What is Difference Between Cell Membrane and Cell Wall

Difference Between Cell Membrane and Cell Wall

 

Cell Wall:

 

Location:

 

It is outer most boundary of plant cell. It is absent in animals cell.

 

Thickness:

 

It may be thick as outer wall of trachieds or as parenchyma tissues.

 

Tissues:

 

  1. i) Parenchyma tissues are composed to thin wall and its function is storage.
  2. ii) Cotenchyma tissues are slightly thick and their function is conduction.

iii) Sclerenchyma tissues are thick wall and their function is protection.

 

Composition:

 

Its composition is different in different plants. Majority composed of cellulose (dead cells). In fungi it is composed of chitin.

 

Types of cell wall:

 

  1. i) Primary cell wall is a thin wall which form first whorl.
  2. ii) Secondary cell wall is formed by deposition of many primary cell walls. It is thick.

 

Functions of cell wall:

 

  1. i) It provides protection to the cell.
  2. ii) It gives shape to the cell.

iii) It provides support to the cell.

  1. iv) It provides rigidity to the cell.

 

Nature of cell wall:

 

Cell wall is permeable in nature because it allows all the materials to pass through.

 

 

Cell Membrane:

 

Location:

 

It is outer most in animal’s ceII while in plant cell it is present inside the cell wall.

 

Thickness:

 

It is few micron meter thick.

 

Composition:

 

Basically is composed of lipids and proteins. It consists of two layers if lipids in which protein molecule are completely embedded.

 

Function:

 

  1. i) All the transportation of cell is done by cell membrane.
  2. ii) It provides the shape to the animal cell.

iii) It provides support to animal cell.

 

Note: From each of the headlines we draw arrows with subheadings, and then – arrows with theses. For example, we write the title “Display Advertising”. Next, we paint existing types of advertising: television, radio advertising, outdoor, internal, Internet advertising. And already for each type of advertising individually we will write a number of theses that we want to remember. What is the advantage of such a scheme in front of usual abstracts? First, we see all the links on one sheet. Losing one of the six headlines on the sheet is much more complicated than several lines in a whole notebook of unstructured text. Secondly, we clearly see which thesis relates to what, and therefore do not confuse the properties or features of any concept. Finally, the main thing is that we start to remember the information with levels, that is, first we will remember the headings to which the subject is divided, then the subheadings. That is, we start with the structure, and only then go to the details. Very often students learn unnecessary private information, while ignoring entire sections, simply because they do not understand the scope of concepts.
