spore

 [spor]
1. a refractile, oval body formed within bacteria, especially Bacillus and Clostridium, which is regarded as a resting stage during the life history of the cell, and is characterized by its resistance to environmental changes.
2. the reproductive element, produced sexually or asexually, of one of the lower organisms, such as protozoa, fungi, or algae.

spore

(spōr),
1. The asexual or sexual reproductive body of fungi or sporozoan protozoa.
2. A cell of a plant lower in organization than the seed-bearing spermatophytic plants.
3. A resistant form of certain species of bacteria.
4. The highly modified reproductive body of certain protozoa, as in the phyla Microspora and Myxozoa.
[G. sporos, seed]

spore

(spôr)
n.
1. A small, usually single-celled reproductive body that is resistant to adverse environmental conditions and is capable of growing into a new organism, produced especially by certain fungi, algae, protozoans, and nonseedbearing plants such as mosses and ferns.
2. A megaspore or microspore.
3. A dormant nonreproductive body formed by certain bacteria often in response to a lack of nutrients, and characteristically being highly resistant to heat, desiccation, and destruction by chemicals or enzymes.
intr.v. spored, sporing, spores
To produce spores.

spore

1. A dormant or resting stage of certain bacteria and other organisms, capable of surviving for long periods in hostile environments and of reactivating under suitable conditions.
2. A single-celled propagative form of a fungus capable of developing into an adult.

spore

a reproductive body consisting of one or several cells formed by cell division in the parent organism, which, when detached and dispersed, and if conditions are suitable,germinates into a new individual. Spores occur particularly in fungi and bacteria and also in Protozoa. Some have thick, resistant walls which enable them to overcome unfavourable conditions such as drought. Usually they are produced in very large numbers, and occur as a result of either sexual or asexual reproduction.

Spore

A dormant form assumed by some bacteria, such as anthrax, that enable the bacterium to survive high temperatures, dryness, and lack of nourishment for long periods of time. Under proper conditions, the spore may revert to the actively multiplying form of the bacteria.
