Cyanide is a poison which is called the respiratory inhibitor as it doesn’t let mitochondria perform the aerobic respiration.This in turn badly affects the energy availability in the cells which causes the active transport to either slow down or stop.Passive transport takes place in the cells by the process of diffusion or osmosis.

The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’.

Control the volume of solution used for each strip.

A 20 page pack of worksheets that have been produced for use in Key Stage 4.These ions are then moved to xylem vessels and eventually the leaves where chlorophyll production takes place.Hence, we can say that active transport is critical in both plants and animal cell and also in both the examples the cell contained mitochondria as mitochondria is the site of respiration and active transport requires energy from respiration.I need three limitations, and ways to overcome them, the one I already have is the the strip size may vary, and you could use a set size cork borer to ensure they're the same size.Could someone help me as to what the other two are?I recently did the osmosis potato experiment, where you cut strips of potato and leave them in different concentrations of sucrose solution overnight.Then you work out the change in mass, and the percentage change in mass.Some strips might have 'skins.' These would act as a barrier to reduce the rate of osmosis. Inconsistent blotting might lead to some strips being left with more excess water than others. potato skin could be left on affecting the results when blotting the chips after osmosis, theres a risk of forcing water out of the cells, affecting the change in mass I forgot the rest lol, need to look over my notes.In order to overcome this you could blot them gently and consistently in circular motions. potato skin could be left on affecting the results when blotting the chips after osmosis, theres a risk of forcing water out of the cells, affecting the change in mass I forgot the rest lol, need to look over my notes.
