Mr. Hall’s Biology Unit One Vocabulary On a separate sheet of paper to turn in, define the following vocabulary words. On the due date there will be a quiz where you will be allowed to use your definitions. About midway through the unit you will be tested on your knowledge of this vocabulary. 1. 2. 3. 4. 5. 6. 7. 8. amino acid carbohydrate macromolecule polymer monomer reactant product hypothesis 9. 10. 11. 12. 13. metabolism chitin control group dependent variable DNA (deoxyribonucleic acid) 14. enzyme 15. independent variable 16. 17. 18. 19. 20. 21. 22. 23. lipid nucleic acids nucleotide phospholipid bilayer proteins ribosome RNA (ribonucleic acid) scientific method To help you define the words and prepare for the Prefix, Suffix and Root Word Test, here are some root words, prefixes and suffixes used in Unit One. de- = without or remove (dehydration is the removal of water) di- = two (disaccharide: a sugar molecule consisting of two monosaccharides) hydr- = water (dehydrate: to remove water from) macro- = large (macromolecule: a giant molecule in a living organism formed by the joining of smaller molecules) -mer = part (monomer: a chemical subunit that serves as a building block of a polymer) mono- = single (monomer: a chemical subunit that serves as a building block of a polymer) poly- = many (polymer: a large molecule consisting of many monomers covalently joined together in a chain; polysaccharide: many monosaccharides joined together) -soma = a body (chromosome: the structure carrying the genetic material found in the nucleus of a eukaryotic cell) -vari- = change (variable: something that changes in an experiment)
