Turgid, Flaccid and Plasmolysis are terms used only for PLANT cells.
Instead, for a RBC, terms like haemolysis (bursting or lysis) and crenation (shrinkage) should be used.
State specifically the shape of the RBC as being flattened and bi-concave.
Terms such as Exosmosis and Endosmosis should be used when referring to living cells only. The term Osmosis should be used when referring to experiments with non-living membranes such as visking tubings/dialysis tubings.
When referring to osmosis, use the term water potential, not water concentration as well as water potential gradient, not concentration gradient.
If there is equal water potential in both cell and solution, state that the water potential gradient is zero resulting in no net movement of water molecules, thus no osmosis.
