Answer: False
Explanation: Osmosis is a process that occurs in both plant and animal cells. It is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. This process is essential for maintaining the balance of water and nutrients in cells. While osmosis is often discussed in the context of plant cells due to its role in water uptake and turgor pressure, it is equally important in animal cells for processes such as nutrient absorption and waste removal.
