The rachis (pronounced /ˈreɪkɪs/) is the main axis of the inflorescence, or spike, of wheat and other cereals, to which the spikelets are attached. An inflorescence is a group or cluster of Flowers arranged on a stem that is composed of a main Branch or a complicated arrangement of branches Wheat ( Triticum spp is a worldwide cultivated grass from the Levant area of the Middle East. It is also the part of the axis that the pinnae are attached to in ferns, the main stem of a compound leaf (such as in Acacia), or the main axis in compound inflorescences in other angiosperms. A fern is any one of a group of about 20000 Species of Plants classified in the phylum or division Pteridophyta, also known as Filicophyta In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. Acacia is a Genus of Shrubs and Trees belonging to the Subfamily Mimosoideae of the family Fabaceae, first The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group

Spikelets are small inflorescences bearing one or more florets, or small flowers, along with a set of miniature bractlike leaves. A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. When the fruits of the wild-type wheat are fully ripened, a series of abscission layers forms that divides the rachis into dispersal units consisting of a single spikelet attached to a short segment of the rachis. The term fruit has different meanings dependent on context and the term is not synonymous in Food preparation and Biology. Réseaux IP Européens (RIPE French for "European IP Networks" is a forum open to all parties with an interest in the technical development of the Internet A ripe head of wheat is thus easily shattered into dispersal units when touched or blown by the wind. Wind is the flow of Air or other Gases that compose an Atmosphere (including but not limited to the Earth's) This is referred to by archaeologists as a "brittle rachis".
