Lemna Coursework Introduction Lemna are small water plants found in ponds. Typical of plants, they reproduce asexually. When they reproduce they form a bud on the edge of a leaf, which, when big enough, will eventually separate from the mother leaf and can then reproduce itself. Sometimes lemna plants can have up to 3 or 4 buds. Exactly the same as plants in soil, they use the sun's energy for photosynthesis, and water, but they have to take all their nutrition to grow and reproduce
Introduction Duckweeds are small aquatic plants that float on the surface on bodies of water. One plant has a leaf-like structure with a root under the plant. The diameter of a leaf is usually not more than 0.5 cm (Duckweed). The water in its habitat has to be slow-moving or still, no faster than 0.3 m/second. Therefore they grow in areas that are protected from wind and waves. The water has to be nutrient-rich and fresh or brackish. They can be found in many places in the world as they can live
Part A: Introduction: Common name : Duckweed (Duck Weed) Latin name : Spirodela; Landoltia; Lemna; Wolffiella; Wolffia Family name : Araceae Common duckweed is a very small light green free-floating, seed bearing plant. Duckweed has 1 to 3 leaves, or fronds, of 1/16 to 1/8 inch in length. A single root (or root-hair) protrudes from each frond. Duckweeds tend to grow in dense colonies in quiet water, undisturbed by wave action. A lot of the time more than one species of duckweed will be growing
Introduction The aim of the following experiment is to determine the correlation between the level of nitrates in the water and the growth of duckweed. It is expected that the increased amount of nitrates in the water will cause the duckweed to grow. The duckweed is expected to absorb the nitrates as it grows and therefore lower the levels of nitrates in the water. This is a valid aim as the results could be used as a method of deterring and removing eutrophication in bodies of water where other
Aims and Scope: Nowadays, nanotechnology is used in many different sciences. Plants are no exception. Therefore, we decided to study the beneficial effect of titanium dioxide and titanium dioxide nanoparticles phytotoxicity on some physiological characteristics of Melissa officinalis plant including germination, root length, shoot length, and photosynthetic pigments. The experiment was conducted in 2013 in the Research Laboratory of Islamic Azad University of Falavarjan, Isfahan, Iran. Methodology:
The Influence of Light on Chloroplast Development and Movement Light is an important regulator of both chloroplast development and chloroplast movement in plants. In terms of chloroplast development, light regulates the biogenesis of the photosynthetic apparatus in chloroplasts and the adaptation of that apparatus to the environment so as to maximise photosynthesis. In terms of chloroplast movement, weak light induces chloroplasts to undergo accumulation movement, while strong light induces
