You are viewing two samples of mammalian red blood cells (erythrocytes) under a microscope. One first sample is made up of cells with a typical round shape. Most of the cells in the second sample had burst open. • Describe the properties of the solution that was used to prepare the second sample. Identify one type of solute that can move through simple diffusion and does not affect osmotic pressure or require a membrane protein to cross a plasma membrane.

The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.

Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport (b)Using the same transport types, identify a specific cell that utilizes that type of transit (i.e. one cell for each transport type, or two different cell examples), and detail a substance that is transferred. (c)A typical human lymphocyte has a radius of about 10 μm, while a typical bacterium (e.g., S. pneumoniae) has a radius of about 1 μm. Assuming that both cell types are perfectly spherical, compare and contrastthe transport mechanisms for each of these cells.
