Instead glycerol + fatty acid chains Nucleic Acids: Monomer = Nucleotides Polymer = DNA or RNA Answers

Water and Enzymes 1)5 properties of water 2)What does an enzyme do?

WATER PROPERTIES: 1. Cohesion 2. Adhesion 3. High Specific Heat 4. Less Dense as a Solid 5. Water is a terrific solvent ENZYME: Special type of protein (a catalyst) that speeds up chemical reactions by lowering activation energy Involved in most chemical reactions – Answers
