Why are gram positive bacteria more heat resistant than gram negative bacteria?

Gram positive bacteria contain more peptidoglycan than gram negative bacteria which is the substance responsible for the increased strength of gram positive bacterias cell walls therefore making them more resistant to heat. Gram negative do contain peptidoglycan but much, much less

And because of this extra layer it has the ability to produce endotoxins which is a part of the Lipid A in the (LPS) layer. So unlike gram positive which produces exotoxins, gram negative bacteria can produce Exotoxins and endotoxins.

The Bacteria Sarcina lutea is Gram Positive Because If You Perform the Gram Test It Will Turn The Violet Color Which indicates It's Positiveness. What Makes It Positive Is the Peptidoglycan Located Within The The Bacterium
Is gram positive bigger than gram negative?
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.

Does Tetracycline kill gram positive or gram negative bacteria?
Tetracycline kills both gram positive and gram negative bacteria. The mode of action to which Tetracycline works to kill bacteria is that it inhibits protein synthesis which works against both gram positive and gram negative bacteria.

Why gram positive bacteria typically more resistant that gram negative bacteria to antibiotics that disrupt plasma membranes such as polymyxin B?
Polymixin antibiotics interact with the lipopolysaccharide molecule of Gram negative bacteria. This component forms the outer leaflet of the outer membrane. Gram-positive bacteria do not have an outer membrane or lipopolysaccharide and thus polymixin antibiotics are unable to bind to the cell.
What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.

gram +
Are archaebacteria gram positive or gram negative?
A guess ;positive or negative bacteria spider(insect).
Which Gran Positive or negative which is more serious?
Gram positive bacteria responds to the Gram stain; gram negative bacteria does not. The two bacteria do not respond to the same antibiotics. Right now the most dangerous bacteria is a gram negative bacteria. That could change.
