To identify:
The parallels in the properties and effects of epinephrine and the plant hormone auxin.
Introduction:
The organs of endocrine system release chemical signal as hormones. A hormone is released by the organ system when it receives an internal stimulus. The glands of endocrine system release their content directly into the blood circulation and regulate other organs of the body. They have no ducts and are called as ductless glands. The hormones of endocrine system are responsible for the regulation of body
The plants also produce hormones that play important role in the plant growth but their hormones are not secreted by glands. Their hormones are secreted by different cells in plant body. The plant hormone auxin is responsible for the growth of plants. Auxin promotes root initiation in plants.

- 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)arrow_forwardMAKE CONNECTIONS What examples of plantreproduction are most similar to asexual reproductionin animals? (See Concept 38.2.)arrow_forwardHi, Thanks in advance Explain in detail: the production of moult inhibiting hormone (MIH) from eyestalk and the mechanism of MIH in insects with example of mosquitoes. Be sure your answer includes the complete mechanism and complete diagram of mechanism.arrow_forward

(SeeFigures 11.15 and 11.16.)arrow_forwardWhat is the relevance of Pharmacognosy and Plant Chem to research and developement?arrow_forward
- Your concept map must include details about the following topics: types of stimuli plants respond to, 3 stages of cell signaling, 6 major plant hormones Six main types: Auxins, abscisic acid, cytokinins, ethylene gibberellin, and brassinosteroids. and their functions, phytochrome, plant responses to light, statocytes, statoliths, plant responses to gravity, plant responses to touch, plant defenses against herbivores, plant defenses against pathogens (hypersensitive response and systemic acquired resistance)arrow_forwardWhat is the first messenger in signal transduction? What are second messengers in signal transduction? What are the three results of signal transduction? What are three types of signaling processes based on their transduction distance? Give an example for each type. What are the signaling molecules in the plant? Please describe each of them briefly. How phytohormone degradation plays important roles in signaling pathways? Explain one of the phytohormones as an example. How plants respond to the environmental stimuli (biotic and abiotic stresses)? Please explain the amechanism and give an example.arrow_forwardWhich is the correct pairing of a plant hormone and its function? salicylic acid: triggers synthesis of general defense proteins brassinosteroids: promote responses to environmental stress cytokinins: stimulate stomata to close in water-stressed plants gibberellins: slow seed germination ethylene: promotes formation of lateral rootsarrow_forward
- Please help me with my hw. Tysm❤️ Instruction: Explain all answers in 5-6 sentences. Discussion: Discuss how feedback mechanism in plant physiology is affected by these hormones.arrow_forwardPlease type the answer to all parts of this question Answer the following question about the Quiescent Center (QC) of the root meristem. (a) What is the QC of the root meristem? (b) How is QC identity established? (Describe the plant hormone(s) and genes that are involved in QC development)arrow_forwardMAKE CONNECTIONS Plants use statoliths to detectgravity (see Figure 39.22). How do plants and animalsdiffer with regard to the type of compartment in whichstatoliths are found and the physiological mechanism fordetecting their response to gravity?arrow_forward
