Flower differentiation is a plant process by which the shoot apical meristem changes its anatomy to generate a flower or inflorescence in lieu of other structures. Anatomical changes begin at the edge of the meristem, generating first the outer whorls of the flower - the calyx and the corolla, and later the inner whorls of the flower, the androecium and gynoecium.
It can be useful for flower identification or comparison between angiosperm taxa. Paleontologists can take advantage of diagrams for reconstruction of fossil flowers. Floral diagrams are also of didactic value. [1]: xiii Relation of a plant material (Campanula medium) to the floral diagram. Black dashed line shows the cross-section. 1 ...
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
Flower induction is the physiological process in the plant by which the shoot apical meristem becomes competent to develop flowers. Biochemical changes at the apex, particularly those caused by cytokinins , accompany this process. [ 1 ]
The single inflorescence grows extremely fast, and reaches 0.9–3 metres (3–10 ft) tall, bearing hundreds of elliptical (bell-shaped) white to purplish flowers 3 cm (1 + 1 ⁄ 4 in) in diameter on a densely branched panicle up to 70 cm (28 in) broad, covering the upper half of the inflorescence.
Orobanche uniflora, commonly known as one-flowered broomrape, [1] one-flowered cancer root, [2] ghost pipe [3] or naked broomrape, [4] is an annual [5] [6] parasitic herbaceous plant. It is native to much of North America, where it is a parasitic plant , tapping nutrients from many other species of plants, including those in the families ...
The opening to the flower is hairy. A highly variable plant, taking many forms, E. guttata is a species complex in that there is room to treat some of its forms as different species by some definitions. [9] The plant ranges from 10 to 80 centimetres (4 to 31 + 1 ⁄ 2 in) tall with disproportionately large, 2 to 4 cm long, tubular flowers. The ...
The titan arum (Amorphophallus titanum) is a flowering plant in the family Araceae. It has a large unbranched inflorescence; a tall single leaf, branched like a tree; and a heavy tuber which enables the plant to produce the inflorescence. A. titanum is endemic to rainforests on the Indonesian island of Sumatra.
