DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Is the following an example of OSMOSIS or DIFFUSION? The student sitting next to you just came from gym class and forgot to shower and you can tell.
A
Osmosis
B
Diffusion
Explanation: 

Detailed explanation-1: -thus the correct answer is diffusion.

Detailed explanation-2: -To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane. Examples of Diffusion: Examples of diffusion include perfume filling a whole room and the movement of small molecules across a cell membrane.

Detailed explanation-3: -Final Answer: Uptake of water by root hair and swelling of seed when put in soil are examples of osmosis.

Detailed explanation-4: -A tea bag immersed in a cup of hot water will diffuse into the water and change its colour. A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. Sugar gets dissolved evenly and sweetens the water without having to stir it.

Detailed explanation-5: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
