Substances enter a cell through the cell membrane
What type of diffusion helps glucose enter the cell?
facilitated diffusion
Why is diffusion and osmosis important to the cell?
to allow nutrient to enter for sustaining the cell; or to prevent bugs to enter
Diffusion in cells?
when something can enter or exit the cell
How does pure water enter a cell?
through diffusion and osmosis. :-)
Which substance can enter a cell by diffusion without have to be digested?
water
What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
What process cause the water to enter or leave the cell?
the process that causes the water to enter and leave the cell is diffusion
Identify at least five ways by which a substance may enter the cell?
Osmosis, diffusion, facilitated diffusion, active transport, passive transport.
How would sugar enter a cell that has a low concentration of particles?
Diffusion
Describe how glucose molecules enter a cell by facilitated diffusion?
protein
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
