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...
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...
Seed plants are vascular plants. They differ from the other vascular plants in producing seeds that germinate into a new plant. Two major plant divisions are covered: the angiosperms and the gymnosperms. ..
Learn about community patterns and the ecological factors influencing these patterns. Revisit some of the ecosystems you've learned about earlier to learn more about the possible impacts of natural and human-induced environmental changes...
