Question Description


The goal for this project is to design a well thought-out laboratory experiment that you could carry out in a lab or even at home. You will develop the hypothesis, the method (design) for the experiment; a plan on how to collect the data, possible outcomes, and conclusions. In short, you will develop everything that needed for an experiment without actually testing it.

Please take a very close look at the rubric at the end of this document. It will help you to understand how you will be graded and expectations for in this assignment.


  • Use resources such as microbiology text books, encyclopedias, HCC Library databases (e.g. Pro Quest Biology, Pro Quest Nursing), journals, and online medical sites to research these questions. Indicate the source of information either in ACS or MLA format. Do not forget to include in-text citations every time you borrow someone’s idea, even if you paraphrased it. Be sure to include the publication date.
  • Comment on the reliability of the source (why you think this source is reliable … “because it is on the internet” is NOT a good answer) under each reference.
  • All references must be cited, and direct quotes from the references must be indicated as such, using quotation marks. However, in science writing, direct quotes are seldom used. Instead, paraphrase the information in the reference, and supply the citation.
    • In the case of plagiarism, all students involved will receive a “0” on this assignment. Thereafter, plagiarism will be handled according to the College’s Academic Honesty Policy.

ABSTRACT

Multicellular organisms utilize specialized cells to absorb water from the soil. In plant
cells, the network of cells is large and extended. We investigated the ability of different sizes
of potato slices to absorb water. To accomplish this task, we used different slices of varying
sizes in a beaker full of distilled water after determining their respective weights. The samples
demonstrated the process of osmosis albeit at different rates. The difference in mass, recorded
before and after immersion, was calculated in percentage. The results of the experiment
demonstrate that the greater the mass of the potato slice, the higher the percentage gain.
Generally, the results demonstrate that plants are dependent on the process of osmosis to
absorb water molecules.
INTRODUCTION
Plants rely on the process of osmosis to obtain water, which is vital for their growth
and development. Specialized cells that perform this function are found in the roots, leaf cells,
and stem cells of plants. Osmosis refers to the diffusion of water molecules via a
semipermeable membrane. Studies reveal that the diffusion of water occurs through the
membrane from a region of high water concentration to a region with low water
concentration. When water diffuses into the cells of a plant, the cells expand but do not burst
since they are surrounded by a cell wall. As a result, the cells become swollen and hard
(Howlett, 2013). There are numerous factors that can influence the rate of osmosis in cells.
These include the density of the substance, the temperature, the thickness of the cell wall, and
the concentration gradient.
In this experiment, we measured the ability of potato slices to absorb distilled water.
Each slice sample was of different size and the corresponding weights were measured before
and after the experiment. Acknowledging that the greater the mass of the potato, the more
