Remediation Packet for Biology Unit 2 cells Choose from one of the options and complete to prepare for the retest. Pick the option that you think helps you best to learn the material. You may choose more than one option. 1. Option 1 - Complete the Assignments on www.usatestprep.com for Cells. You must complete them all and take the cell benchmark. 2. Option 2 – Complete the Cell Unit from GA Virtual – you must complete the entire unit. http://cms.gavirtualschool.org/Shared/Science/BiologyI/Cells/index.html 3. Option 3 – Complete this packet Review all vocabulary for unit 1.

The best dense region in the nucleus where the assembly of ribosomes begins is called the a. nucleolus b. nuclear membrane c. chloroplast d. vacuole 38. The hollow tubes of protein that help maintain the shape of the cell are called a. microfilaments b. mitochondria c. microtubules d. ribosomes 39. Which organelles can use energy from sunlight to create energy-rich food molecules. a. lysosomes b. Golgi apparati c. vacuoles d. chloroplasts 40. What is the process by which material is taken into the cell by infoldings of the cell membrane? a. diffusion b. endocytosis c. osmosis d. exocytosis 41. The fourth and highest level of organization in a multicellular organism is a. cell specialization b. a tissue c. an organ system d. an organ On the lines provided, label the structures found in an animal cell that corresponds with the numbers in the diagram. 42 ______________________________ 43. ______________________________ 44. _______________________________ 45. _______________________________ Diffusion, Osmosis, Active and Passive Transport 46. The passage of large molecules through the cell membrane into the cell is called_____ a. endocytosis c. passive transport b. exocytosis d. osmosis 47. Active transport always requires ______________ a. water c. equilibrium b. energy d. osmosis 48. The movement of molecules from an area where there are many to where there are few is called a. diffusion b. equilibrium c. homeostasis d. osmosis 49. Particles tend to move from an area of high concentration to an area of low concentration in a process known as ___________________________ 50. When some substances can pass across them but others cannot, biological membranes are said to be ______________________________________ 51. The process in which water diffuses through a selectively permeable membrane is called __________________________________ 52. The process by which a protein channel allows molecules to cross the cell membrane is called facilitated diffusion On the lines provided, answer the following questions. 54. What are two functions of the cell membrane 1. ____________________________________________________ 2. ____________________________________________________ 55. What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion? ________________________________________________________________________________ ________________________________________________________________ 56. What is Osmosis? ______________________________________________________ 57. During the process of _________________________a molecule such as glucose must use energy to cross through a cell membrane. 58. For a molecule to move from an area of low concentration to high concentration, the process of _____________________________ must occur. On the lines provided, identify each diagram as showing an isotonic, a hypotonic, or a hypertonic solution inside the cell and describe how the concentration of water molecules will affect the shape of the cell(stay the same size, get bigger, or get smaller). 60. What is the difference between HYPOTONIC, HYPERTONIC, and ISOTONIC solutions? Create your own example (draw) of a hypertonic cell in a beaker.
