How does culture age affect the results of a sproe stain?
Spores are formed when cells are under unfavourable conditions, as for the bacteria they are means of survival. So the older the culture the higher the cell number in that culture, which means less nutrients for the cells. Under this conditions cells will start spore production. Depending on the "age" of the culture you can get a mixture of vegetative cells with spores inside and spores that are already released or mostly spores with rare vegetative cells, which means the cells are dead.
What are vegatative cells?
any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes; "somatic cells are produced from preexisting cells";
Of what use is the endospore stain?
The use of endospore stain is to see specialized cell structures. It can tell if some bacterium cells contain higher resistant spores within vegetative cells.
What kind of cells does mitosis grow and repair?
Vegetative Cells...
What are reproductive cells formed on mushroom gills called?
Spores.
Where are spores?
Spores are produced by fungi, bacteria, and green plants. Spores in mushrooms are produced on special cells called basidia.
The function of bacterial endospores is?
i dont know bacterial spores are the highly resistant spores.Infact the spores indicate the resting phase of some types of bacteria,which help to tide over the unfavorable conditions.These spores can also be called as endospores.These endospores contain calcium and dipicolenic acid and hence they are very much resistant.They are resistant to temperature,UV light,disinfectants etc. and thus they protect the bacterium.In the favorable conditions these develop into a new bacterium. some of the organisms that form endospores are Bacillus,Clostridium,Sporosarcina etc
Where spores produced?
Spores are produced by fungi, bacteria, and green plants. Spores in mushrooms are produced on special cells called basidia.
What plant stage produces spores?
Plants produce spores during the gametophyte, or haploid, stages. Spores are the sex cells for the plant. The spores will then germinate and produce new plants.
What do the spores do after they burst from red blood cells?
Infect other blood cells
Why are spores more difficult to stain than vegetative cells?
Spores are very hard and dense, dye is not readily absorbed into the endospore. However, one method of staining is the Schaeffer and Fulton method. The stain is malachite green and the proper method entails preparing a heat fixed smear which is covered by a piece of blotting paper, and flooded with the dye. Wait 15 mins then remove blotting paper and wash. Counterstain with 0.5% Safrinin. Spores appear green.
What are the Difference between vegetative and reproductive parts of flower?
vegetative parts of a flower- i don't know reproductive parts of flower- stamen and pistil... can any one pl tell me what r vegetative parts of flower....
