Seed leaf

I The distinction between mono-and dicotyledonous plants is quite simple monocotyledons are flowering plants which have only one seed leaf, and usually have parallel-veined leaves, flower parts in multiples of three, and no secondary growth in stems and roots, whereas dicotyledons are flowering plants with two seed leaves (cotyledons), net-veined leaves, flower parts in fours and fives, and in woody plants have cambium, a layer of formative cells between the wood and the bark the cells increase by division and differentiate to form new wood and bark. 

Seeds, leaf crops, and grasses are very efficient protein producers from the standpoint of amount per unit area. As indicated in Table IV, the more commonly used seeds and legumes, soybeans and wheat have relatively high protein production potentials (around 400 to 800 kg/ hectare). 

Histamine release from pig lung occurs in response to extracts from cotton pericarp, seed, leaf, root and bract (112). Extracts of sisal release histamine from both pig and human lung, but the reactivity is less than cotton dust extracts. The use of chopped lung for histamine assay is not always reliable, however, nor is it sufficiently sensitive.

Monocot— A plant whose embryo has a single cotyledon (seed leaf) and several other general characteristics. 

Lilies are the classic representatives of the monocotyledons—those plants with oily ore seed leaf. Lilies are mostly perennial, erect herbs arising from a bulb. Some climb, a few are woody, but most arise from underground stems or other stractures. The leaves vary in number from ore to many, and are arranged or the stem alternately or in whorls. The leaves are flat, linear to lance-shaped, without teeth along the margins, often widen into a papery sheath where they attach to the stem, lack stalks, and are typically parallel veined. 

The Embryo, consisting of a single shield-shaped cotyledon adjoining the endosperm, the plumule or rudimentary bud at the end of the caulicle or rudimentary stem and the radicle 6r rudimentary root, with its tip covered by a root cap. Continuous with the root cap is a root sheath or coleorhiza. The cotyledon or seed leaf consists of two parts the scutellum which lies next to the endosperm, and is an organ of absorption and the sheating portion which surrounds and protects the rest of the embryo. 

Monocotyled onous.—Having only one cotyledon or seed leaf. 

Iwamura (1984) designed a process for isolating saponins and flavonoids from leguminous plants, including seed, leaf, root, stem, stalk, flower or the entire plant. Alkaline extract, which was clarified by acid precipitation to get rid of proteins, followed by filtration or centrifugation, was applied to a nonpolar resin (styrene-vinyl benzene) or a slightly polar resin (such as acrylic ester resin). Water was used to elute soluble sugars, then the column was eluted with methanol to obtain a mixture of saponins and flavonoids. These two compounds were separated by acetone extraction to yield isoflavones in the soluble fraction.

Monocotyledoneae A class of flowering plants (seeANTHOPHYTA), distinguished by having one seed leaf ( cotyledon) within the seed. The monocotyledons generally have parallel leaf veins, scattered vascular bundles within the stems, and flower parts in threes or multiples of three. Monocotyledon species include some crop plants (e.g. cereals, onions, fodder grasses), ornamentals (e.g. tulips, orchids, lilies), and a very limited number of trees (e.g. the palms). Compare Dicotyledoneae eudicot.

Phytotoxicity testing can be conducted on two classes of flowering plants. These are monocots (plants with one seed leaf) and dicots (plants with two seed leaves). Representatives from both of these classes are typically used in toxicity testing - summer barley to represent monocots and cress to represent dicots. Test involves measuring the yield of both of these plants obtained from the test compost and from the control compost. 

Air borne spores produced fi om the stubble carry infection to young crops in the vicinity. Fungus spreads from the leaves to stem where cankers develop. The fungus can affect all parts of the plant including the seed. Leaf symptoms seen from Oct to April.
