What might happen to a freshwater plant that is placed into saltwater?
A
Cells will swell
B
Plasmolysis
C
Cytolysis
D
There will be no change
Explanation: 

Detailed explanation-1: -If you water a plant with salt water, it will wilt, and will eventually die. This is due to the fact that the salt water is a hypertonic solution when compared to the plant cells, and water inside the plant cells will diffuse by osmosis out of the cells in order to reduce the concentration of the salt solution.

Detailed explanation-2: -5. 6. When plant cells are put in really salty water, water diffuses/moves out of the cell and the central vacuole shrinks. When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up.

Detailed explanation-3: -When a plant cell is placed in concentrated salt solution, water concentration inside the cell is greater than that which is outside the cell. Therefore, water moves through the cell membrane into the surrounding medium. Ultimately the protoplasm separate from the cell wall and assumes spherical shape.
