1 CELL THEORY Study Guide KEY CONCEPT Cells are the basic unit of life. VOCABULARY cell theory cytoplasm organelle prokaryotic cell eukaryotic cell MAIN IDEA: Early studies led to the development of the cell theory. In a phrase, tell what each scientist, did to help develop the cell theory. Scientist Contribution to Cell Theory 1. Hooke 2. Leeuwenhoek 3. Schleiden 4. Schwann a E Virchow 6. What are the three parts of the cell theory? 7. Give two reasons ivhy the cell theory is important.. 8 Unit 2 Resource Book Study Guide 1 McDougal.Littell Biology
2 Name Period STUDY GUIDE, CONTINUED MAIN IDEA: Prokaryotic cells lack a nucleus and most Internal structures of eukaryotic cells. In the top left side of the Y shape below, write the characteristics of eukaryotic cells. In the top right side of the Y shape'below, write the characteristics of prokaryotic cells. At the bottom of the. Y shape below, write the characteristics that both, kinds of cells have in common. Then lightly cross out those characteristics at the top of the Y. Edkaryotic cells Prokaryotic cells C Vocabulary Check 8. What is cytoplasm? 9. Where do you find organdies? O C 2 C n a) 1. What statements summarize scientists' concepts of cells?

VOCABULARY cell membrane phospholipid fluid mosaic model selective permeability receptor MAIN IDEA: Cell membranes are composed of two phospholipid layers. 1. Draw a phospholipid in the box below. Label the three major parts. 2. Which part of a phospholipid is charged, or polar? 3. Which part of a phospholipid is nonpolar?. 4. What type of molecules interact with water, polar or nonpolar? 5. Where does a cell membrane come into contact with water? O. Why do the phospholipids surrounding the cell form a bilayer? ) E ) ) 8 A cell membrane has other types of molecules embedded in the phospholipid bilayer. List a function of each type of molecule in the table below.' Molecule 1. Cholesterol 8. Proteins 9. Carbohydrates Function Unit 2 Resource Book McDougal LitteII Biology Study.Guide 9
6 Name Period STUDY GUIDE, CONTINUED 1. In what way is a membrane fluid? 11. Draw a picture in the box below to represent selective permeability. MAIN IDEA: Chemical signals are transmitted across the cell membrane. 12. A detects a signal molecule and carries out an action in response. 13. A is a molecule that acts as a signal when it binds to a receptor. 14. A ligand that can cross the cell membrane can bind to an receptor A ligand that cannot, cross the cell membrane can send a message to a cell by binding to a receptor, which then shape Vocabulary Check 16. What is the fluid mosaic model? 17. The cell membrane allows some, but not all, molecules to cross. What term describes this pioperty? 1 Study Guide Unit 2 Resource Book McDougal Littell Biology
