What are the three types of solutions in biology?
There are three different types of solutions:
- Isotonic Solution.
- Hypertonic Solution.
- Hypotonic Solution.
What solution causes cells to swell?
hypotonic solution
A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.
What happens to a cell in an isotonic solution?
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.
What solution does not change the shape of a cell?

What are isotonic & hypertonic solutions?
Isotonic solutions are most commonly used for regular maintenance of clean, healthy sinuses – a soothing wash to remove excess mucus, dust, and allergens – and for helping address such things as post-nasal drip. A hypertonic solution contains a higher concentration of salt than your body’s fluids.
What are the different types of solutions?
13.1: Types of Solutions – Some Terminology
| Solution | Solute | Examples |
|---|---|---|
| gas | gas | air, natural gas |
| liquid | gas | seltzer water (CO2 gas in water) |
| liquid | liquid | alcoholic beverage (ethanol in water), gasoline |
| liquid | solid | tea, salt water |
Which solution causes osmosis?
hypertonic solutions
In contrast to hypotonic solutions, the high osmolarity and sodium concentration of hypertonic solutions, such as 7.5% saline, causes a free water shift (i.e., osmosis) from the intracellular space to the extracellular space, expanding the extracellular fluid volume by 3 to 5 times the volume administered.
What is isotonic solution?
Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.
What is an isotonic solution in biology?
Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks. From: An Introduction to Biological Membranes (Second Edition), 2016.
What solution maintains cell turgidity?
Complete answer: Osmotic pressure (OP) is responsible for maintaining the turgidity of the guard cells.
What is meant by hypertonic vs isotonic vs hypotonic?
Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.
What is meant by isotonic solution?
Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.
What are the 2 types of solution?
The solutions are of two forms, depending on whether the solvent is water or not.
- Aqueous solution – When a solute is dissolved in water the solution is called an aqueous solution.
- Non-aqueous solution – When a solute is dissolved in a solvent other than water, it is called a non-aqueous solution.

What is a one stop shop in business?
Key Takeaways. A one-stop shop is a business or office that offers multiple services or products to customers. The business strategy behind the one-stop shop is to provide convenience and efficiency to clients, gaining loyalty as well as revenue.
What is a’one-stop shop’?
What is a ‘One-Stop Shop’. A one-stop shop is a company that offers a multitude of products or services to its customers. One-stop shop can refer to a specific location, meaning that all the business a client has can be carried out at that location. For example, a bank may be able to offer you not only personal banking services and loans,…
How has the One-Stop Shop concept evolved?
Eventually, the concept of the one-stop shop expanded over time to include business services. The nuance also shifted from a wide product offering to capture more of the customer’s grocery purchase to one of offering all the complementary products and services to a client in a particular area.
Is there a one-stop shop for home ownership?
The report also calls for a regional housing agency to serve as a one-stop shop for home ownership. The lovely island bakery is a one-stop shop for organic bread as well as a whole host of island produce. We are a one-stop shop for all your marketing needs.
