Investigate Biology With C-Fern

  • For grades 7 - 12 and college-level biology

  • Simple and rapid set up by teacher or students

  • Explore a broad spectrum of biological principles

  • Introduces simple, failproof axenic culture techniques

  • Adaptable - from teacher demonstrations to student initiated learning

  • Rapid gametophyte development from spores over a 14 day period

  • Watch the release of swimming sperm and their attraction to eggs under a stereomicroscope.

  • Visualize fertilization and early embryo development, all in a single petri dish

  • Two distinct sexual types - hermaphrodites and males

  • Simple genetics with striking visible mutant phenotypes - e.g., polka dot

  • Spore to spore life cycle in as little as 90 days. Sporophytes are long-lived , highly fertile, have a sturdy upright growth habit and produce spores with no after-ripening requirement

The C-Fern Manual and C-Fern Educational Investigations have been developed jointly by Drs. Leslie G. Hickok and Thomas R. Warne (The University of Tennessee) with support from the National Science Foundation - Division of Undergraduate Education. The C-Fern is a specially derived strain of an unusual fern, Ceratopteris, with novel features that make it ideal for classroom use.
