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. [1] Spores form part of the life cycles of many plants , algae , fungi and protozoa . [ 2 ]
Spore is a 2008 life simulation real-time strategy god game developed by Maxis and published by Electronic Arts for Microsoft Windows and Mac OS X.Designed by Will Wright, it covers many genres including action, real-time strategy, and role-playing games.
Spore is a video game developed by Maxis and designed by Will Wright, released in September 2008.The game has drawn wide attention for its ability to simulate the development of a species on a galactic scope, using its innovation of user-guided evolution via the use of procedural generation for many of the components of the game, providing vast scope and open-ended gameplay.
Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves. The root system is always adventitious. The stem is either underground or ...
Spore-like cells, a specific class of stem cells; Spore print, a diagnostic character for identifying mushrooms; Resting spore, created by fungi; Milky spore, a bacterium of the white grubs of Japanese beetles; Bacterial morphological plasticity, bacteria changing into spores
In exosporic species, the smaller spores germinate into free-living male gametophytes and the larger spores germinate into free-living female gametophytes. In endosporic species, the gametophytes of both sexes are very highly reduced and contained within the spore wall. The microspores of both exosporic and endosporic species are free-sporing ...
Spore morphology is useful in distinguishing between different species. Spores of most species are oval or pyriform, but rod-shaped or spherical spores are not unusual. A few genera produce spores of unique shape for the genus. The spore is protected by a wall, consisting of three layers: an outer electron-dense exospore
Starting from a plant which disperses by spores, highly complex changes are needed to produce seeds. The sporophyte has two kinds of spore-forming organs or sporangia. One kind, the megasporangium, produces only a single large spore, a megaspore. This sporangium is surrounded by sheathing layers or integuments which form the seed coat.
