C-FERN® is a specially derived cultivar of an unusual fern,
Ceratopteris
, with novel features that make it ideal for classroom use. C-FERN® Classroom Kits are designed for use by up to 30 students working individually or in groups, depending on the exercise. Nearly all kits come complete with spores, petri dishes, special media, and detailed directions for students and instructors. For predictable results in C-FERN® gametophyte development, adequate lighting is necessary and can be provided by a simple fluorescent lighting fixture. A stereomicroscope is necessary for viewing the stages.
Spores are provided presterilized and preweighed in graduated vials. Students just add water, inoculate petri dishes containing C-FERN® Basic Medium, and maintain the dishes in culture domes that are a part of most kits. Cultures are grown under continous lighting and within an ideal temperature range of 28 to 30°C.
Spore germination and gametophyte development to sexual maturity, sexual reproduction, and early embryo development all take place within 14 days.
Two distinct investigations—carried out sequentially (2 kits in 1). Quantitatively explore the effects of population density. First, explore the influence density has on gametophyte sex ratio, and then, explore the effects of sporophyte competition. Includes materials for 30 students. Experiment time is 14 to 35 days. With instructions. Reusable with
