In plants, water enters the root cells by osmosis, and moves into tubes called xylem vessels to be transported to the leaves. Water molecules inside the xylem cells are strongly attracted to each other because of hydrogen bonding (this is called cohesion).
Q. In which kind of solution is the concentration?
The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.

Q. How do I make water more concentrated?
You can make chemical solutions by dissolving a solid into water or other suitable solvent. If the solution is too weak you can evaporate some of the solvent to make the solution more concentrated. A simple distillation lets you collect and measure the amount of water removed so you can calculate the new concentration.
Q. Is the concentration of water molecules higher in a hypotonic solution or inside the cell?
The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
Q. What is the role of osmosis in plants?
Osmosis is responsible for the ability of plant roots to draw water from the soil. Plants concentrate solutes in their root cells by active transport, and water enters the roots by osmosis. Osmosis is also responsible for controlling the movement of guard cells.
Q. Is smoke filling up a room an example of diffusion or not?
Answer Expert Verified Yes this is diffusion because diffusion is the movement of particles from high concentration to low concentration, so when smoke go up in one corner then the smoke goes all over the room which is diffusion.
