Step by step
Solved in 2 steps
- Why does water enter a cell that is placed in a hypotonic solution?In osmosis, water flows from hypertonic/hypotonic/isotonic solutions to hypertonic/hypotonic/isotonic solutions, until both solutions are hypertonic/hypotonic/isotonic.Which process requires energy—passive or active transport? Why is energy sometimes required to move solute across the cell membrane?
- How could membranes promote the movement of ions out of or into cells? How could membranes restrict the movement of ions out of or into cells?Distinguish between the following pairs of terms: a. diffusion; osmosis b. passive transport; active transport c. endocytosis; exocytosisIf 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?
