If you turned a frog egg upside down, you would expect it to reorient relative to gravity because the dense yolk granules concentrated in the vegetal hemisphere of the egg respond to gravity.
The frog egg is very large as compared to the normal egg cell. It is unevenly distributed with a top dark colored pole called animal pole and a light yolky pole called a vegetal pole.
The vegetal pole is concentrated with the yolk that is present for providing the nourishment to the growing embryo. The animal pole is the one from where the sperm enters and the development of embryo take place.
As the vegetal pole is denser as compared to animal pole so it will respond to the gravity and reorient along the direction of gravity.

Well I'm not exactly certain where the teacher is going with this, but an often used example is red blood cells (RBCs) aka: erythrocytes.
RBCs are suspended in blood plasma as they flood through vessels around and around the body, so the osmolarity (amount of small particles that affect osmosis) must remain relatively constant. This is termed "isotonic", meaning the same amount of osmosis-influencing particles that are there inside the RBCs' cytosol, within their plasma membranes.
If the plasma osmolarity get too high, called hypertonic (as with extra salt particles) then water inside the RBCs will have an osmotic force driving it out of the cells' membranes, to flow where there are more salt particles. This will lead to cell shrinkage (called "crenation").
Counter to that, if the plasma osmolarity gets too low, as due to low plasma salt with excessive water intake (for example from the condition "water intoxication"), then the plasma will be hypotonic with respect to the intracellular cytosol concentration. This can result in water rushing into the RBCs' membranes via osmosis, causing the cells to swell from discs into spheres (balls), or even rupture and burst (a phenomenon called "hemolysis").
HOPE THOSE EXAMPLES HELP!!
