Final answer:
Bacterial and plant cells resist effects of hypotonic solutions due to their rigid cell wall, which prevents them from bursting by osmotic pressure and helps maintain structure and turgor pressure.
Step-by-step explanation:
The presence of a cell wall enables bacterial and plant cells to resist the effects of hypotonic solutions. In such solutions, water tends to enter the cells due to osmosis. The cell wall provides structural support and rigidity, allowing the cell to withstand the osmotic pressure without bursting. Various living things, including bacteria and plants, rely on their cell walls for osmoregulation. The cell wall in bacteria is often made of peptidoglycan, and many bacteria have an additional protective capsule. In plants, the cell wall is made of cellulose, which not only provides protection but also maintains the cell's shape, helps prevent dehydration, and produces turgor pressure when water enters, supporting the structure of nonwoody plants.
