(Be sure to clearly state the principles addressed in your discussion.) 9. Choose THREE of the following four types of cellular transport.
Describe the fluid-mosaic model of a plasma membrane. Include a description of mitosis and cytokinesis, and of the other phases of the cell cycle. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Discuss the role of the membrane in the movement of materials through it by each of the following processes: 6. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions.
