Extract the answer to the question from the following context. Question: What religion did blacks choose to identify with? Context: As early as the late 18th century, black Baptists began to organize separate churches, associations and mission agencies, especially in the northern states. Not only did blacks set up some independent congregations in the South before the American Civil War, freedmen quickly separated from white congregations and associations after the war. They wanted to be free of white supervision. In 1866 the Consolidated American Baptist Convention, formed from black Baptists of the South and West, helped southern associations set up black state conventions, which they did in Alabama, Arkansas, Virginia, North Carolina, and Kentucky. In 1880 black state conventions united in the national Foreign Mission Convention, to support black Baptist missionary work. Two other national black conventions were formed, and in 1895 they united as the National Baptist Convention. This organization later went through its own changes, spinning off other conventions. It is the largest black religious organization and the second largest Baptist organization in the world. Baptists are numerically most dominant in the Southeast. In 2007, the Pew Research Center's Religious Landscape Survey found that 45% of all African-Americans identify with Baptist denominations, with the vast majority of those being within the historically black tradition.

Extract the answer to the question from the following context. Question: Why where plants classified into 24 groups? Context: During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753 Carl von Linne (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's Systema Sexuale classified plants into 24 groups according to the number of their male sexual organs. The 24th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.
