Answer:
C) Stay the same
Explanation:
Bacteria have rigid cell walls around their cell membrane. When placed in a hypotonic solution, water enters into the bacterial cell by the process of endosmosis. However, the rigid cell wall resists the increase in the volume of the cytoplasm.
The entry of water into the bacterial cell results in the build-up of turgor pressure inside the cell. Build up enough pressure inside the cell prevents the entry of water into the cell. So, when placed in a hypotonic solution, bacterial cells stay the same due to the presence of rigid cell walls.
