Time for a plant clinostat: effects of light and gravity on plants.
Science Activities, March, 2005 by Hershey, David R.
Abstract. Plant tropisms--their directional movement in response to stimuli--are a fundamental concept in plant science and excite students because they are the observable signs of life in plants. Unfortunately, the precollege teaching literature is full of tropism misconceptions. An inexpensive clock clinostat is invaluable for student gravitropism and phototropism experiments. It is also valuable for space biology experiments because a clinostat can mimic the microgravity of space.
Key words: gravitropism, hydrotropism, misconceptions, phototropism, plant physiology
**********
Plant tropisms are a common topic in precollege science teaching, but the teaching literature is filled with several misconceptions about tropisms. The term...
