All of us inhale a few dozen spores every day and are no worse for wear.
Ultrafiltration membranes remove more than 99 percent of bacteria, molds, and spores from drinking water, and can be used at home.
As a result of the small size of the spores, anthrax is virtually impossible to see, smell, or taste.
The principle involved is that the first boiling destroys the growing cells, but not all spores.
In the latter species there are only two spores in an ascus.
Then came the experimental evidence of Davaine and Koch, who demonstrated the development of bacteria from spores.
Some send off spores with a sharp puff, as if shot from a little gun.
It includes all the fungi that have the spores enveloped in delicate sacs called asci.
They're his spores, or eggs, or seeds—call 'em what you want.
The fruit-cases of certain Cryptogams containing sporangia or spores.
A small, usually single-celled asexual or sexual reproductive body that is highly resistant to desiccation and heat and is capable of growing into a new organism, produced especially by certain bacteria, fungi, algae, and nonflowering plants.
A dormant, nonreproductive body formed by certain bacteria in response to adverse environmental conditions.
A reproductive cell or group of cells, produced by some plants, that is capable of developing into an adult plant without combining with another reproductive cell. Plants also produce sperm cells. The spores of nonflowering plants are analogous to the seeds of flowering plants. (See asexual reproduction; compare sexual reproduction.) Fungi and algae typically reproduce by means of spores that are carried by the wind or some other agency to a new location for growth.
