Plant Water Regulation
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...
Growth and Plant Hormones
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...
