Task: Question Answering
Input (English): Context: Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist or plant scientist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word ("botan") meaning "pasture", "grass", or "fodder"; is in turn derived from ("boskein"), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 400,000 species of living organisms of which some 260,000 species are vascular plants and about 248,000 are flowering plants., The bamboos are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering., In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world., Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., Lepidodendrales ( from Gr. `` scale tree '' ) were primitive , vascular , arborescent ( tree - like ) plants related to the lycopsids ( club mosses ) . They thrived during the Carboniferous period , and some reached heights of over 30 meters , with trunks often more than one meter in diameter . Sometimes called `` giant club mosses '' , they are in fact more closely related to quillworts than to club mosses ., A fern is a member of a group of about 10,560 known extant species of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having certain tissue that conducts water and nutrients. They have branched stems and leaves like other vascular plants. These are "megaphylls", which are more complex than the simple "microphylls" of clubmosses. Most ferns are Leptosporangiate ferns, sometimes denominated the "true ferns": they produce what are called "fiddleheads" that uncoil and expand into fronds., The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, Mya. The name "Carboniferous" means "coal-bearing" and derives from the Latin words "carb" ("coal") and "fer" ("I bear, I carry"), and was coined by geologists William Conybeare and William Phillips in 1822. Based on a study of the British rock succession, it was the first of the modern 'system' names to be employed, and reflects the fact that many coal beds were formed globally during that time. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian., In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth. If they do have secondary growth, it differs from the typical pattern of other seed plants., The banana is an edible fruit  botanically a berry  produced by several kinds of large herbaceous flowering plants in the genus "Musa". In some countries, bananas used for cooking may be called plantains, in contrast to dessert bananas. The fruit is variable in size, color and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind which may be green, yellow, red, purple, or brown when ripe. The fruits grow in clusters hanging from the top of the plant. Almost all modern edible parthenocarpic (seedless) bananas come from two wild species  "Musa acuminata" and "Musa balbisiana". The scientific names of most cultivated bananas are "Musa acuminata", "Musa balbisiana", and "Musa" × "paradisiaca" for the hybrid "Musa acuminata" × "M. balbisiana", depending on their genomic constitution. The old scientific name "Musa sapientum" is no longer used., Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae., Subject: lepidodendrales, Relation: taxon_rank, Options: (A) branch (B) division (C) family (D) genus (E) group (F) kingdom (G) order (H) section (I) species (J) subfamily
