My first SAC is next week and I'd really appreciate if someone could please check if this aim, hypothesis and observations are valid and any possible changes I can make in order to achieve the best I possibly can.
Aim:
What you will be investigating – the aim of the experiment was to investigate Osmosis in a plant cell when placed in solutions with different solute concentrations.
Hypothesis:
The educated guess as to what will happen –
* When the cell is placed in the hypertonic solution, water will move out of the cell by osmosis and the cells will plazmolyse.
* When the cell is placed in the hypotonic solution, water will move into the cell by osmosis and it will become turgid.
* When the cell is placed in the isotonic solution, there is no net movement of water molecules and so the plant cell becomes flaccid.
Observations:
* The plant cell mass decreased when it was placed in the hypertonic solution because water moved from an area of low solute concentration to high solute concentration, out of the cell, causing it to plazmolyse.
* The plant cell placed in the hypotonic solution had an increased mass as water moved in from an area of low solute concentration to high solute concentration, into the cell, causing it to become turgid.
* There was no mass change in the plant cell placed in the isotonic solution because there was no net movement of water, and so the plant cell remained flaccid.
