Plant Writing

Name Professor Date Plant Writing Auxin This a hormone that is found in the stem, tips of roots and lateral buds which helps the stems to grow and extend while preventing the shooting of buds (Litwack 36-40). The hormone moves to darker areas of that cause the cells of the plant to become larger than those on the opposite side. Consequently, the plant bends one side. Auxin also maintains apical dominance in plants. It also helps in growing seeds to develop into fruits for instance in tomatoes. Cytokinins These hormones promote the division of cells. Cytokinins work together with Auxin to produce cell division in roots and fruits, embryo seeds and anywhere with growing tissues (Litwack 60-62). Corn is an example of a plant that uses cytokinins. They also help plants to develop new proteins that prevent them from aging. Hence, the hormone is sprayed to flowers to keep them fresh for a longer time. Gibberellins Gibberellins promote elongation of the stem (Theories Behind Plant Tissue Culture). Together with auxin, they also lead to the development of fruits. They facilitate the release of enzymes leading to the transfer of nutrients into endosperm. A growing embryo utilizes the nutrients to germinate
