Invasion Introduction: In this survey we are planning to understand what factors influence the invasion rate of potato cells. Transmission is a concentration gradient that moves from a high concentration to a low concentration through a partially permeable membrane. I weigh the chips back and forth, and if the weight gets increased, it means that the concentration of potato chips is lower than the liquid it is. So penetration is happening. [IMAGE] Vocabulary (citation from the Internet - confirmation of reference) Penetration - liquid diffuses through a semipermeable membrane or a porous separator.

Permeate permeated through the permeated plant cells after permeation is transferred from cells in water to cells by permeation. Cell membranes of plant cells are selectively permeable. Therefore, when a cell containing a weak solution (a large amount of water) is close to a cell with a strong solution (a small amount of water), water moves from a weak solution to a strong solution as shown in the figure. Conclusion The viscous tube is a selective permeable membrane. This means that it will only allow some particles to pass through it. In this experiment, glucose particles are too big, so only water particles can pass through. The concentration of glucose particles in the viscous tube bag is high and only the water particles can move completely freely so that water particles from the outside of the bag enter it and make the concentration uniform. This is due to popularization. Therefore, as more water particles enter the viscous tube pocket, the liquid level rises in the capillary.

Penetration has the same basic theory as diffusion. The particles move from the area where they are highly concentrated to the area where they are low concentration until the concentrations are the same. Penetration is the movement of water particles that must pass through a semipermeable membrane or a partially permeable membrane (a membrane that allows something to pass through, not something else). An example of this type of membrane is a cell wall like a potato. When two things happen, penetration occurs. In some cases, if the cells do not contain water or water, they are placed in solution. In this case, water enters the cell in a region where the concentration of water is high, and water is flowing out of the solution because it is a region where the concentration of water is low. If there is no water in the cell, the cell is loose. As water passes through the cell membrane, the cells are filled with water and expand. As the cells swell, no more water enters the cells and the infiltration ceases.
