5 Questions
What is osmosis?
Osmosis is the net diffusion of water across a membrane, or the passage of water from an area of high concentration to an area of low concentration through a partially permeable membrane.
What is osmotic pressure?
Osmotic pressure is the pressure that must be applied to a solution to prevent net flow of water in response to an osmotic gradient. The greater the osmolarity, the greater the osmotic pressure.
What is osmolarity?
Osmolarity is the total concentration of a solution, which determines the water concentration in the solution. Higher osmolarity results in lower water concentration.
What is tonicity?
Tonicity is a term used frequently in a medical context and refers to the effect of a solution on cell volume. It is often misunderstood as it is defined in at least three different ways.
What are aquaporins?
Aquaporins are a group of membrane proteins that form channels through which water can diffuse across the plasma membrane.
Test your knowledge of osmosis, osmolarity, and tonicity with this quiz. Explore the concept of water diffusion across membranes and the role of aquaporins. Perfect for students and anyone interested in understanding the fundamentals of cellular biology and its relevance to cancer.
