BIOLOGY REPORT: PLANT MINERAL DEFICIENCIES Objectives: To investigate the ashes of industrial plant mineral deficiencies. To develop problem solving and observational skills, for example, information is accurately processed, experimental procedures atomic number 18 planned, knowing and evaluated properly, and producing legitimate results and recording results. Introduction: A genus from free aimless aquatic plants from the duckweed family is called genus Lemna.Duckweed are small free floating plants practically forming tedious mats on the surface of still or slake forming water.In eutrophic(nutrients rich)water from cistron of organic enrichment from leaf litter,theLemna species grow the best.Lemna species are very much utilise as a model system for studies in association ecology,basic plant biology,exotoxicology, in production of biopharmaceutics, and as a source of animal feeds for agriculture and aquaculture.Lemna has small leaves with len gth 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 draw been classified as a interrupt 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 use for scrutiny toxicity of original chemicals. Lemna can be transform by molecular biologist to express proteins of pharmaceutical interest. putting 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 i s because the breakdown of chlorophyll a and! chlorophyll b (both green in colour) may reveal...If you want to get a undecomposed essay, order it on our website: BestEssayCheap.com
