The movement of molecules (specifically, water and solutes) is vital to the understanding of plant processes. This tutorial will be more or less a quick review of the various principles of water motion in reference to plants. ..
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...
Plants need to regulate water in order to stay upright and structurally stable. Find out the different evolutionary adaptations of plants in terms of structure (e.g. stomata) and physiological mechanisms (e.g. root pressure, capillarity, transpiration pull, curving of leaves, etc.) that enabled them to maintain the appropriate water level...
This study guide tackles plant roots in greater detail. It delves into the development of plant roots, the root structure, and the major regions of a plant root. It also talks about the different forms of roots that have specialized functions. ..
