Dickel and others have lately claimed that fertilized eggs can give rise to either queens, workers or males, according to the food supplied to the larvae and the influence of supposed "sex-producing glands" possessed by the nurse-workers.

Weismann, however, doubts these conclusions, and having found a spermaster in every one of the eggs that he examined from workercells, and in only one out of 272 eggs taken from drone-cells, he supports Dzierzon's view, explaining the single exception mentioned above as a mistake of the queen, she having laid inadvertently this single fertilized egg in a drone instead of in a worker cell.

It is believed that from the nature of the cell in which she is ovipositing, the queen derives a reflex impulse to lay the appropriate egg - fertilized in the queen or worker cell, unfertilized in the drone cell, as previously mentioned.

It may be regarded as derived from a wholly dependent sporogonium not unlike that of some of the simpler Bryophyta; the latter are assumed to have arisen from primitive Algal forms, in which, as the first step in the interpolation of the second generation in the life cycle, the fertilized ovum gave rise to a group of swarm spores, each of which developed into a new sexual plant.

On this view the origin of the sporophyte is looked for in the gradual development of sterile tissue in the generation arising from the fertilized ovum, and a consequent postponement of spore-formation.

The Archegoniatae are characterized by a well-marked alternation of gametophyte and sporophyte generations; the former bears the sexual organs which are of characteristic structure and known as antheridia (male) and archegonia (female) respectively; the fertilized egg-cell on germination gives rise to the spore-bearing generation, and the spores on germination give rise directly or indirectly to a second gametophyte.

They are attracted to the flower by its colour or its perfume; they seek, collect or feed on its honey, and while so doing they remove the pollen from the anther and convey it to another flower, there to germinate on the stigma when its tubes travel down the style to the ovary where their contents ultimately fuse with the "oosphere" or immature egg, which becomes in consequence fertilized, and forms a seed which afterwards develops into a new plant (see article Angiosperms).

Implantation-The process in which the fertilized egg embeds itself in the wall of the uterus.

If the ovum is fertilized by a sperm at this time, pregnancy occurs.

However, if a sperm does not fertilize the egg, the body no longer needs the uterine lining to support the fertilized egg.

Then the fertilized egg must travel to the woman's uterus (womb), where it lodges in the uterus lining and develops into a fetus.

Eggs that do not ripen fully cannot be fertilized.

Oral contraceptives also change the uterine lining so that a fertilized egg cannot lodge there to develop.

When an egg is fertilized, it travels through the fallopian tubes where it implants into the uterus.

In an ectopic pregnancy the fertilized egg implants into a place other than the uterus.

Additionally, because eggs can be fertilized for 24 hours after release, the day after ovulation is still considered a fertile time.

Without hormones, a normal, healthy woman will release an egg once a month, and her uterus will build up a thick, blood-rich lining to receive the egg in case it gets fertilized by a man's sperm.

Endometriosis may lead to scarring; if the fallopian tubes become scarred from the implants, the egg may not be able to travel through them to get fertilized.

The secretion of LH is what causes the most mature follicle in the ovary to burst and release a egg that is ready to be fertilized.

Ovulation occurs midway between menstrual cycles and is the process when the egg leaves the fallopian tube and travels to the uterus to get fertilized by the male's sperm.

The egg lives approximately 24 hours and must be fertilized during this time or pregnancy won't occur.

A male sperm lives approximately 72 hours inside the woman waiting for an egg to be fertilized.

Damage to the fallopian tubes can prevent the fertilized egg from traveling down the tube and into the uterus.

The hormone changes the environment of the uterus; sperm is unable to enter the cervix and a fertilized egg cannot implant in the uterine wall.

The copper is gradually released into the uterus, immobilizing sperm and blocking implantation of fertilized eggs.

Since the egg is unable to travel down the fallopian tubes, they can't make their way to the uterus and they can't get fertilized.

When your ovaries release a fertile egg during ovulation, it is typically only available to be fertilized for about one day, or around 12 to 24 hours.

When a fertilized egg implants itself into the blood lining of the uterus, some women experience mild cramping.

The offspring of the virgin females are in most of these instances females; but among the bees and wasps parthenogenesis occurs normally and always results in the development of males, the " queen " insect laying either a fertilized or unfertilized egg at will.

The segmentation of the fertilized nucleus results in the formation of a number of nuclei which arrange themselves around the periphery of the egg and, the protoplasm surrounding them becoming constricted, a blastoderm or layer of cells, enclosing the central yolk, is formed.
