To determine:
The response of the lateral buds if an individual removed a plant’s shoot apical meristem and applied auxin to the cut surface.
Introduction:
The size of the shoot and root systems of plants must be in balance so as the roots grow, the shoots also grow enough to support the plant. Auxin produced by apical meristem of shoot and Cytokinin by apical meristem of roots promote this balance.
To explain:
The response of the lateral buds if an individual removed a plant’s shoot apical meristem and applied auxin to the cut surface.
Introduction:
The plant hormones also called as phytohormones are chemical substances secreted by specific cells that regulate the growth of plants. Various plant hormones influence many aspect of life cycle of plant by altering the expression of gene.

- Auxin, like many substances, can be transported through the phloem; however, there is a second mechanism that exists just for auxin transport. What is it?arrow_forwardPlant 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.arrow_forwardHow does the signal transduction pathway for auxin that leads to cell wall loosening. Include the receptors ABP and ARF. How does the auxin pathway possibly differ from the 'generic' signal transduction pathway? Consider expressing the cellular components that differ in the absence and presence of auxin.arrow_forward
- If auxin transport proteins were equally distributed at both ends of the cells, would polar auxin transport still be possible? Explain.arrow_forwardWhy a flower is emascuated and auxin is applied to its stigma?arrow_forwardHow is the plant able to detect which way is up and which way is down?arrow_forward
- Is it true that in the gravitropic response of horizontal roots, high auxin concentration on the upper side impede growth while decreased auxin level on the lower side stimulates growth?arrow_forwardThe 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:arrow_forwardD2)arrow_forward
- 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. a) Describe the plant’s response to the presence of light. (refer to picture)arrow_forwardDescribe how auxin causes a plant to bend towardlight.arrow_forwardWhich of the following statements is false? a. Auxin and gibberellin promote stem elongation b. Cytokinin promotes cell division in shoot tips c. Abscisic acid promotes water loss and dormancy d. Ethylene promotes fruit ripening and abscission.arrow_forward
