Rationale. Specific leaf area is a ratio indicating how much leaf area a plant builds with a given amount of leaf biomass: where A is the area of a given leaf or all leaves of a plant, and M L is the dry mass of those leaves. Typical units are m 2 /kg or mm 2 /mg. Leaf mass per area (LMA) is its inverse and can mathematically be decomposed in ...
In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules; compound leaves may have a rachis supporting the leaflets. Leaf structure is described by several terms that include: [citation needed] Bipinnate leaf anatomy with labels showing alternative usages A ternate compound leaf with a petiole but no rachis (or ...

Rape Kale. [33][34] Brassica nigra. Black Mustard. Black mustard is commonly found in neglected gardens, on roadsides, in abandoned fields, and in areas where waste is disposed of. The plant is native to Asia and Europe, but now grows over much of southern Canada and almost all of the United States.
Maize (Zea mays, Poaceae) is the most widely cultivated C 4 plant.[1]In botany, C 4 carbon fixation is one of three known methods of photosynthesis used by plants. C 4 plants increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity.
Leaf margin. Rachis. A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [ 1 ] usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [ 2 ][ 3 ] while the leaves, stem, flower, and fruit collectively form the shoot system. [ 4 ]
Arabidopsis thaliana is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. [6] 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, and 2–10 mm broad, with an entire to coarsely serrated margin; the stem ...
