Therefore to conclude that all cell membranes act in this way would be incorrect.Different plant cell membrane may be adapted to cope better or worse than beetroot cell membranes.

From this experiment the cell membrane from the beetroot would show how much ethanol would affect it's cell membrane and the level of damage at what concentration or ratio with distilled water.

From the results it would give scientist predictions of the effect of ethanol on a persons stomach or digestive lining.

Coleus leaves are ovate in bees wax, digital balance, beaker.

Finally, the blotted TLC plate in the 9: After filtration, we obtained the filtrate in the beaker. This research will give insight in the staining capability of the aqueous and ethanolic extracts from Syzygium cumini, Coleus blumei Benth. The reverse was true for the stems as they were found out to facilitate bacterial growth instead of impeding it.

Learn with extra-efficient algorithm, developed by our team, to save your time.

Introduction Biology Coursework Beetroot Hypothesis: To investigate the effect of different concentrations of ethanol on the permeability of beetroot cell membranes.

Prediction: By exposing a membrane to a solvent, ethanol, it will affect its permeability.

Therefore higher the concentration of the solvent, the more permeable the membrane will be.

The cell transports ions and small molecules across their membranes by the following means: Osmosis: By osmosis the diffusion of water through the plasma membrane is possible.

Since the lipids bilayers are impermeable to essential molecules and also to a few small molecules like oxygen and carbon dioxide, these molecules and ions diffuse freely across the cell membrane. Middle This previous testing provided a basis for a method and suitable equipment that may have been needed for the preliminary and final experiment.
