Exempel på hur man kan använda SPORE i en mening

• It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes.
• A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms.
• 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.
• In junipers (the primary hosts, see photo), some species form a ball-like gall about 2–4 cm in diameter which produces a set of orange tentacle-like spore tubes called telial horns.
• Humans have colonized the planet Pern in the Rukbat star system, but have lost much of their technology and history (including their origin on Earth) due to periodic onslaughts of Thread, a mycorrhizoid spore that voraciously consumes all organic material, including humans and their crops, given the opportunity.
• The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.
• An ergot kernel, called a sclerotium, develops when a spore of fungal species of the genus Claviceps infects a floret of flowering grass or cereal.
• The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath.
• They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum.
• The average size of a myxosporean spore usually ranges from 10 μm to 20 μm, whereas that of a malacosporean (a subclade of the Myxozoa) spore can be up to 2 mm.
• Ward also kept cocoons of moths and the like in sealed glass bottles, and in one, he found that a fern spore and a species of grass had germinated and were growing in a bit of soil.
• Although presence of the conidial phase on the spore mats is known, the function of the conidia remains unknown since conidial germination is rarely observed.
• Fairy rings are detectable by sporocarps (fungal spore pods) in rings or arcs, as well as by a necrotic zone (dead grass), or a ring of dark green grass.
• One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases.
• Salviniales are all aquatic and differ from all other ferns in being heterosporous, meaning that they produce two different types of spore (megaspores and microspores) that develop into two different types of gametophyte (female and male gametophytes, respectively), and in that their gametophytes are endosporic, meaning that they never grow outside the spore wall and cannot become larger than the spores that produced them.
• Germ pore, a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination.
• The spore print is white, the spores (under a microscope) smooth, inamyloid, ellipsoid to cylindrical, c.
• While these radiometric dating measurements place the Boltysh crater hundreds of thousands of years after the Chicxulub crater, a 2010 radiometric and palynological study of fern spore (fern spikes) abundance suggested the Boltysh impact may have occurred several thousand years before Chicxulub.
• In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: Leucocoprineae, Agariceae, Lepioteae, and Cystodermateae.
• In mosses, the peristome is a specialized structure in the sporangium that allows for gradual spore discharge, instead of releasing them all at once.
