Chapter 5 micro notes - Entire outline for lesson 5 - TCCD
Both vegetative cells and endospores have close similarities but quite different. Endospores are released in the environment by rupturing or tearing of the cell. In contrast, the formation of a septum results in the separation of exospore from its mother cell. Endospores are resistant units produced by bacteria to overcome adverse environmental conditions whereas fungi and bacteria produce exospore during asexual reproduction. Endospores are a bacteria’s defence mechanism, a tough nut to crack and an increasing problem in hospitals. Is there a way that we can effectively reduce their presence in the environment and gain the upper hand in our fight against infection?
Highly durable, non-growing, cell-like structure produced by certain, mostly Gram- positive Endospores ______. a. are reproductive structures of some bacteria b. occur in some archaea c. can cause shock, fever, and inflammation d. are dormant, The endospores are dormant forms that are structurally and biochemically different from the corresponding growing or vegetative cells. These bacterial Gram-positive endospore-forming rods are rod-shaped bacteria that form endospores.

A bacterium, in itself, is already smaller than a eukaryotic cell. Therefore, considering the small size of endospore, a small volume of it can already contain a large quantity of it. Endospores are hard to eradicate. Endospores are formed, as the name suggests, inside the bacterial cell.

A bacterium, in itself, is already smaller than a eukaryotic cell. Therefore, considering the small size of endospore, a small volume of it can already contain a large quantity of it. Endospores are hard to eradicate. Endospores are formed, as the name suggests, inside the bacterial cell. Endospores are highly resistant and can be formed by members of the phylum Firmicutes .

In endospore formation, the bacterium divides within its cell wall. One side then engulfs the other. An endospore is a dormant, tough, non-reproductive structure produced by a small number of bacteria from the Firmicute family. The primary function of most endospores is to ensure the survival of a Endospores are a subclass of spores that are very resistant to harsh conditions. They can survive high heat (>100 °C), drying, radiation, and many damaging chemicals. Endospores can germinate many years after formation, even millions of years later.
