More videos from the collection at the following link: http://bit.ly/1cwwYkV Prác009 Effect of light and darkness on the growth of seedlings. Subject: Plant Physiology. Degree in Experimental Sciences. Professor: María Asunción Amorós Marco. Department of Applied Biology. Area of ​​Plant Physiology. Miguel Hernández University of Elche. Seedlings grow differently if they are growing in the light or if they are growing in the dark, since light stimulates the development of the leaves, the development of the chloroplasts and the synthesis of chlorophyll, but inhibits the development of the stem. These effects of light on the development of plants are mediated by a protein plant pigment known as phytochrome. In this video we will check the different way that etiolated plants (grown in the dark) grow compared to plants grown in the light. subject web: http://umh2248.edu.umh.es web: http://umh.es
