Compound figures may require a full page. When a plant cell is placed in a solution that is hypertonic relative to the cytoplasm, water moves out of the cell and the cell shrinks. Much of the results are also reported in the legends.
Show your calculations in the space provided and include them in your report.
Discuss the concepts of osmosis, diffusion, semi-permeable membrane, isotonicity, hypertonicity, and hypotonicity in the introduction portion of the lab report. Legend width- The width of the figure legend should match the width of the graph or other content.
However, if you wanted to show us that sex ratio was related to population size, you would use a Figure.
Error bars are therefore plotted for each point and defined in the legend as well. We performed a lab that studied osmosis in potato cells.
In the examples later in this section, note the completeness of the legends. For the materials each group had to have a Petri dish that contained salt in it and then we added the salt in one of the two beakers filled with water and stirred it with a straw.
In this experiment the length of the potato cylinders is affected by osmosis. Most often black and white is preferred. Chemical gardens demonstrate the effect of osmosis in inorganic chemistry. Usually the osmotic gradient is used while comparing solutions that have a semipermeable membrane between them allowing water to diffuse between the two solutions, toward the hypertonic solution the solution with the higher concentration.
Which way did the water move. Mass weigh each to the nearest 0. Top of Page How to number Tables and Figures: In unusual environments, osmosis can be very harmful to organisms.
From this the correlation coefficient R which is 0. In this example notice: Any photograph from another source requires attribution in the legend. Different methods to control osmosis Aim: Never use a title for Figures included in a document; the legend conveys all the necessary information and the title just takes up extra space.
Osmotic pressure As mentioned before, osmosis may be opposed by increasing the pressure in the region of high solute concentration with respect to that in the low solute concentration region. Then Place each piece flat side down in to one of the plates of water.
The potato slice in the distilled water will decrease in mass. Effect of different solutions on blood cells Micrographs of osmotic pressure on red blood cells RBC Plant cell under different environments. I hope you enjoyed this simple experiment.
In the hypertonic solution the carrot floated and stayed at the top and in the hypotonic solution the carrot sunk to the bottom of the beaker. Lab 4: Diffusion and Osmosis Agar + Potato = Learning. Lab Overview •According to your lab manual, there are three parts to this lab. •We are doing two of them –Procedure 1 and Procedure 3.
–Procedure 1 is an investigation of diffusion through a cube of agar. 1 Osmosis and Diffusion Abstract: This lab is composed of instructor demonstrations, as well as student run experiments meant to demonstrate the various principles regarding osmosis and diffusion. Osmosis is a special case of diffusion, in which water diffuses across a selectively permeable membrane.
In this experiment the membrane will be that of the potato cell. For our purposes we will consider the membrane of the potato to be selectively permeable to H 2 O only. Osmosis Lab Report Essay Sample This experiment is being done to find out what happens to a carrot or a potato if you place them in two different solutions.
Osmosis has a lot to do with this experiment and is the movement of water molecules from a higher concentration to a lower concentration.
Background Information: What do you know? 1. Water moves through cell membranes from areas of _____concentration to areas of _____concentration.
2. If a solute such as. Lab 6: Diffusion and Osmosis.
