- Abstract
The article discusses the effects of light on plant development and use the spores of the sensitive fern, Onoclea sensibilis, in laboratory exercises to demonstrate key concepts in plant science and biology. In terms of the scientific conclusions, these exercises demonstrate that light quality has an impact on the development of fern gametophytes. Light is necessary for germination in Onoclea spores. Blue and white light is required to induce two-dimensional growth in Onoclea gametophytes. Gametophytes remain filamentous in red light. Teachers can also use these exercises to discuss the nature of light and point out that white light consists of component colors which can be separated with a prism.
