Cell Biology Protective Layer for Bacteria
Not what you're looking for?
I am wishing for information on the cell wall. I have read much information from books and/or websites that has provided a plethora of information. Thus, I was wishing for a breakdown from an individual as I thought that it would provide a better understanding than a textbook definition. I understand that it considered protection for the cell, assists with the determinign and/or keeping the shape of the cell, assists in excessive water expansion within the cell, utilized as a protective layer for bacteria. It is composed of primarily are cellulose, hemicellulose and pectin.(from what I gather) That is about where I am at this point. But I have found that there is a primary and secondary cell wall - each has their own function - so I am somewhat confused and looking for guidance.

Hi, welcome to Brainmass!
Yes, you are right. The cell wall can consist of a primary cell wall and a secondary cell wall, although NOT all cells have a secondary wall. Only those cells with relatively thick walls have them. Let us discuss each component in detail:
The Primary Cell Wall - is made up of cellulose, which is a form of complex carbohydrate. In many cells, no further layers are produced (meaning, no secondary cell wall). The primary wall becomes rigid as ...
