Answer:

Endosmosis

When a cell is kept in a hypertonic solution, the water starts moving into the cell from a region of higher concerntration to the region of lower concerntration is called endosmosis. As a result the cell swells up.

Activity -

Buy some raisens

Put them into a hypertonic solution (eg. water)

Now wait for some time and observe the raisens.

The raisens starts swelling up.

Observation - Through this activity we observe that after putting raisens in hypotonic solution the raisens swells up. Their is also an increase in thier weight.

Exosmosis

When a cell is kept in a hypotonic solution, the inner content of cell shrinks as the water moves from the region of higher concerntraion to the region of lower concerntration. This is called exosmosis.

Activity -

Buy some raisens

Put them in a hypotonic solution (eg. A sports drink with a lot of salts in it)

Wait for a while and observe that the cell starts shrinking

Observation - Through this actvity we observe that after putting raisens in a hypotonic solution the raisens starts losing water content and gets shrinked.
