Many plants lose much of the remaining energy on growing roots. Most crop plants store ~0.25% to 0.5% of the sunlight in the product (corn kernels, potato starch, etc.). Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about ...
It flowers very profusely, [50] and the large flower heads are borne on stalks 5–9 cm (2–3.5 in) above the foliage. Unlike other forms, the stems wither and die naturally after flowering, making way for more new growth and flowers. [51] The flower heads are golden yellow and measure 6 cm (2.5 in) across. [7]
The seeds are yellowish light brown to nearly black in color and nearly round, 10–12 mm (0.4–0.5 in) long and 8–9 mm (0.3–0.4 in) wide. The seeds are quite buoyant. In an experiment they floated in water for a year and a half. [6] The leaves, flowers, and seeds are toxic to humans, cats, dogs, and livestock. [3]
Some moonflowers, which flower at night, are also in the morning glory family. Because of their fast growth, twining habit, attractive flowers, and tolerance for poor, dry soils, some morning glories are excellent vines for creating summer shade on building walls when trellised, thus keeping the building cooler and reducing heating and cooling ...
Cuscuta. Cuscuta (/ k ʌ s ˈ k juː t ə /), commonly known as dodder or amarbel, is a genus of over 201 species of yellow, orange, or red (rarely green) parasitic plants.Formerly treated as the only genus in the family Cuscutaceae, it now is accepted as belonging in the morning glory family, Convolvulaceae, on the basis of the work of the Angiosperm Phylogeny Group. [1]
These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), the rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying ...
With CMYK, color is produced as a function of the amplitude of the broad regions of absorption. Flowering plants by contrast produce color by modifying the frequency (or rather wavelength) of the light reflected. Most flowers absorb light in the blue to yellow region of the spectrum and reflect light from the green to red region of the spectrum.
Anthriscus sylvestris, known as cow parsley, [2] wild chervil, [2] wild beaked parsley, Queen Anne's lace or keck, [2] [3] is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae). [4] It is also sometimes called mother-die (especially in the UK), a name that is also applied to the common hawthorn. It is ...
