How do plant hormones (often called plant growth regulators) travel between secreting cells and target cells?
Expert Solution & Answer
Summary Introduction
To explain: The way in which plant hormones travel between secreting cells and target cells.
Introduction: Plant hormones are chemical molecules or messengers produced in plants in response to their external stimuli. They are also known as “phytohormones”. It plays a major role in communication and co-ordination between the cells of plants also regulates the aspects of plant life including the growth and development.
Explanation of Solution
Plant hormones are signal molecules that regulate the plant processes. It acts as a messenger that travels throughout the plant and causes a specific physiological change in their target site. In plants, hormones travel between different parts through vascular tissue and even it travels in air as a gas to reach their target site. They also travel through plasmodesmata to communicate between cells.

Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites.
