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.

Exercise 6 & 7:
Acid-fast stain: what component/structure in the cell wall is stained?; be able to identify the stain technique
and structure stained by sight (micrograph), give example genera (Nocardia and Mycobacterium), disease-
causing species, and diseases
Endospore stain: what component/structure in the cell wall is stained?; be able to identify the stain technique
and structure stained by sight (micrograph), know what endospores are and example genera w/ endospores
(Bacillus and Clostridium);
Capsule stain: be able to identify the stain technique and structure stained by sight (micrograph), and know
how stain is performed (negative stain, why brief heat-fixation and followed by a positive stain)
Flagella stain: be able to identify the stain technique and structure stained by sight (micrograph), identify the
purpose of the stain, differentiate flagellar arrangement: peritrichous, monotrichous, lophotrichous,
amphitrichous, etc)

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
