*COMPLETE SENTENCES!!! Chapter 7 Review Guide: Cells *** HIGHLIGHT YOUR ANSWERS!!! Part 1: Chapter Review Page 196, #1-10, Page 197-198 #14-16, 18, 22, 26, 28, 32. All in Complete sentences!!! Part 2: Review the following concepts and fill in the blanks as appropriate. DEFINITIONS: 1) Strong layer around the cell membrane in plants, algae, and some bacteria. 2) Large structure inside some cells that contains the cell’s genetic material (DNA) and controls the cell’s activities. 3) When the concentration is equal on both sides of a semi-permeable membrane, we say that the solution is _____________. 4) Cell organelle that releases energy from the stored food molecules 5) Stack of membrane in the cell in which enzymes attack carbohydrates and lipids to proteins; also responsible for sending proteins to their final destination. EUKARYOTE VS. PROKARYOTE: 6) If you are looking at a bunch of cells without a nucleus, what type of cell are you looking at? 7) Which type of cell can be multicellular? 8) Which of the following is an example of a prokaryotic cell? (Bacteria; muscle cell; an ant cell) 9) Name one example of a eukaryotic cell. ORANELLES: 10) The cell structure that assembles or makes proteins is a(n) 11) Which cell structure is responsible for photosynthesis? 12) When DNA twists and coils up so that it becomes visible, those visible structures are called _________. 13) Which cell structure is common to ALL cells? 14) Which cell structure assembles some components of the cell membrane and modifies some proteins? 15) The control center for the cell is the _________. 16) What is the outer boundary of an animal cell called? 17) The framework of the cell is the ________. 18) Membrane enclosed organelles which store water and salts are called ________. (Plants have large central structures of this variety, animals are smaller.) TRANSPORT ACROSS A CELL MEMBRANE: 19) Which type of transport across a cell membrane does NOT require energy? 20) The process where oxygen molecules pass from areas of higher concentration to areas of lower concentration is called ________. (Ex: from outside the fish gill to inside the fish gill cells.) 21) What is the name of the process where the molecules of water move across a membrane from areas of high water concentration to areas of low water concentration? 22) If a cell membrane is “semi-permeable.” What does this mean? 23) Draw the image below and explain what is happening to the movement of water and why. CELL SPECIALIZATION: 24) What does the term “cell specialization” mean? 25) TRUE or FALSE: Unicellular organisms, such as bacteria, have many levels of cell specialization. 26) Starting with “Cells,” write out the levels of organization. 27) List one example of an organ system.
