Most of the water in the beaker travels up through the xylem, and most evaporates through the stomata, into the air.
Our group measured the amount of water in the beaker before and after. When we initially poured the water into the beaker, there was 100mL. The control showed that there was a loss due to evaporation, about 4.5mL, of unaccounted water, and we lost about 9.5mL of water. So, then 5 mL of water must have gone into the celery.
The water traveled through tough tube-like things called xylem, and then some of the water stayed in the stomata, an eye like thing with guard cells that force it open or closed, and most of the water evaporated through the stomata, which are on the underside of leaves. For celerity that had no leaves, the
Investigating the Water Potential of Celery Cells Aim = == I will be investigating the water potential of celery and to find out which solution will be isotonic with the celery cells, in other words equilibrium between the two no water will leave the cell, or enter. I will do this by following this method. Method 1.

Conclusion: Finally, water molecules are moved from high concentration to low concentration Based on the data collected and the results of the experiment, the hypothesis was correct.
If a plant cell is places in a hypotonic solution the cell has a lower water concentration to that of the solution. Water will move into the cell by osmosis from a high water concentration outside the cell to a lower water concentration inside the cell through a selectively permeable membrane. The cell becomes turbid
At point A the graph shows that no change in mass, of the potato, would have have occurred had we used a 0.2 (m) sucrose solution. This suggests that the concentration of water inside the potato would have been equal to the solution outside the potato. At point B (plain water), there is no indication that the cell is increasing in mass. This is because the cell is fully turgid and no more water can enter.

Diffusion and osmosis are necessary for the efficient transport of substances in and out of living cells. Diffusion is the most common and effective transportation process between cells and their surroundings, the movement of a substance along a concentration gradient from high to low, allowing essential nutrients and compounds to be transported without expending energy. Osmosis is a special kind of diffusion, specific to water. In order to observe diffusion and osmosis in real and artificial cells, a series of experiments was put together to observe how the surface area to volume ratio effects the rates of diffusion by using agar in different shapes with different ratios, next the rate of diffusion due to tonicity was observed using different solutions with different tonicities. And lastly live plant cells were submerged in different solutions with varying water potentials to observe how was potential effects the rate of osmosis and diffusion. It was concluded that the larger surface area to volume ratio, the faster rate of diffusion, the hypertonic solutions caused water to leave a cell and the hypotonic solutions allowed water to enter a cell, and that water potential will move from high to low in an attempt to maintain equilibrium.
I feel that our results do not match our hypothesis. We found that the average density of water is 1.03(g/mL) and the average density of the unknown is 0.79(g/mL). That is a 0.24(g/mL) difference. The large difference could’ve been caused by air bubbles in the pipets, or not enough trials. (pg. 15 Table 3) The calculated percent error for the density of water is 3.26% and the density of the unknown is 3.67%, so we still have some area to improve our
Osmosis – Can be said as a movement of water from higher to lower semi permeable membrane, such as a cell wall when it’s smaller the molecules continue to diffuse until the area which the molecules are found reaches a state of equilibrium, such as the investigation of the effect of sucrose solution on mass of potatoes. If the water concentration going inside the tissue of plant cell is higher than the water concentration in the solution, then the cell we lose water through osmosis. This will cause it to shrink and make the plant cell to be in a state of plasmolysis. Also as the potatoes was in distil water solution it could make the cell to swell up as Water moves into the cell vacuole and pushes against the cell wall eventually the cell contains as much water as it can hold the strong cell wall stops the cell busting and when this happen it is said to be turgid. This explains the definition of osmosis, osmosis is a particular type of diffusion involving water molecules, it occurs when two solutions are separated by semi permeable
Osmosis is the passage of water molecules from a weaker solution to a stronger solution through a partially permeable membrane. A partially permeable membrane only allows small molecules to pass through, so the larger molecules remain in the solution they originated in. Solute molecule [IMAGE] [IMAGE] Water molecule [IMAGE] The water molecules move into the more concentrated solution. When water enters a plant cell it swells up. The water pushes against the cell wall and the cell eventually contains all that it can hold.
In cooler regions of the steam becomes water again and arrives in the form of rain or
