Final answer:
The transport of materials through an epithelial cell is known as transcellular transport, which involves substances passing through the cell itself and may include processes like endocytosis and exocytosis.
Step-by-step explanation:
The transport of materials through an epithelial cell is called B. transcellular transport. This process involves substances passing through the cell's cytoplasm and across cell membranes, a journey that could involve vesicle transport like endocytosis and exocytosis. Let's briefly explore the main types of cellular transport:
Options such as paracellular transport involve substances moving between epithelial cells, while exocytosis is the process of vesicles fusing with the plasma membrane to release contents outside the cell, a type of bulk transport. The question concerns materials moving through the cell, not between or out of them, so transcellular transport is the correct answer.
