**Cellular Transport Assessment** **Fill in the Blank: 10 points** Complete each statement by filling in the blank with the best vocabulary term. Words may be used once, more than once, or not at all. **WORD BANK** Cells use their cell membrane to get the necessary nutrients in and the waste out. One main type of transport called 1.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ transport and it requires no energy. With transport that requires no energy molecules move from a high to a low 2.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ until 3.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ (balance) is reached. A type of passive transport that involves the diffusion of water is called 4.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. In a plant cell, the diffusion of water can increase or decrease the 5.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_pressure on the cell wall. A plant cell that is in a 6. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ environment would experience a high turgor pressor. If an animal cell is placed in an environment with a high concentration of solutes or a 7.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ environment, they could experience 8.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ and will shrivel up. Cells can take in larger molecules using 9.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_where large, [solid], particles are engulfed. Cells also use a similar process for taking in solutes or [liquid] called 10.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. These types of transport use a 11.\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ to transport the materials into the cell. **Matching: 10 points** \_\_\_1. PINOCYTOSIS A.

A B C Figure 1 PART A: (6 points) Sample C is the \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ solution and is causing \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ of The blood cells. Question 1 PART B: (2 points) The reaction of red blood cells to solutions with different concentrations is useful in medicine. Doctors use a test called the Osmotic Fragility Test to help them diagnose certain blood disorders in patients. The test measures the percentage of red blood cells that burst while being exposed to varying concentrations of a saline solution. A blood sample is taken from the patient and their red blood cells are then added to a series of solutions with concentrations ranging from 0.1%-0.9%. of NaCl. The results are then graphed. Based on what red blood cells do in hypertonic, hypotonic and isotonic solutions, which graph would you expect to see for red blood cells? **Circle One: (Graph A, Graph B, Graph C)** **GRAPH A** **GRAPH B** **GRAPH C** Critical Thinking Question 2: (1 point) What process is shown in the picture below? \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_  CRITICAL THINKING QUESTION 2: (2 points) *Label the following cell membrane parts that are important during cell transport using the following answer choices* A. protein channel B.
