Question
Chapter 47.2, Problem 1CS
Summary Introduction
To determine: The context in which the fusion of intracellular vesicles with the plasma membrane of the cell occurs.
Introduction: The fusion of intracellular vesicles is an important process for the various types of transport processes of the cell. The signaling and transportation of various molecules are based on the fusion between vesicles and cell membrane.

Let's wrap up this brilliant learning experience with another exciting activity. As you have gone through the lesson, most cells exist in an aqueous environment. Their cell membranes selectively obtain certain materials from this liquid environment for them to remain alive and prevent some harmful materials from entering. Also, their cell membranes expel out harmful substances, like the waste products of cellular activities, and prevent essential substances from leaving. But what do you think would happen to a cell if its cell membrane lost its selectivity? Make an illustration (with a title) that shows your response to this question.arrow_forward

The cellular membrane is critical to the maintenance of homeostasis in living organisms. The cell membrane separates the cell from the external environment and plays a critical role in regulating movement of material in and out of the cell. Additionally, eukaryotic cells are made complex by the presence of internal membranes that form organelles, so the cells may become specialized. These organelle membranes create compartments within the cell that can do specific functions. For this exercise, you will work in groups of four to progress through the activities. At the end of each activity, one group (chosen at random) will share how they responded and open the floor for further discussion.
