Do you think that fungal cells have turgor pressure? Design an experiment to test your hypothesis.
Answer
Turgor pressure refers to the pressure exerted by the cell membrane against the cell wall, Hence turgor pressure is only observed in cells containing both cell walls and cell membranes. Ex- Plant cells. In the case of plants, high turgidity is observed in epidermal cells. in the root tips, in pollen tubes. Turgor pressure in plants is maintained by the process of osmosis through a semipermeable membrane such as a cell wall. In osmosis, the solvent flows from a region of low solute concentration to a region of high solute concentration till the difference in concentration disappear. When plant cells are placed in a hypotonic solution, water moves from outside to inside the cell and the cell swells up. The cell membrane then exerts the turgor pressure on the cell wall to maintain proper rigidity. In the absence of proper turgor pressure, the cells may wilt or become flaccid.
Yes. I believe fungal cells also have turgor pressure. In order to prove this, three types of cells should be taken.
(A) A fungal cell (the experimental sample)
(B) A cell from the tip of the root that is known to have turgor pressure (positive control)
(C) An animal cell, for ex, human skin cell that is known to not contain turgor pressue (negative control)
Now the three cells should be placed in hypotonic solution. Each cell type should be observed before and after placing them in hypotonic solution.
The plant cell will look rigid and turgid without any disruption, the human skin cell should rupture due to the absence of a cell wall and absence of turgor pressure. If the fungal cell wall remains intact and turgid, similar to the plant cell, we may conclude that it possesses turgor pressure.

Think of observation then form a question and hypothesis. Then, design an experiment you could do to test your hypothesis. Make sure the experimental design is detailed and define all of your variables (the dependent variable, the independent variable, the controlled variable, designing the procedure, level of treatment, replication, the control. ) On a separate sheet of paper, think of an observation you have made and then form a question and hypothesis. Then, design an experiment you could do to...
Design an experiment to test the hypothesis that the amygdala plays a role in the processing of emotional memories.
Design an experiment to answer a question you have about human development. Specify the question and the hypothesis and then describe the experiment. How would you prevent your conclusions from being biased and subjective? Design a simple hypothetical experiment to answer a question you have about human development. Specify the question and the hypothesis and then describe the experiment. How would you prevent your conclusions from being biased and subjective?
Design an experiment that would directly test the hypothesis of the following scenario. Identify the control group, independent variable, and dependent variable. Hypothesis: The plant species Acidicus plantus grows best at pH 2-4.
11.Construct a hypothesis as to whether you think the Mitotic Index of animal cells would be different than a plant cell and make a prediction based on your hypothesis
Generate a hypothesis and briefly describe how you would conduct an experiment to address your hypothesis. Provide specific details such as the type of research, population, and key aspects that you would need to collect your data to test your hypothesis
Do you think it is ethical to design your own baby through gene manipulation
4a. You want to test the hypothesis that the microbiome of a milk-fed infant is different from that of a formula-fed infant. Describe how you would test this hypothesis. 4b. Assuming that you do see a difference in your experiment, how would you then test whether these distinct microbiomes have the same health benefit for developing an immune response using germ-free mice?
B. You would like to test the hypothesis that your molecule can signal through bitter taste receptors using a genetic experiment. Because there are so many different bitter taste receptors, it would not be possible to knock all of them out. However, you do have access to the PLCbeta2 knockout mouse. Describe how you can construct a mouse that retains sweet taste but lacks bitter taste reception. If your hypothesis is correct, what results do you expect in the lick...
