fertilization

Allogamy Cross-fertilization in plants.

The pattern of the fertilization of turbot is monospermy, which is similar with that of flounder.

Fertilization is external, producing free-living planula larva.

Traditionally, doctors use gestational age, the number of weeks from fertilization to birth, to determine whether a preemie should receive invasive care.

chalazogamy A method of fertilization in angiosperms in which the pollen tube enters the ovule by the chalaza instead of through the micropyle, penetrating the placenta en route.

We focused on several key events during fertilization from membrane fusion to karyogamy of sperm cells and egg cells.

A long-term field experiment was carried out to study the effect of fertilization on the organo-mineral complexation and the combined forms of humus of phaeozem in Jilin Province, China.
