Bamboo is the world’s fastest growing plant thanks to the cell elongation process it shares with all grasses and its unique cell wall layering adaptation, allowing it to shoot up to 100 ft (30m) in just 8 weeks. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. ___________________________________________ To learn more, start your googling with these keywords: Rhizome: a continuously growing horizontal underground stem which puts out lateral shoots and roots at intervals Vacuole: an organelle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid, whose main purpose in plants is to maintain pressure against the cell wall Microfibrils: fiber-like strands consisting of glycoproteins and cellulose that make up the cell wall structure Auxin: a plant hormone which causes the elongation of cells in shoots and is involved in regulating plant growth ___________________________________________ If you liked this week’s video, you might also like: Fastest growing plant record - https://www.guinnessworldrecords.com/world-records/fastest-growing-plant Grass: An Introduction - https://lizzieharper.co.uk/2018/06/grass-an-introduction/ Bamboo Shoot Timelapse - https://www.youtube.com/watch?v=77Pgqf0rTbY _________________________________________ Subscribe to MinuteEarth on YouTube: http://goo.gl/EpIDGd Support us on Patreon: https://goo.gl/ZVgLQZ And visit our website: https://www.minuteearth.com/ Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC And download our videos on itunes: https://goo.gl/sfwS6n ___________________________________________ Credits (and Twitter handles): Video Narrator, Script Writer, and Co-Director: Julián Gustavo Gómez (@ittakesii) Script Editor: David Goldenberg (@dgoldenberg) Video Illustrator and Co-Director: Ever Salazar (@eversalazar) With Contributions From: Henry Reich, Alex Reich, Kate Yoshida, Peter Reich, Sarah Berman, Arcadi Garcia Rius Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder ___________________________________________ References: Velasquez, Silvia Melina, et al.
