Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. Find out in this guide the importance of each hormone in the life of a plant...
Leaves are the major photosynthetic organ of a plant. Apart from that, they are also crucial to water movement. In this tutorial, various plant processes are considered in more detail. It also includes topics on leaf arrangements, leaf types, leaf structure, leaf color, abscission, and importance to humans...
In plants, growth occurs in meristems, which are the site of repeated cell division of unspecialized cells. These cells differentiate and become specialized in relation to the function they will perform. Learn more about plant meristems in this tutorial...
This tutorial deals with the structure and function of flowers, fruits, and seeds. Also included here are the types of fruits, fruit dispersal mechanisms, and seed germination. The distinctions between dicots and monocots, the two major groups of flowering plants, are presented in this tutorial...
The circulatory system is key to the transport of vital biomolecules and nutrients throughout the body. Learn about the different components and functions of the human circulatory system dealt with in detail in this tutorial. The lymphatic system is also elucidated elaborately here...
