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 ]
These adaptations enable it to occupy niches too harsh for vascular plants or mosses, reducing competition in these environments. [17] The podetia show a high degree of variability, ranging from entirely decorticate surfaces to densely squamulose ones, allowing the lichen to adapt to a wide range of environmental conditions and substrate types.
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.
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.
A rust spore typically germinates on a plant surface, growing a short hypha called a germ tube. This germ tube may locate a stoma by a touch responsive process known as thigmotropism . This involves orienting to ridges created by epidermal cells on the leaf surface, and growing directionally until it encounters a stoma.
Fruiting bodies have a short stalk from which arises a spore-bearing structure (the receptaculum) of 5–8 arched arms. These arms, initially joined at the top, disconnect and curve irregularly to expose the inner surface of each arm, which is covered with green spore-containing gleba. Spores are 3–4 × 1–1.5 μm.

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
Elevation of the sporulating head atop a long stalk above the growing surface may facilitate spore dispersal through the air. [17] Normally, spores in fungi are discharged into still air, but in A. terreus, it resolves this problem with a long stalk and it allows the spores to discharge into air currents like wind. [18]
