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.
Light is a stimulus that plants respond to. This is called phototropism (photo= light). Plants usually display a positive phototropic response to light, which means they grow toward a light source. Plant hormones called auxins play a part in phototropism.Auxin is a plant growth hormone. When light is shined on one side of a plant the auxins move to the dark side of the plant.The hormones stimulate the cells on the dark side of the plant to elongate, while the cells on the light side of the plant remain the same.ight is a stimulus that plants respond to.
