Heteroblastic
Heteroblasty is the significant and abrupt change in form and function, that occurs over the lifespan of certain plants. Characteristics affected include internode length and stem structure as well as leaf form, size and arrangement. It should not be confused with seasonal heterophylly, where early and late growth in a season are visibly different. This change is different from a homoblastic change which is a gradual change or little change at all, so that there is little difference between the juvenile and adult stages. Some characteristics affected by heteroblastic change include the distance between successive leaves (internode length) and stem structure as well as leaf form, size and arrangement. Heteroblasty is found in many plant families as well as only some species within a genus. This random spread of heteroblastic plants across species is believed to be caused by convergent evolution. The earlier and later stages of development are commonly labeled as juvenile and adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pseudopanax Crassifolius
''Pseudopanax crassifolius'', also known as horoeka or lancewood, is a Heteroblasty, heteroblastic tree belonging to the family Araliaceae. It is Endemism, endemic to New Zealand and found throughout the country from sea level up to about in lowland to montane shrublands and forests. The juvenile form, which lasts between 15 and 20 years, is easily recognised. The leaves are stiff and leathery with a prominent central rib, about 1 cm wide and up to 1 m long with irregular teeth, all growing downwards from a central stem. The young trunk has characteristic vertical swollen ridges. As the tree gets older the stem begins to branch, producing a bushy top. The leaves also become wider and shorter, losing their teeth. It is only when the tree is mature that it adopts a typical tree shape. The difference between the juvenile and adult tree's appearance is so drastic that the two forms were initially described as separate species and even genera by early botanists, including ...

Hedera Helix
''Hedera helix'', the common ivy, European ivy, King's Choice ivy, or just ivy, is a species of flowering plant in the family Araliaceae. It is native to most of Europe and parts of western Asia. Ivy is a clinging evergreen vine that grows on tree trunks, walls, and fences in gardens, waste spaces, and wild habitats. Ivy is popular as an ornamental plant, but escaped plants have become naturalised outside its native range. Ivy has considerable cultural significance and symbolism. Synonyms include ''Hedera acuta'', ''Hedera arborea'' ('tree ivy'), ''Hedera baccifera'', and ''Hedera grandifolia.'' Other common names are bindwood and lovestone. Description ''Hedera helix'' is an evergreen climbing plant, growing to high where suitable surfaces (trees, cliffs, walls) are available, and also growing as groundcover where no vertical surfaces occur. It climbs by means of aerial rootlets with matted pads which cling strongly to the substrate. The ability to climb on surfaces varies w ...

Zea Mays
Maize (; ''Zea mays''), also known as corn in North American English, is a tall stout Poaceae, grass that produces cereal grain. It was domesticated by indigenous peoples of Mexico, indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and Cucurbita, squashes in the Three Sisters (agriculture), Three Sisters polyculture. The leafy Plant stem, stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ear (botany), ears. The ears yield grain, known as Corn kernels, kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange, it has become a staple food in many parts of the world, with the List of most valuable crops and livestock products, total production of maize surpassing that of wheat and rice.

Snapdragon
''Antirrhinum'' is a genus of plants in the Plantaginaceae family, commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are also sometimes called toadflax or dog flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa. ''Antirrhinum'' species are widely used as ornamental plants in borders and as cut flowers. Description The ''Antirrhinum'' is morphologically diverse, particularly the New World group (''Saerorhinum''). The genus is characterized by personate flowers with an inferior gibbous corolla. Taxonomy ''Antirrhinum'' used to be treated within the family Scrophulariaceae, but studies of DNA sequences have led to its inclusion in a vastly enlarged family Plantaginaceae, within the tribe Antirrhineae. Circumscription The taxonomy of this genus is complex and not yet fully resolved at present. In particul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Antirrhinum Majus
''Antirrhinum majus'', the common snapdragon (often – especially in horticulture – simply "snapdragon"), is a species of flowering plant belonging to the genus ''Antirrhinum''. The plant was placed in the family Plantaginaceae following a revision of its prior classical family, Scrophulariaceae. The common name "snapdragon", originates from the flowers' reaction to having their throats squeezed, which causes the "mouth" of the flower to snap open like a dragon's mouth. It is widely used as an ornamental plant in borders and as a cut flower. It is perennial but usually cultivated as an annual plant. The species has been in culture since the 15th century. Description It is an herbaceous perennial plant, growing to 0.5–1 m tall, rarely up to 2 m. The leaves are spirally arranged, broadly lanceolate, 1–7 cm long and 2–2.5 cm broad. The upper glandular stalk is stalk-round, sometimes woody to the middle. The opposite leaves are simple, elliptic or ovate to br ...

Mouse-Ear Cress
''Arabidopsis thaliana'', the thale cress, mouse-ear cress or arabidopsis, is a small plant from the mustard family (Brassicaceae), native to Eurasia and Africa. Commonly found along the shoulders of roads and in disturbed land, it is generally considered a weed. A winter annual with a relatively short lifecycle, ''A. thaliana'' is a popular model organism in plant biology and genetics. For a complex multicellular eukaryote, ''A. thaliana'' has a relatively small genome of around 135 megabase pairs. It was the first plant to have its genome sequenced, and is an important tool for understanding the molecular biology of many plant traits, including flower development and light sensing. Description ''Arabidopsis thaliana'' is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem. The basal leaves are green to slightly purplish in color, 1.5–5 cm long, ...
