Micheli, working with fungi in 1718, reported his observations on the germination of mold spores on cut surfaces of melons and quinces. (nzdl.org)
Fungi were placed in the Vegetable Kingdom because of certain similarities to plants such as their lack of mobility, absorptive nutrition, and reproduction by spores. (istudy.pk)
Examples of traditional taxonomic features include the presence or absence of septa in hyphae, fine details of the type, formation and release mechanisms of spores , or aspects of the biology and ecology of fungi. (istudy.pk)
They are the means of asexual reproduction in some of the algae, fungi, and protozoans. (vedantu.com)
Zoospore is a type of asexual spore found in algae and fungi that are propelled by flagella. (vedantu.com)
Pharmaceutical microbiology involves the use of various microbial species like actinomycetes, fungi, and protozoa for decomposing such waste materials and organic components. (pharmacyfreak.com)
In biology , a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. (oxygenboules824.sbs)
[ citation needed ] Spores form part of the life cycles of many plants , algae , fungi and protozoa . (oxygenboules824.sbs)
Spores of various algae, fungus, and protozoans are examples. (vedantu.com)
Zoospores are the asexual spore seen in some of the species like plants and algae. (vedantu.com)
Bacteria2
Owing in part to the inability of phages to attach to spores, seed banks stabilized population dynamics and resulted in minimum host densities that were 30-fold higher compared to bacteria that were unable to engage in dormancy. (nature.com)
A single teaspoon (1 gram) of rich garden soil can hold up to one billion bacteria, several yards of fungal filaments, several thousand protozoa, and scores of nematodes. (permaculturegardens.org)
Soil2
The first thing a seed develops in the germination process is a primary root that grows downward into the soil. (arizona.edu)
They produce flagellated, actively motile spores (zoospores) that are pathogenic to many crop plants and FISHES. (lookformedical.com)
Dispersal2
The spores of seed plants are produced internally, and the megaspores (formed within the ovules) and the microspores are involved in the formation of more complex structures that form the dispersal units, the seeds and pollen grains. (oxygenboules824.sbs)
The main difference between spores and seeds as dispersal units is that spores are unicellular, the first cell of a gametophyte, while seeds contain within them a developing embryo (the multicellular sporophyte of the next generation), produced by the fusion of the male gamete of the pollen tube with the female gamete formed by the megagametophyte within the ovule. (oxygenboules824.sbs)
Asexual reproduction1
The Asexual reproduction is accomplished by the fragmentation, fsomatic budding, fission, asexual spore formation. (microbiologynote.com)
Germinate3
In common parlance, the difference between a "spore" and a " gamete " is that a spore will germinate and develop into a sporeling , while a gamete needs to combine with another gamete to form a zygote before developing further. (oxygenboules824.sbs)
Spores germinate to give rise to haploid gametophytes, while seeds germinate to give rise to diploid sporophytes. (oxygenboules824.sbs)
To germinate, the spores require specific anaerobic conditions,[4] such as wounds with low oxidation-reduction potential (eg, dead or devitalized tissue, foreign body, active infection). (medscape.com)
Bacillus2
Since the colorless spores are located at one end of the bacillus, they cause the organism to resemble a turkey leg. (medscape.com)
A form of honey fungus found in the forests of Michigan, which began from a single spore and grows mainly underground, now is estimated to cover 40 acres. (permaculturegardens.org)
Plasmodium1
Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. (oxygenboules824.sbs)
Parasites2
Microsporidia are obligate, intracellular, spore-forming protozoal parasites. (powershow.com)
All microsporidia are obligate parasites with a life-cycle involving repeated proliferation by merogony, followed by sporogony, in which sporonts divide into two or more sporoblasts that mature into spores. (powershow.com)
Diploid1
In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte . (oxygenboules824.sbs)
Fragmentation1
i) budding (ii) spore formation (iii) regeneration and (iv) fragmentation. (assignmentsbag.com)
Narbonin amounts to up to 3% of the total seed globulins of mature seeds and was thought to be a storage protein but was found to degrade too slowly during germination. (unl.edu)
In some genera, sporonts produce sporoblasts by binary or multiple fission in direct contact with the host cell cytoplasm, so that the resultant spores are freely dispersed in the host cell. (powershow.com)
Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte , which eventually goes on to produce gametes. (oxygenboules824.sbs)
Useful ultrastructural details, provided by transmission electron microscopy , concern the appearance of mitochondria, properties of the septal pore , details of the cell wall during spore formation or germination, or the arrangement of secretory vesicles in the apex of growing hyphae. (istudy.pk)
During germination in a new host, the polar tube is evaginated and the sporoplasm (cytoplasm and nucleus) pass through it to be injected to the cytoplasm of a host cell. (powershow.com)
Plants1
Such plants typically give rise to the two kind of spores from within separate sporangia, either a megasporangium that produces megaspores or a microsporangium that produces microspores. (oxygenboules824.sbs)
Mature1
Spores are usually haploid and grow into mature haploid individuals through mitotic division of cells ( Urediniospores and Teliospores among rusts are dikaryotic). (oxygenboules824.sbs)
Process1
However, even though the alternative pathway generates less ATP, these fungicides are still effective in preventing spore germination, as this is an energy-intensive process. (wikipedia.org)
Form1
Unusually, the bloodstream form of the protozoan parasite Trypanosoma brucei, which is the cause of sleeping sickness, depends entirely on the alternative oxidase pathway for cellular respiration through its electron transport chain. (wikipedia.org)
In other genera, an envelope separates from the sporonts surface and division again by binary or multiple fission occurs within this envelope (sporophorous vesicle), resulting in packets of spores rather than free spores. (powershow.com)
