Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When the glycocalyx is unorganized and loosely attached.
A
Slime layer
B
Capsule
C
Goopy membrane
D
Goober layer
Explanation: 

Detailed explanation-1: -If glycocalyx is more easily deformed and loosely attached to cell wall it is called slime layer, a well-organized layer, not easily washed off. The capsule is considered a virulence factor because it enhances the ability of bacteria to cause disease.

Detailed explanation-2: -2. If the glycocalyx appears unorganized and more loosely attached, it is referred to as a slime layer.

Detailed explanation-3: -Glycocalyx (mucilage sheath) is the outermost layer of the bacterial cell envelope which consists of non-cellulosic polysaccharides with or without proteins. It may occur in the form of loose sheath, called slime layer. If it is a thick covering, it is called capsule.

Detailed explanation-4: -Glycocalyx exists in two forms: slime layer or capsule. Slime layer is the extracellular layer that is loosely associated with the bacterial cell wall. It is a less discrete layer that can be easily washed off. Capsule is attached tightly to the cell wall, and it is a thick discrete layer.

Detailed explanation-5: -If the molecules form a highly organized structure that adheres tightly to the cell wall, the glycocalyx is referred to as a capsule. Both the capsule and the slime layer give the bacterial cell the ability to adhere to surfaces.
