Lettuce spaced farther apart receives more sunlight, which improves color and nutrient quantities in the leaves. Pale to white lettuce, such as the centers in some iceberg lettuce, contain few nutrients. [18] A transplanted bed of lettuce in a polytunnel. Lettuce grows best in full sun in loose, nitrogen-rich soils with a pH of
Using longer wavelengths means less light energy is needed for the same number of photons and therefore for the same amount of photosynthesis. For actual sunlight, where only 45% of the light is in the photosynthetically active wavelength range, the theoretical maximum efficiency of solar energy conversion is approximately 11%.
Inga edulis, known as ice-cream bean, ice-cream-bean, joaquiniquil, cuaniquil (both from Nahuatl: cuahuxinicuile combining cuahuitl "tree"; icxitl "feet" and necuilli "crooked" [2]) guama or guaba, is a fruit native to South America. It is in the mimosoid tribe of the legume family Fabaceae. [3]
Except for some parasitic plants, all land plants need sunlight to survive. [1] However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss.
This is a list of plants that have a culinary role as vegetables. "Vegetable" can be used in several senses, including culinary, botanical and legal. This list includes botanical fruits such as pumpkins, and does not include herbs, spices, cereals and most culinary fruits and culinary nuts.
The leaf is usually the primary site of photosynthesis in plants.. Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic.This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll.
