Endospores and exospores are two types of spores produced by an organism. The main difference between endospores and exospores is that endospores are produced in the cell wall of the parent cell and released into the environment by tearing the cells, while exospores are produced by cell division and by the barrier is separated from the parent cell.
Endospores are mainly produced by bacteria and can resist extreme environmental conditions. In contrast, fungi and algae produce spores during asexual reproduction. Both endospores and exospores can be considered germ cells because they grow to produce new organisms.
What is Spores?
Spores are solitary and reproductive structures and are highly resistant to harsh environmental conditions (such as pH, high temperature, salt concentration, etc.). These reproductive structures exist in variables, size, shape, and number. The phenomenon of sporulation of plant cells is called sporulation or sporulation.
Depending on the situation, these spores are usually divided into two different types:
Endospore and Exospore
Endospores and exospores are two types of spores or reproductive structures produced as a stationary system. Endospores are the most common type of spores and are mainly produced by bacteria.
External spores are produced in eukaryotic cells of fungi, algae, and cyanobacteria. Internal spores are formed inside the parent cell, while external spores are formed at the end of the parent cell and released as buds.
Difference between Endospore and Exospore in Tabular Form
|Endospores are formed within the vegetative cell or inside the cell.||Exospore cells are formed either one of the ends of vegetative cells in other words, on the surface of cells.|
|They are formed inside the parent vegetative cell.||Exospore is formed outside the vegetative cells with the help of budding at one end of the cell.|
|They are highly durable dehydrated cells and can survive in the extreme heat conditions, freezing and toxic chemicals, radiation and also in freezing.||They do not contain dipicolinic acid.|
|Endospores are also called “ resting cells”||Highly resistible of desiccation and heat.|
What is Endospore?
In this article, let’s explore more details about the difference between Endospore and Exospore.
Subcontractors are resistant structures produced by bacteria that can survive in adverse environmental conditions. Endospores contain DNA and small cytoplasm and are covered by a protective shell. When environmental conditions become favorable, endospores sprout new organisms. Therefore, internal spores are considered a type of germ cell.
Bacterium, Bacillus, Clostridium, and Bacillus produce internal spores. These spores can withstand extreme conditions such as dehydration, high and low temperatures, chemicals and ultraviolet radiation.
The inner cell wall is made of dipicolinic acid, which is heat resistant inside the endospores. Treatment of humid heat for 15 minutes at 121 ° C may destroy bacterial spores.
What are exospores?
Exospores are another resistant bacterium produced by fungi and algae and are mainly used to reproduce under adverse conditions. By dividing cells, external cells develop from the ends of the parent cell. Exospore separation occurs by forming a barrier between mother cells and daughter cells. Exospores sprout. Under favorable conditions, buds are released from the parent cells for germination. Conidia are a type of fungal bacteria that are produced in the form of exospores.
Algae are produced by the exospores of Chamaesiphon and Stickhosiphon. It produces bacteria such as actinomyces, streptomyces, actinomyces, and exposure. It also produces blue bacteria such as Chamaesiphon exospores.
Similarities between endospores and exospores
- Endospores and exospores are two types of spores produced by fungi, algae, and bacteria.
- The process of producing bacteria is called sporulation.
- Usually, internal and external spores are produced under adverse environmental conditions.
- Both internal and external spores can be considered germ cells.
- Both internal and external spores are unicellular.
- Both internal and external spores are highly resistant structures.
- Both internal and external spores can remain non-nutritive because their metabolic rate is very low.
Endospores and exospores are two types of spores produced as stationary units. Spores are mainly produced by bacteria. Capsules are produced by fungi, algae, blue bacteria, and bacteria. Internal spores are produced inside the parent cell. However, external spores are produced at the end of the parent cell and released as buds. This is the difference between endospores and exospores.
