The combining of the genetic material carried by sperm and egg to create an embryo Normally occurs inside the fallopian tube (in vivo) by mas also occur in a petri dish (in vitro) See also In Vitro Fertilisation
The process in which the nuclei of a sperm and ovum join to make a new living thing
A term used to denote increased plant growth due to higher carbon dioxide concentrations, warmer temperatures or increased dispersion of nitrogenbased fertiliser
creation by the physical union of male and female gametes; of sperm and ova in an animal or pollen and ovule in a plant
The act of fecundating or impregnating animal or vegetable gametes; esp., the process by which in flowers the pollen renders the ovule fertile, or an analogous process in flowerless plants; fecundation; impregnation
The combining of the genetic material carried by sperm and egg to create an embryo Normally occurs inside the fallopian tube (in vivo) but may also occur in a petri dish (in vitro) See also In Vitro Fertilization
making fertile as by applying fertilizer or manure creation by the physical union of male and female gametes; of sperm and ova in an animal or pollen and ovule in a plant
1 In floral biology, the union of male and female gametes to produce a fertilized egg cell 2 In agriculture, the practice of adding nutrients to soil or plants for use by plants
Reproductive process in which a male sex cell (sperm) unites with a female sex cell (egg). During the process, the chromosomes of the egg and sperm will merge to form a zygote, which will divide to form an embryo. In humans, sperm travel from the vagina through the uterus to a fallopian tube, where they surround an egg released from an ovary usually two or three days earlier. Once one sperm has fused with the egg cell membrane, the outer layer becomes impenetrable to other sperm. See also cross-fertilization, self-fertilization. cross fertilization in vitro fertilization self fertilization
The addition of fertilizer to promote tree growth on sites deficient in one or more soil nutrients Also used to improve the vigour of crop trees following juvenile spacing or commercial thinning
A term used to denote efforts to enhance plant growth by increased application of nitrogen-based fertilizer or increased deposition of nitrates in precipitation
the addition of fertilizer to promote tree growth on sites deficient in one or more soil nutrients Also used to improve the vigor of crop trees following juvenile spacing or commercial thinning
The addition of fertilizer to promote tree growth on sites deficient in one or more soil nutrient elements Also used to improve the vigor of crop trees following juvenile spacing or commercial thinning
the union of the ovum of a female with the male's spermatozoon (the male sex cell carried in the seminal discharge) resulting in the initiation of the development of a new individual
The act of fecundating or impregnating animal or vegetable germs; esp., the process by which in flowers the pollen renders the ovule fertile, or an analogous process in flowerless plants; fecundation; impregnation
