Use the following "clues" and "word bank" provided below to complete your water crossword puzzle. Use your "pen tool" or "A" tool to type a letter in each box. Across3. Transportation of water and nutrients in plants against the force of gravity.4. Substances that have a pH more than 75. Bond between oxygen and hydrogen of a water molecule6. Water is _, as it has a slight positive charge.8. Bond between oxygen of one water molecule and hydrogen of another water molecule9. Water molecules sticking to each other forming a water droplet10. cohesion and adhesion working together allowing paper clips to float on water.11. Substances that have a pH 7Down1. Substances that have a pH less than 72. Waters ability to stick to many substances and dissolve them.7. Water molecules sticking to other stuffWORD BANKPolar; Surface Tension; Cohesion; Adhesion; Capillary Action; acid; base; neutral; Polar Covalent Bond; Hydrogen Bond; Universal Solvent Water being a polar substance, dissolves _ substances. Only polar substances Only non-polar substances It dissolves all substances Sort the following as "organic" vs "inorganic" Organic Carbohydrates Lipids Proteins Inorganic Water Macromolecules Fill in the blank by clicking on each square and choosing the correct word(s). Macromolecule Monomer Function Example Carbohydrate Monomer: monosaccharide Function: short-term energy Examples: bread, pasta fruits Lipid Monomer: glycerol + fatty acids Function: long-term energy source insulation Examples: butter and oil Nucleic Acid Monomer: nucleotide Function: store and transfer genetic information Examples: DNA and RNA Protein Monomer: amino acid Function: build muscle Examples: meat and beans Which of the following are carbohydrates? monosaccharides disaccharides polysaccharides All of the above Which molecule is a carbohydrate? C8H39O3 C8H19O8N19 C10H40O4N3P2 C30H60O30 Matching Pairs Match the molecule with its appropriate pairing. Cellulose makes up cell wall Sucrose table sugar Glucose sugar made in photosynthesis and used in respiration Fructose sugar in fruit and honey Starch long term energy storage in plants Glycogen Energy storage i animals; stored in the liver Steroid lipid which controls signals in the body Insulin controls blood sugar levels Hemoglobin carries Oxygen in the blood Decide if each of these belongs with Carbohydrates or Lipids. Carbohydrates C6H12O6 Short term energy Monosaccharide Starch Glucose Fructose Glycogen Cellulose Iodine turns blue-black Benedicts turns orange with heat Sucrose Fruits, breads, honey, oatmeal 1 Carbon: 2 Hydrogen: 1 Oxygen Lipids Steroid Long term energy storage in animals Phospholipid bilayer cell membrane Provide insulation for animals in cold climates Glycerol and Fatty Acid Paper bag becomes translucent Fats, oils, and waxes Hydrophobic Decide if each of these belongs with Proteins or Nuclei Acids. Proteins Amino Acids C, H, O, N only Eggs, meat, beans and nuts Biurets indicator turns purple Peptide bonds Hemoglobin Insulin Enzymes Nucleic Acids Store and transmit genetic information C, H, O, N, P Nucleotides DNA RNA Instructions for proteins Phosphate, sugar, and a base
