Economic growth is an increase in real GDP. It means an increase in the value of goods and services produced in an economy. The rate of economic growth measures the annual percentage increase in real GDP.
Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive of a specific species and can therefore be used in identification of the species.
Many species of Ascomycota also (or exclusively) produce spores through an asexual or mitotic process; these spores, called conidia, exhibit a wide range of size, shape, color and septation among the different fungi in which they are formed.
