What is the significance of this rather wasteful type of gamete production that is production of a single functional gamete instead of four as seen in males?

What is the significance of this rather wasteful type of gamete production that is production of a single functional gamete instead of four as seen in males?

What is the significance of this rather wasteful type of gamete production, that is, production of a single functional gamete instead of four, as seen in males? Oogenesis produces three tiny polar bodies, nearly devoid of cytoplasm, products of unequal division of gametes during meiosis.

Which of the following is a characteristic of the head of a sperm?

The head of the sperm contains the DNA, which when combined with the egg’s DNA, will create a new individual. The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg. The midpiece contains the mitochondria which supplies the energy the tail needs to move.

What structures draw an ovulated oocyte into the female duct system?

22 Cards in this Set

The structures that draw an ovulated oocyte into the female duct system are…….	Cilia and Fimbriae
The sex of the child is determined by A) The sex chromosome contained in the oocyte, B) the sex chromosome contained in the sperm.	B) The sex chromosome contained in the sperm.

Why is the menstrual cycle so important quizlet?

Why is the menstrual cycle so important? It is important because it makes having a baby possible. Define menopause.

What is the function of the enzymes located in the acrosome quizlet?

Where is the acrosome located, and what is its function? The head, contains enzymes to help sperm penetrate female gametes.

Why are sperm cells provided with more mitochondria?

There is a region that contains enzymes to help the sperm cell penetrate the surface of the egg. The sperm’s midpiece contains many mitochondria so that a supply of energy is available for the sperm to perform its function of traveling to and later fertilizing the egg.

Where is the sperm at Oogenesis occur in?

the ovaries
Oogenesis occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo.

Which structures help direct the ovulated oocyte into the uterine tube?

The ovulated oocyte with its surrounding granulosa cells is picked up by the infundibulum of the uterine tube, and beating cilia help to transport it through the tube toward the uterus. Fertilization occurs within the uterine tube, and the final stage of meiosis is completed.

What is period blood called?

Menstrual fluid is the correct name for the flow, although many people prefer to refer to it as menstrual blood. Menstrual fluid is reddish-brown, a slightly darker color than venous blood.

In which structure of the male reproductive system does spermatogenesis occur?

the testes
spermatogenesis, the origin and development of the sperm cells within the male reproductive organs, the testes. The testes are composed of numerous thin tightly coiled tubules known as the seminiferous tubules; the sperm cells are produced within the walls of the tubules.

Where is the urogenital opening in a male?

In males, the urogenital structures consist of the penis (which has an opening just behind the umbilical cord)and two sac-like swellings called the scrotum, containing the testes. Where is the urogenital opening?

Is the uretha part of the reproductive system?

Because the Uretha does not play a part in the reproductive system of females nor does it help with intercourse, fertilization, incubation, nor delivery. Name the structures of the female duct system, and describe the important functions of each. Fallopian Tubes-provide path for eggs, fertilization takes place

When does a female cell become a mature sex cell?

The female cell that is ovulated is not a mature sex cell (ovum). When or under what conditions does it become mature? It happens in Oogenesis, it becomes mature after it splits, released from the follicle, one they both are released and the secondary opum is ready for fertilization.
