Abstract
The processes of gamete fusion, zygote development, and zygote germination in Chlamydomonas moewusii are described. Light, previously shown to be essential for vegetative growth and for sexual activation, also appeared to be required for gamete fusion and for zygote maturation, but not for germination. Fully mature zygospores, enclosed in thick, impermeable walls, germinated erratically; experimental efforts to promote their earlier and more regular germination were unsuccessful. Germination as high as 60 to 90% was achieved by limiting the illumination which the zygotes received during their development.
