Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The diffusion of water across a selectively permeable membrane is called
A
active transport
B
facilitated diffusion
C
osmosis
D
phagocytosis
Explanation: 

Detailed explanation-1: -Osmosis is a simple diffusion process. The process of spontaneous net flow of solvent molecules from a selectively permeable membrane into a region of high solute concentration is referred to as osmosis.

Detailed explanation-2: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Detailed explanation-3: -Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
