Bacteria only found in dry areas as cysts?

In summary, the smallest organisms such as bacteria, protozoa, and unicellular algae are usually found in water or a saturated atmosphere. However, when they are found in dry situations, they are in the form of cysts or spores. This is because living bacteria cannot survive in a dry environment.

Hi!
I'm doing a worksheet on Body Size, Heat Loss and SA/Vol Ratio.
The question I'm confused by is:

"The smallest organisms such as bacteria, protozoa and unicellular algae live in water or a saturated atmosphere. They are only found in dry situations as cysts or spores. Why?"

The wording is kind of confusing, but basically WHEN they're found in dry situations, why is it as cysts or spores? It should probably be somehow linkable to the topic.

Thanks! Any help would be appreciated http://biology-forums.com/Smileys/default/smiley-normal.png
(Not sure if this is where this is meant to go, sorry)

What would happen to a living bacteria put in the dry environment?
 

What are bacteria only found in dry areas as cysts?

Bacteria only found in dry areas as cysts are a type of bacteria that have adapted to survive in dry and harsh environments by forming a protective spore-like structure called a cyst.

How do bacteria form cysts in dry areas?

In order to survive in dry areas, bacteria will form cysts by developing a thick and protective outer layer around themselves. This allows them to withstand extreme temperatures, lack of nutrients, and other environmental stresses.

What is the purpose of bacteria forming cysts in dry areas?

The purpose of bacteria forming cysts in dry areas is to ensure their survival in harsh conditions. The cysts protect the bacteria from drying out, extreme temperatures, and other environmental stresses that would normally kill them.

How long can bacteria survive in cyst form in dry areas?

The length of time bacteria can survive in cyst form in dry areas depends on the specific type of bacteria and the conditions of the environment. Some bacteria can remain in cyst form for years, while others may only survive for a few months.

How do bacteria return to their active form from cysts in dry areas?

When conditions become favorable for growth, bacteria will return to their active form from cysts in dry areas. This process is known as germination, where the protective outer layer of the cyst breaks down and the bacteria can resume their normal metabolic activities.
