In diffusion, molecules travel from a higher concentration to a lower concentration. When you put a drop of ink in a glass of water, the spreading of the ink in the water is called diffusion. Similarly, if you spray an air freshener in one corner of a room, eventually people on the other side of the room will be able to smell it as well because the scent has diffused.
In osmosis, molecules also travel from higher concentration to a lower concentration. However, osmosis specifically refers to the movement of WATER molecules. Both of these types of transport are examples of passive transport, which requires no energy.
Osmosis is for solids only, while diffusion is for both gases and liquids.

What is the difference between passive transport active transport diffusion and osmosis?
the main difference is that active transport requires ATP (energy), where as osmosis and diffusion do not. However, there are a lot of other differences in what they actually do to the cell.
Which are types of passive transport?
Diffusion - spreading of molecules in solid, liquid and gas Osmosis - diffusion of water; affected by tonicity Facilitated diffusion - transports of substances are facilitated by carrier proteins
Does dissolved minerals enter into the root hair by osmosis not by diffusion?
Dissolved minerals primarily enter root hairs through the process of active transport, where the plant expends energy to move minerals against their concentration gradient. This is a primary mechanism for absorbing essential nutrients such as nitrogen, phosphorus, and potassium. Osmosis and diffusion play a role in water uptake and movement within plant tissues but are not the main routes for mineral absorption.
What are the three things that affect diffusion?
Three main factors that affect diffusion are temperature (higher temperature increases rate of diffusion), concentration gradient (greater difference in concentration leads to faster diffusion), and surface area (larger surface area allows for more diffusion to occur).
What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
How is diffusion and osmosis similar?
Diffusion and osmosis are both passive transport processes that involve the movement of molecules from an area of higher concentration to an area of lower concentration. The main difference is that osmosis specifically refers to the movement of water molecules across a semi-permeable membrane, while diffusion can involve any type of molecule.
How is osmosis the same as diffusion?
Osmosis and diffusion are similar in that they both involve the movement of particles from an area of higher concentration to an area of lower concentration. The main difference is that osmosis specifically refers to the movement of water molecules across a semipermeable membrane.
What is the difference and similarities between osmosis and simple diffusion?
Osmosis 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. Simple diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. The main similarity is that both processes involve the movement of molecules across a membrane, but osmosis specifically refers to the movement of water molecules.
What is diffusion of oxygen all about?
Diffusion is the main method by which molecules move across the cell membrane. during diffusion, molecules move from an area of higher concentration, to an area of lower concentration. What is Osmosis? Osmosis is the transport of water from an area of high concentration, to an area of low concentration water moves inside and inside of the cell membrane by osmosis. osmosis is the diffusion of water!
Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
How are osmosis and diffusion similar and how are they different?
Osmosis is where the water or other particles go from an area of higher concentration to an area of lower concentration. This is often against a pressure gradient. This type of reaction involves a process known as ACTIVE TRANSPORT where ATP (adenotriphosphate) is required (energy required).Diffusion is where the products even themselves out through a given solution. This process is done by passive transport, where NO energy or ATP are required.Osmosis is diffusion through a semi-permeable membrane.
What types of diffusion do not require energy?
Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
What is the difference between passive transport active transport diffusion and osmosis?
the main difference is that active transport requires ATP (energy), where as osmosis and diffusion do not. However, there are a lot of other differences in what they actually do to the cell.
What is the difference between polyethylene and polyester?

Which are types of passive transport?
Diffusion - spreading of molecules in solid, liquid and gas Osmosis - diffusion of water; affected by tonicity Facilitated diffusion - transports of substances are facilitated by carrier proteins
What is the main difference between the two products?
The main difference between the two products is their ingredients.
