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.
Conifers (Coniferophyta). Conifers are the dominant phylum of gymnosperms, with the most variety of species ([link]). Most are typically tall trees that usually bear scale-like or needle-like leaves.Water evaporation from leaves is reduced by their thin shape and the thick cuticle.he layer of sporophyte tissue that surrounds the megasporangium, and later, the embryo, is called the integument. Gymnosperms were the dominant phylum in Mesozoic era. They are adapted to live where fresh water is scarce during part of the year, or in the nitrogen-poor soil of a bog.
