Biology water is the most abundant molecule found in living organisms. most mammals, in fact, are approximately 70% water by weight. about two-thirds of this water is present inside cells. the other one-third is present outside cells (e.g., in blood plasma or other body fluids). why is water so important to cells? question 18 options: water is stored in cells to be used when the organism gets thirsty. almost all chemical reactions in life process occur in solutions with water. the main structural component found in plasma membranes and cell walls is water.

Solution concentration can be described in terms of tonicity. solutions are hypertonic, isotonic, or hypotonic to cells. a hypertonic is one that has a greater concentration of solute outside the cell and therefore a lower concentration. water will leave the cell, to the outside environment. this is one reason why organisms that live in fresh water cannot survive in salt water, the ocean. water will leave the organism’s cells and eventually the cells will undergo plasmolysis and the organisms will die. an isotonic solution is a balanced solution. that is, the solution concentration is balanced with the solution inside the cell. finally, when a cell is surrounded by a hypotonic solution, concentration of solute is greater inside the cell, concentration of water greater outside. water moves into the cell and the cell swells. if enough water enters, the cell can burst. on day 2, the egg was placed in 10% salt water. based on the student data, what type of solution would we label 10% salt water in this case? a) hypertonic b) hypotonic c) isotonic d) saline

Cindy conducts an experiment on diffusion using cells from the imaginary plant b. florensis. she notes that the cells are only made up of sugar and water and the cells contain a 5% sugar solution in them. however, the membranes are only permeable to water. she makes three solutions: pure water, 5% sugar solution and 10% sugar solution. in this experiment, she wishes to see if the solutions will change the mass of the cells in the plant. she places the cells in the solutions and after 20 minutes she makes individual slides of some of the cells from the three solutions, and she views them under a microscope.what is the dependent variable in this experiment?
