Question

Chapter 3 Cells and Their Functions ESCRIBE METHODS BY WHICH SUBSTANCES ENTER AND LEAVE CELLS THAT REQUIRE CELLULAR ENERGY。 EXERCISE 3-7 Write the appropriate term in each blank from the list below exocytosis endocytosis active transport diffusion osmosis filtration pinocytosis 1. The process that utilizes a carrier to move materials across the plasma membrane against the concentration gradient using ATP 2. The movement of fluids through a membrane using a pressure gradient 3. The movement of water down its concentration gradient 4. The movement of a solute down its concentration gradient 5. The process by which a cell takes in large particles 6. The process by which materials are expelled from the cell Os MO using vesicles 7. Small fluid droplets are brought into the cell using this method

Answer 1

1. its Active transport as this is aginst the conc. gradient hence there is requirement of energy

2.its filtration for separation

3. its osmosis using the osmotic membrane

4.its diffusion with fick's law

5. its pinocytosis cell drinking

6. its exocytosis expulsion of material

7. endocytosis inside the cell entry
