Within a week or less, we should have available for free download the
current write-up for Chemical Attraction: C-Fern Sperm Chemotaxis. This

the ability of C-Fern sperm to detect and respond to a chemical signal
(positive chemotaxis). Using sperm from 12 – 18 day-old C-Fern
gametophyte cultures and simple equipment, students can document the
responses to a series of test solutions, including pairs of isomers that

chemoattractant that allows sperm to locate receptive archegonia and
