Stomach ulcer is an open sore appearing in the inner layer (mucosa) of the stomach, which causes dull or burning pain in the upper middle abdomen during or shortly after the meal; avoiding eating and losing weight may follow.
Auxins are a type of hormone, or growth substance, acquired from plants. Plant hormones are molecules manufactured by plants to accelerate, inhibit or modify its growth.In plants, growth occurs during cell division, cell elongation and cell differentiation.uxin, or indoleacetic acid (iaa), carries a very proficient relation to growth. It is in the midst of the most typical plant hormones and continues to be isolated from numerous plants. Studies with the response of plants to light, phototropism, are what led into the discovery and isolation of auxins.
Slide 2: Nature of Auxins The term auxin is derived from the Greek word auxein which means to grow. Compounds are generally considered auxins if they can be characterized by their ability to induce cell elongation in stems and otherwise resemble indoleacetic acid (the first auxin isolated) in physiological activity.ranslocation of Auxin Auxin travels from cell to cell being taken up on one side of the cell by influx transporters in the plasma membrane and moved out on the other side by efflux transporters-called PIN proteins-where it can then be taken up by the adjacent cell.
