Spore

Preventing exposure to areas where the organism lives can reduce risk of blastomycosis, but this may be impractical, especially for dogs who live near these areas. Spores may be more likely to go airborne during dry weather, when the contaminated dust is lighter. It is not easy to predict exactly where the Blastomyces organism may be growing, and is thus difficult to avoid entirely. Avoiding the dense, dark areas where the fungus would thrive is the best prevention which will reduce the dog's risk of…

vascular plant that develop haploid spores in order to reproduce. In a typical fern life cycle, the parent fern will produce haploid spores inside of multicellular structures called sporangia, which are found on the underside of the leaves of a mature fern plant in groups or clusters known as sori (Cordle et. al. 2007). Once the spores are produced they will disperse and will eventually undergo mitosis under favorable conditions in order to produce small gametophytes which will eventually mature…

Press lightly on the cover slip to rupture the spore casings but not the asci. 7. Place the slide on the microscope. 8. Using 10x objective, find an area of hybrid asci. 9. Increase the objective up to 40x. 10. Record the images on the slide. 11. Count at least 50 asci for each cross. 12. Record results. 13. Calculate the percentage of asci that show crossing over. 14. Calculate the recombination frequency. Hypothesis The percent of asci showing crossing over will be 56% before dividing by…

For example, seed-bearing plants have many ways of pollination whereas, spores have a singular dispersal method. The terminal sac that rests upon the end of the filament stalk, the anther, contains the pollen grains. Those pollen grains can be dispersed either by a bump of a insect or even by hitchhiking on a simple breeze. Whereas spore-producing plant have to rely solely on a gust of wind. Angiosperms also possess multiple protective and defensive structures that bryophytes lack. Flower…

in the most severe cases, brain or nerve damage and even death. If it tests positive and have symptoms mentioned in this article, seek medical attention. Why are we seeing more mold symptoms recently? Well, now that more homes are being built to be energy efficient, water-damaged buildings can't "breathe". This creates a perfect, ripe environment for mold spores to thrive. Another cause is from the transition of plaster to drywall. Wet drywall tends to be a very good place for it to…

Crupina vulgaris Crupina vulgaris is a class A federal noxious weed under the asteraceae family and dicot group, and is part of the spermatophyta subdivision that produces seeds (Natural Resources Conservation Service 2016). C. vulgaris is commonly known as Bearded creeper or Common crupina. It is a winter annual weed that can grow 1 m or 1 to four feet tall (Crupina vulgaris 2015) with three sterile and two fertile flowers (Crupina vulgaris (bearded creeper) 2011) pink to purple in color. C.…

Stachybotrys (black mold) is a dark green almost black slimy mold that produces a deadly poison called mycotoxins. It often grows on cellulose based items like straw and paper after coming into contact with water. Stachybotrys enters a person’s system through the spores. Spores are tiny seed like structures which are produced in the mold. Mold spores are invisible to an person’s naked eye. The spores multiply promptly after coming into contact with water. Mycotoxins are present on the surface…
