Biological term for layers of fossilised bacteria?
Very few ancient stromatolites contain fossilized microbes. While features of some stromatolites are suggestive of biological activity.
What kinds of slime layer are there?
There are two main types of slime layers: capsular slime layers, which are organized, discrete layers that are tightly bound to the cell wall; and slime capsules, which are unorganized, loose matrices that surround the cell. Slime layers serve to protect bacteria from desiccation, phagocytosis, and antibiotics.
How is the cell wall of Gram-negative bacteria structured?
Two thinner layers of peptidoglycan separated by a small gap. This allows the stain to escape being set and thus these bacteria are Gram negative.
Is not true about capsules and slime layers?
Capsules and slime layers are both forms of glycocalyx produced by bacteria, but it is not true that they are always present in all bacterial species. Capsules are typically well-defined and tightly attached to the cell wall, providing protection and aiding in adherence, while slime layers are more loosely associated and can be easily washed away. Additionally, capsules and slime layers do not serve the same functions in all bacteria; their presence and role can vary significantly among different species.
What is the similarity between slime layer and capsule bacteria?
Both slime layer and capsule are outer protective layers found in some bacteria. They help bacteria adhere to surfaces and protect them from desiccation, predation, and the host immune system. The main difference is that capsules are more organized and tightly bound than slime layers.

What is a zythymn?
Zythymns are a group of prehistoric bacteria that lived mostly in intestines, therefore were discovered in fossilised dinosaur poo!
What is any naturally preserved evidence of life?
Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.

cranidos
How old is a horses fossil?
Yes horses can be fossilised. anything can be fossilised as log as it has a skeleton.
What connection can be made between a fossilized organism and the rock its fossilised in?
nothing.
What is the type of coating on a bacteria cell?
In bacteria, the cell wall is composed of peptidoglycan, and is essential to the survival of many bacteria. Bacteria have been classified into Gram-positive and Gram-negative based on the structure of the cell wall. Gram-positive bacteria possess thick cell wall consisting of many layers of peptidoglycan and teichoic acids. Gram-negative bacteria have relatively thin cell wall consisting of few layers of peptidoglycan.
