Transport in cells

Transport in cells recap

​Cells need to move substances in and out of them.

Some of these substances are needed to keep the cell alive.

Some are waste products which need removing.

​On the next page there will be a link to BBC bitesize.
Take 5 minutes to recap:

1) What organelles are in an animal cell.
2) What is the function (job) of these organelles.

​Osmosis practical simulation

Reorder

Go to the "method" section on the simulation. Order the steps for method of this experiment.

• Cut the potates into cylinders the same size.

• Weigh your sample to get a first reading.

• Place your sample in the glucose solution.

• After a set time remove the sample from the solution.

• Weigh your sample again and calulate the change in mass.
