Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation.Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant.This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.uxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant.

Tomcat implements several Java EE specifications including Java Servlet, JavaServer Pages (JSP), Java EL, and WebSocket, and provides a pure Java  HTTP web server environment for Java code to run in.omcat 4.x was released with Catalina (a servlet container), Coyote (an HTTP connector) and Jasper (a JSP engine).
Tomcat is an open-source project which provides the official reference implementation of the Java Server Pages (JSP) and Java Servlets technologies. In other words, Tomcat serves dynamic web content based on Java technology, and the way it does it is the way it should be done (for Java).Tomcat is just one of many tools in the Apache Software Foundation. Other useful tools are: 1  ant -- a Java-based software-build tool.ou create your JSP code or servlets, write some web pages in HTML to reference them, compile everything, deploy it to Tomcat (which encapsulates it in a container), and test it via a web browser. For general servlet development information, see the Application Developer's Guide.
