- CELL ENVIRONMENTS Fill in the following statement: Diffusion is the movement of molecules from_high_concentration to_low. concentration. is the diffusion of water. BEAKER #I The solution inside the beaker is: % water % salt The solution inside the cell is: 90 10 % water % salt 20% salt How will the water move? Into the cell or out of the cell? 10% salt How will the movement of water affect the cell? The cell O Water molecules This is a(n) solution.What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.PART D: CALCULATING THE ACTUAL SIZE OF A CELL. Once you know your microscope's diameter of the field of view, you can now calculate the actual size of your specimen. The ACTUAL SIZE of the specimen is the real size of the cell you are looking at. When you look at the cells through the microscope. the cells look very tiny. It is possible to determine the actual size of the cells you are looking at under LP.MP and HP. We will determine the actual size of a cell u I under HP. Step 1- Look at the cells under HP MAG. Step 2- Pick one cell you want to know the size of. Step 3- Imagine that this cell is placed along the left side of the field of view. (see example) Step 4-Estimate how many cels could fit across the field of view. Step 5- Record your answer Step 6- Use the formula below to calculate the actual size of your cell NOTE: Cells are very tiny therefore; the size of a cell is calculated in micrometers (um) and not mm. Cell size in (mm) ACTUAL SIZE OF CELL= HIGH POWERFOV.diameter of…
