Explanation of Solution
Surface area to cell volume (S/V) ratio:
Diameter of the spherical cell = 15 µm
Surface area to cell volume (S/V) ratio is
Diameter of the spherical cell = 2 µm
Surface area to cell volume (S/V) ratio is
Consequences of the differences in surface to volume ratio: The ratio of surface area to cell volume increases as the size of a cell decreases. In comparison to the cells of larger sizes, cells of smaller sizes possess increased surface area relative to the volume of the cell. Several properties of a cell, including its evolution and growth rate are controlled by its S/V ratio. Due to the presence of larger surface area,

- Cell swimming depends on appendages containing microtubules. What is the underlying structure of these appendages, and how do these structures generate the force required to produce swimming?arrow_forwardList and describe the three main types of cytoskeleton. If you wanted to do immunocytochemistry to specifically stain each type of cytoskeleton, what is a protein that could be used for each cytoskeletal type (in other words, what is a unique protein for each cytoskeletal type)? What are three types of actin structures? Describe the involvement of actin structures in cell migration. How is the growth and shrinking of microtubules regulated? Then describe the roles of microtubules in: chromosomal separation during mitosis and the movement of organelles and vesicles within a cell. Describe a possible mechanism on how signaling pathways might impact the cytoskeleton, so that cell migration could be regulated in a localized manner within a multicellular organism. (hint: think about the possible transcriptional regulation of the G-protein regulators) What are 2 main challenges of protein targeting? Then describe one way these challenges are overcome during signal-based targeting and one way…arrow_forwardThe shape of a yeast cell can be approximated by a sphere.(a) Calculate the volume of each cell using the formula for thevolume of a sphere:V = 43 πr 3arrow_forward

What are a least two examples of this concept?arrow_forwardAmong the statements a, b and c, which is/are false? a) Endocytosis is the formation of vacuoles by the plasma membrane for the purpose oftransport inside the cell a small content of extracellular fluid. b) Exocytosis is the formation of vacuoles by the plasma membrane for the purpose oftransport a small amount of intracellular fluid out of the cell. c) Pinocytosis is a form of endocytosis. d) All of these statements are false. e) None of these statements is false.arrow_forward

The length of the longest cell in the image is approximately ______um. a) 2 um b) 20 um c) 200 um d) 2000 umarrow_forwardSuppose you have a cell from a freshwater fish that is isotonic with its surrounding environment, with a K+ concentration inside the cell of 0.05M. You then immerse this cell in saltwater where the K+ concentration is 0.25M. What would you predict will happen to the cell? a)Water will move into the cell, and the cell will swell and burst b)Water will move out of the cell, and the cell will shrink c)Water will move in and out of the cell with no net change in concentration, and the cell will remain the same size d)The cell wall will prevent the cell from changing sizearrow_forwardplease do (ii)arrow_forward
- Why is mechanical method of cell disruption often employed even after disrupting cells with non-mechanical methods? Briefly explain some of the mechanical methods of cell disruption.arrow_forward-Mature parent cell Budding- cell 1 μη Test II. Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forwardDraw to scale the outline of two spherical cells, one a bacterium with a diameter of 1 μm, the other an animal cell with a diameter of 15 μm. Calculate the volume, surface area, and surface-to-volume ratio for each cell. how would the latter ratio change if you included the internal membranes of the cell in the calculation of surface area (assume internal membranes have 15 times the area of the plasma membrane)? (the volume of a sphere is given by 4πr3/3 and its surface by 4πr2, where r is its radius.) discuss the following hypothesis: “internal membranes allowed bigger cells to evolve.”arrow_forward
