what takes over the function of photosynthesis in opuntia In the absence of leaves, enlarged stems carry out photosynthesis. what is a cactus? It is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. how did they evolve? Except for a relatively recent spread of "Rhipsalis baccifera" to parts of the Old World, cacti are plants of South America and mainly southern regions of North America. This suggests the family must have evolved after the ancient continent of Gondwana split into South America and Africa, which occurred during the Early Cretaceous. how do they reproduce? Cactus flowers are pollinated by insects, birds and bats. how are they classified? Botanists, such as Philip Miller in 1754, divided cacti into several genera, which, in 1789, Antoine Laurent de Jussieu placed in his newly created family Cactaceae. who is the former person mentioned? An English botanist of Scottish descent. and the latter? A French botanist. what was his heritage? The system of suprageneric nomenclature in botany is officially dated to 4 Aug 1789 with the publication of the Genera Plantarum (Gen. Pl.).

Antoine Laurent de Jussieu [SEP] Life
Jussieu was born in Lyon. He went to Paris to study medicine, graduating in 1770. He was professor of botany at the Jardin des Plantes from 1770 to 1826. His son Adrien-Henri also became a botanist. In his study of flowering plants, "Genera plantarum" (1789), Jussieu adopted a methodology based on the use of multiple characters to define groups, an idea derived from naturalist Michel Adanson. This was a significant improvement over the "artificial" system of Linnaeus, whose most popular work classified plants into classes and orders based on the number of stamens and pistils. Jussieu did keep Linnaeus' binomial nomenclature, resulting in a work that was far-reaching in its impact; many of the present-day plant families are still attributed to Jussieu.
