LED LCD, OLED, and plasma. Of these current TV technologies, which one comes out on top? OLED is the new kid on the block, taking on LCD and plasma, the now elder statesmen of the TV world. OLED has the hype, LCD has the sales, and plasma as the adoration of most TV reviewers.
Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. 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.y contrast, gametes are units of sexual reproduction. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions.
With the exception of unicellular yeasts, the Ascomycetes are filamentous during development and their hyphae are septate (divided into cells). Reproduction is usually by the formation of specialized spores, called conidia, borne at the tips of hyphae in specialized structures (conidiophores).he word fungus usually evokes images of mushrooms and toadstools. Although mushrooms are fungi, the forms that a fungus may take are varied. There are over 100,000 species of described fungi and probably over 200,000 undescribed.
