Which of the following is a similarity between the processes of diffusion and osmosis?
A
Both require energy input to occur.
B
Both occur only in living organisms.
C
Both involve the movement of water molecules only.
D
Both involve the movement of particles from a region of higher concentration to a region of lower concentration.
Verified step by step guidance1
Begin by understanding the definitions of diffusion and osmosis. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water molecules across a semipermeable membrane from a region of higher water concentration to a region of lower water concentration.
Recognize that both diffusion and osmosis are passive transport processes, meaning they do not require energy input to occur. This is because they rely on the natural kinetic energy of particles and the concentration gradient.
Consider the environments in which diffusion and osmosis occur. Both processes can occur in living organisms as well as in non-living systems, such as in solutions or across synthetic membranes.
Identify the types of molecules involved in each process. Diffusion can involve any type of particle, including gases, solutes, and solvents, whereas osmosis specifically involves the movement of water molecules.
Conclude that the similarity between diffusion and osmosis is that both involve the movement of particles from a region of higher concentration to a region of lower concentration, driven by the concentration gradient.
