Abstract

Sexual interaction in the unicellular green alga chlamydomonas eugametos comprises a number of steps in which the outer membrane of the cells is involved. In short, compatible gametes (i.e. of different mating type, mt+ and mt-) when mixed, agglutinate together via mobile receptors in the flagellar membrane. Next, the cells fuse by their ....

Results

'Cells in Space" module. One, (A. Tomson et al, University of Amsterdam, The Netherlands), investigated membrane functions during sexual reproduction in the green algae Chlamydomonas. Here, a comparison between flight and ground cells showed a 50% reduction in the activity of the flight cells right from the very start of the experiment. .... (full text)
