Are only some bacteria that form spores harmful?
no bactreria form spores only plants do especiall ferns
What is the explanation for the main function of spores?
The main function of spores is to facilitate dispersal and reproduction in organisms such as fungi, plants, and some protists. Spores are structures that are able to survive harsh conditions and travel through air, water, or other means to reach new environments. Once in a suitable environment, spores can germinate and give rise to new individuals.
How bacteria can survive harsh conditions?
With the help of endospores, or thick-walled structures that help the bacteria survive harsh conditions.
Do bacteria reproduce through spores?
Endosposres are intracellular resting cells. With a few exceptions endospore formation is restricted to some large gram positive bacilli. Among cocci and spirila endospores are formed only in few species e.g. Sarcina lutea, S. ureae, Dusulfovibrio desulfuricans. Gramd negative do not form spores or endospores.
What is the function of the spores?
Spores are like the seeds in flowering trees and conifers except they are smaller and many thousand can be released in one spore sac. The spores enable a plant to grow again but only ferns, mosses and liverworts have spores.
What special defenses do spores and capsules have?
Bacteria can form capsules and spores. A capsule is a protective layer around some bacteria. They can be virulent as they can resist the body's defence mechanism. Bacteria can change into bacterial spores when the environmental conditions are unfavourable. In this condition bacteria are inactive. When the environmental conditions become more suitable the bacteria can become active and cause disease. Bacterial spores are extremely resistant and can survive most forms of disinfection and inadequate sterilisation

At what stage in the microbial growth curve spores develop?
Spores form during the Stationary Phase of the Bacterial Growth Curve. During the lag phase or the log phase, things are good for the bacteria, so they arent thinking about what it is like to live without all the resources that they need, so they dont start forming the spores yet. Once the bacteria reach the death phase they are not able to form spores anymore, let alone stay alive. So the only phase that the spore forming bacteria make there spores is during the stationary phase.

What is the significance of the organication?
Endospre foming orgaism are of particular interest in the medical field because it is going to inflience the treatment of bacterial infection if the infecting pathogen is able to form spores. As you might already know, spores are formed inside the bacterial cell and are ejected into the external environment. The spores are quite tough and are able to grow into complete bacteria under the right physical conditions. Hence, killing the pathogen does not ensure the death of the spores as well. The spores can turn into bacteria later. Hence, for spore forming bacteria, the medical procedure has to be designed to get rid of the bacteria as well as the spores.
Is it true that microbes are considered dead if they are not moitle and stop metabolizing?
Not necessarily. They can be dormant, as is the case with bacteria that form spores.

Is a spore a part of a flower?
There are many organisms that form spores including bacteria, algae, fungi (mushrooms) and some protozoans. Ferns also form spores. Pollen from flowers is considered to be male spores, and may be transmitted by insect contact (bees), or through the wind. Flowers also have ovules, or female spores.
Why do bacteria that form spores present a greater health risk than those that don't form spores?
Spore forming bacteria are resistant to heat, cold etc. They r not killed when subjected to high temp. So when they get suitable conditns they start growing nd effect the host or the place where they r present...
What shape are gram negative bacteria?
Gram negative bacteria is shaped like rods and stained a reddish pink color due to the gram staining process. Gram negative bacteria do not form spores.
