- What would happen to an animal cell if you immersed it in a hypertonic solution for an extended period of time? Question options: Excess water is taken up by the central vacuole, causing the cell to swell, but not burst. The cell would shrivel and appear crenate. Nothing would happen, the system is in equilibrium. The cell would swell until it burst.Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings: A single-celled freshwater protist is placed into a beaker of salt water. A salt-water snail is mistakenly put into a freshwater tank. A head of lettuce is placed soaked in a sink of salt water. A bunch of carrots are placed soaked a sink of distilled water.Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings: A single-celled freshwater protist is placed into a beaker of salt water. A salt-water snail is mistakenly put into a freshwater tank. A head of lettuce is placed soaked in a sink of salt water. A carrot is soaked a sink of distilled, pure water.
- An animal cell has an internal concentration of 0.1M of NaCl. You place this cell into a solution with 5M NaCl. Select the true statement below. The solution is hypotonic to the cell therefore the cell will lyse The solution is hypotonic to the cell therefore the cell will shrivel The solution is hypertonic to the cell therefore water will lyse The solution is hypertonic to the cell therefore water will shrivelSuppose you have a cell from a freshwater fish that is isotonic with its surrounding environment, with a K+ concentration inside the cell of 0.05M. You then immerse this cell in saltwater where the K+ concentration is 0.25M. What would you predict will happen to the cell? a)Water will move into the cell, and the cell will swell and burst b)Water will move out of the cell, and the cell will shrink c)Water will move in and out of the cell with no net change in concentration, and the cell will remain the same size d)The cell wall will prevent the cell from changing sizeIf a percent difference is a negative number, what does this tell us about the change in weight of the artificial cell? If the percent difference is a negative number, what does this tell us about the movement of water across the membrane?
- The fluid mosaic model was first proposed by S.J. Singer and Grath L. Nicolson in 1972 to explain the structure of the plasma membrane. Discuss the structure of the different lipid molecules within the plasma membrane and relate it to their functions in the animal cell. You may choose any animal cell that you have learnt biologyDirections You are going to hypothetically place an animal cell in the following solutions shown in the table below. Your assignment is to represent what the cell and the solution look like when you first add the cell to the designated solution. Hypertonic, Hypotonic, or Isotonic Diagram Нуpertonic Нуpotonic Isotonic Please indicate which direction water would be expected to move, based on the solution, through the use of arrows ( t!). Use the following symbols to show the movement of molecules in your diagram: Water is to be represented by closed circles: Solute is to be represented by Xs: XWhat other cell ultrastructures do you expect to interact with the cell membrane?
- What is the difference between cell membrane and cell wall? What are the three main parts of a cell? Describe and give the main function of each.Draw to scale the outline of two spherical cells, one a bacterium with a diameter of 1 μm, the other an animal cell with a diameter of 15 μm. Calculate the volume, surface area, and surface-to-volume ratio for each cell. how would the latter ratio change if you included the internal membranes of the cell in the calculation of surface area (assume internal membranes have 15 times the area of the plasma membrane)? (the volume of a sphere is given by 4πr3/3 and its surface by 4πr2, where r is its radius.) discuss the following hypothesis: “internal membranes allowed bigger cells to evolve.”Examine the diagrams of the animal cell below. In each case, identify the cell as being in an isotonic solution, a hypertonic solution, or a hypotonic solution. Then write a caption in your own words for each cell to explain what is happening as a result of being in that solution.
