- Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport ๏facilitated diffusion ๏endocytosis / exocytosis (a)For each type of transport you choose, describe the transport process. Explain how the organization of cell membrane plays a role the movement of specific molecules across membrane. (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.
