Cell Transport Notes
 In a way a cell is like a miniature version of you. It requires nutrients
and, in the process of breaking down the nutrients, the cell produces
wastes. So there has to be a way to get nutrients in and wastes out.
This process in cells is called ______________________.
 The organelle responsible for cellular transport is the _______________
______________________.

Concentration gradient – The _________ distribution of particles.
Osmotic Pressure – the ______ pressure in cells
Turgor pressure – the water pressure in ________ cells
Plasmolysis – Process where the cell membrane _________
from the cell wall due to water loss.

Why are cells so small?
As the volume of a cell (the inside of the cell with all of the working
organelles) increases, the surface area (the cell membrane) doesn’t
increase as much. So…….
The cell membrane can’t diffuse enough nutrients in and wastes out
to maintain a larger volume, so cells have adapted by increasing the
surface area thus increasing the surface area to volume ratio.
Cell Transport Practice
Label each of the blood cells according to the type of solution that they
must have been placed into.
Label each of the solutions surround the cell as hypertonic, isotonic, or
hypotonic.
Give everyday examples of the following solutions compared to a human
body cell.
Hypertonic:____________________________________________________
Isotonic:_______________________________________________________
Hypotonic:_____________________________________________________
