lant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is esponding the presence of light with the release of auxin. Auxin was first discovered for its ability to romote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of teral roots and root hairs.

Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. (b) Explain the role that auxin has in eliciting the plant’s response.

The summer is not optimal for grape growing and you're searching in your memory for something regarding plant hormones. Explain 2 ways you could utilize plant hormones (choose from auxin, ethylene, cytokinin, gibberellin, abscisic acid, salicylic acid, jasonic acid) to compensate for a problem during growing. For each way:
1. Plant Hormone signal transduction is an exciting field and the mode of signaling for various hormones in the cellular context have been elucidated. Compare and contrast the plant hormone Auxin and ethylene signal transductions mechanisms. (Hint. Begin at the Receptor level)
Many different treatments were possible in the phototropism experiment. Based on your understanding of phototropism, provide predictions about the direction of plant growth for the following two scenarios, and explain your reasoning. 1. The tip of the coleoptile is removed and lanolin with auxin is applied to the dark side of the stem. 2. The tip of the coleoptile is removed and lanolin with auxin is applied to the light side of the stem.
