The first one is that transport proteins in the cell membrane ' Pick up ' molecules from outsides the cell and carry them in , while using energy in the process

The second method is that the the cell membrane surrounds a particle and takes it in

I hope that's help !

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
