We discuss how gender is intricately and inadvertently implied in stories where egg and sperm cells take centre stage; on the one hand the gametes imply the meaning of women and men, but, on the other, this displacement liberates cultural meaning-making processes. In this text, we explore ...
A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism. A reproductive cell contains only a single (haploid) set of chromosomes. Animal egg and sperm cells, the nuclei in grains of pollen, and egg cells in plant ovules are all reproductive cells. Als...
Fallopian tubes.These are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova (egg cells) to travel from the ovaries to the uterus.Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. The fertilized egg th...
Related to Reproductive cells:gamete gam·ete (găm′ēt′, gə-mēt′) n. A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce a zygote. ...
In females the mature gametes are called egg cells or ova. The production of mature ova is not continuous. Each twenty-eight days or so, one primary follicle (containing one ovum) matures under the influence of hormones from the anterior pituitary, hypothalamus, and the ovary itself. The ...
, to maintain male fertility.3Spermatozoa are super specialized and terminally differentiated motile cells transfer the paternal genetic material into the egg.3,4 Unlike male, the female reproductive system is much more complicated. The organs are situated both externally and internally. The external ...
Immature egg cells develop within the ovary in a specialized structure called: (a) Oocyte (b) Vascular bundle (c) Follicle (d) Germ bundle. What is the specially designed type of cell division where egg and sperm originate? What type of mature cell in a human could never undergo mitosis?
In the reproductive process, a male sperm and a female egg provide the information required to produce another human being. Conception occurs when these cells join as the egg is fertilized.
The luteal phase of the menstrual cycle begins at ovulation (egg release). After the egg is released, the empty follicle turns into a cystic mass of cells called the corpus luteum. The corpus luteum then produces progesterone, a hormone that readies the lining of the uterus for the implantat...
The two ovaries contain hundreds of undeveloped female sex cells called egg cells or ova(the plural of ovum). Women have these cells in their bodies from birth - whereas men produce new sperm continually. 两个卵巢包含数百个未充分发育的雌性性细胞,这些细胞称为卵细胞或卵子。女性出生时就带有这些...
