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 metabolism and growth. Adrenal glandis an endocrine gland that is found above the kidney and release epinephrine hormone. These hormones are released during the fight or flight response. 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.

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 metabolism and growth. Adrenal glandis an endocrine gland that is found above the kidney and release epinephrine hormone. These hormones are released during the fight or flight response.

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.

Hormones and signal pathways Complete the following paragraph to describe signal transduction as it occurs within plants. Choices may be used more than once or not at all. Chemical signals called play an important role in a plant's ability to respond to a stimulus. These signals bind to receptors, the first step in a cellular response called a may be located in the plasma membrane, the cytoplasm, the nucleus, or the endoplasmic reticulum. The series of relay proteins or enzymes activated by the hormone binding the receptor make up the Some responses are immediate, while others require a like Ca*, to initiate a cellular response. The result of the transduction pathway is a which is often the transcription of specific genes, resulting in some measurable change. hormones reflex arc signal transduction pathway Signal transducers second messenger response Receptor proteins first messenger

What 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.

1. A) Describe the three steps (Reception, Transduction, Response) of de-etiolation (greening response) signal transduction in plants. B) Describe a signal transduction (give the stimulus and response) that may occur in humans.
