Objectives:
To investigate the frame of industrial plant mineral deficiencies. To develop problem solving and observational skills, for example, information is accurately processed, experimental procedures are planned, designed and evaluated properly, and producing legitimate results and recording results.
Introduction:
A genus from free floating aquatic plants from the duckweed family is called Lemna.Duckweed are small free floating plants often forming tedious mats on the surface of still or slow forming water.In eutrophic(nutrients rich)water from cistron of organic enrichment from leaf litter,theLemna species grow the best.Lemna species are often utilise as a model system for studies in association ecology,basic plant biology,exotoxicology, in production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture.Lemna has small leaves with length of 5 mm except for spirodelapolyrhiza which can be up to 1 cm, all single (Lemnaminuta and Lemnagibba) or in groups of two or ternion (Lemna minor).The duckweeds have been classified as a separate family,theLemnaceae and Araceae.
Lemnatrisulca is linear and has a branched structure while Lemnathalli have a single root, which distinguishes them from related genera Spirodelaand Landoltia.
The diagram 1 shows: the Lemna plant with its root.
Lemna is a genus of free-floating aquatic plants from the duckweed family. Lemna are small, free-floating aquatic water plants found in ponds. Lemna has been used for scrutiny toxicity of certain chemicals. Lemna can be transform by molecular biologist to express proteins of pharmaceutical interest. greensickness (break down of chlorophyll) happens when a plant deprived of certain nutrients such(prenominal) as nitrogen, magnesium, and iron. Chlorosis can be noted by yellowing and decolourising of the leaves. This is because the breakdown of chlorophyll a and chlorophyll b (both green in colour) may reveal...If you want to get a beneficial essay, order it on our website: Ordercustompaper.com
