Answer:
The plant cell becomes turgid
Explanation; freshwater contains a low amount of salt concentration .when cells are placed in it,it creates an osmotic difference, as the cytoplasm of the cell would be of higher concentration than the surrounding water .as a result,water moves into the cell by osmosis.
Most Unicellular organisms has organelles such as contractile vacuole to expel excess water out of it's cell.if the animal cell is unable to expel water,it bursts.
In plants cells,the cell swells and the swelling is checked by the inflexible and rigid cell wall.
The cell wall of plants are made of cellulose, lignin and pectin.
The possible combinations are as follows
R r
R RR Rr
r Rr rr
so you would have a ratio of 1RR : 2Rr : 1rr
