Given the question: Information: - Wheat ("Triticum" spp., most commonly "T. aestivum") is a cereal grain (botanically, a type of fruit called a caryopsis), originally from the Levant region but now cultivated worldwide. In 2016, world production of wheat was 749 million tonnes, making it the second most-produced cereal after maize (1.03 billion tonnes), with more than rice (499 million tonnes). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st Century. - A planthopper is any insect in the infraorder Fulgoromorpha, exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and from the fact that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly so as not to attract attention. Distributed worldwide, all members of this group are plant-feeders, though surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista. - The femur (pl. "femurs" or "femora" ) or thigh bone, is the most proximal (closest to the hip joint) bone of the [leg] in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs. In vertebrates with four legs such as dogs and horses, the femur is found only in the hindlimbs. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the body. - Endosperm is a tissue produced inside the seeds of most of the flowering plants following fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in the human diet. For example, wheat endosperm is ground into flour for bread (the rest of the grain is included as well in whole wheat flour), while barley endosperm is the main source of sugars for beer production. Other examples of endosperm that forms the bulk of the edible portion are coconut "meat" and coconut "water", and corn. Some plants, such as orchids, lack endosperm in their seeds. - The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland. - Grasshoppers are insects of the suborder Caelifera within the order Orthoptera, which includes crickets and katydids (bush crickets). They are sometimes referred to as short-horned grasshoppers to distinguish them from the katydids, which have much longer antennae. They are probably the oldest living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which enable them to escape from threats by leaping vigorously. They are hemimetabolous insects (they do not undergo complete metamorphosis) which hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. At high population densities and under certain environmental conditions, some grasshopper species can change colour and behaviour and form swarms. Under these circumstances they are known as locusts. - The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweedbuckwheat family in the United States. The name is based on the genus "Polygonum", and was first used by Antoine Laurent de Jussieu in 1789 in his book, "Genera Plantarum". The name refers to the many swollen nodes the stems of some species have. It is derived from Greek; "poly" means many and "goni" means knee or joint. - The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia (tibiofemoral joint), and one between the femur and patella (patellofemoral joint). It is the largest joint in the human body. The knee is a modified hinge joint, which permits flexion and extension as well as slight internal and external rotation. The knee joint is vulnerable to injury and to the development of osteoarthritis. - A cereal is any grass cultivated for the edible components of its grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. Edible grains from other plant families, such as buckwheat (Polygonaceae), quinoa (Amaranthaceae) and chia (Lamiaceae), are referred to as pseudocereals. - Quinoa (from Quechua ' or ') is the common name for Chenopodium quinoa of the flowering plant family Amaranthaceae. It is grown as a grain crop primarily for its edible seeds. It is a pseudocereal rather than a true cereal, as it is not a grass. Quinoa is closely related to species such as beetroot and spinach and amaranth, another pseudocereal (which it closely resembles). After harvest, the seeds are processed to remove the coating containing the bitter-tasting saponins. Generally, the seeds are cooked the same way as rice and can be used in a wide range of dishes. The leaves, meanwhile, are sometimes eaten as a leaf vegetable, much like amaranth, but commercial availability of quinoa greens is limited. - Amaranthaceae is a family of flowering plants known as the amaranth family. It now includes the former goosefoot family Chenopodiaceae, and contains about 165 genera and 2,040 species. making it the most species-rich lineage within the flowering plant order of Caryophyllales. - Delphacidae is a family of planthoppers containing about 2000 species , distributed worldwide . Delphacids are separated from other '' hoppers '' by the prominent spur on the tibia of the hindleg . All species are phytophagous , many occurring on various grasses , and some are important vectors for cereal pathogens . The brown planthopper , Nilaparvata lugens ( Stal ) , is an example . - Lamiaceae (or ) or Labiatae is a family of flowering plants commonly known as the mint or deadnettle family. Many of the plants are aromatic in all parts and include widely used culinary herbs, such as basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage, such as "Coleus". Others are grown for seed, such as "Salvia hispanica" (chia), or for their edible tubers, such as "Plectranthus edulis", "Plectranthus esculentus", "Plectranthus rotundifolius", and "Stachys affinis" (Chinese artichoke). - Buckwheat ("Fagopyrum esculentum") is a plant cultivated for its grain-like seeds and as a cover crop. To distinguish it from a related species, "Fagopyrum tataricum", it is also known as Japanese buckwheat and silverhull buckwheat. - The fibula or calf bone is a leg bone located on the lateral side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and, in proportion to its length, the slenderest of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the level of the knee joint, and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia, and forms the lateral part of the ankle-joint. - The Auchenorrhyncha (former synonym: "Cicadinea") suborder of the Hemiptera contains most of the familiar members of what was called the Homoptera groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha. Lesser-known insects largely regarded as Homoptera are the Coleorrhyncha. However, the taxonomic status of the Hemiptera and Homoptera is currently under investigation and discussion. See Heteroptera and Prosorrhyncha for more information. - The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and viability of human body. - The tibia (plural tibiae or tibias), also known as the shinbone or shankbone, is the larger and stronger of the two bones in the leg below the knee in vertebrates (the other being the fibula), and it connects the knee with the ankle bones. The tibia is found on the medial side of the leg next to the fibula, and closer to the median plane or centre-line. The tibia is connected to the fibula by the interosseous membrane of the leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute "tibia". It is the second largest bone in the human body next to the femur. The leg bones are the strongest long bones as they support the rest of the body. - In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering. - Insects (from Latin ', a calque of Greek ['], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans.
