Where do egg cells come from?
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
Where does gamete formation take place in females?
ovary
The female gametes mature in the ovary of the female’s reproductive system. During a woman’s menstrual cycle, one egg will be released into a fallopian tube about once a month. Here, it will wait until it fuses with the male gamete to create a new individual. This fusion is called fertilization.
Where can mitosis occur?
somatic cells
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.
Where are gametes located in angiosperms?
In flowering plants, or angiosperms, you typically see the male gamete form inside the pollen grain located on the anther. Those male gametes that form in the anther start off as just a bunch of large nucleus-containing cells.
How are sex cells produced in both males and females?
In both males and females, the production of sex cells involves meiosis, a type of cell division whereby our two sets of genetic instructions are reduced to one set for the sex cell.
Where are sperm cells found in the human body?
Male gametes, male sex cells, are called sperm cells. Sperm is created in the testes, and it is a tiny cell that can propel itself with a long flagellum. This gives it the ability to move towards a female sex cell.
How are sex cells different from spermatozoa in humans?
Key Takeaways: Sex Cells Sexual reproduction occurs through the union of sex cells, or gametes. Gametes differ widely in males versus females for a given organism. For humans, male gametes are called spermatozoa while female gametes are called ova.
How does the sperm cell determine the sex of the egg?
Female egg cells, however, contain only the X sex chromosome and are therefore homogametic. The sperm cell determines the sex of an individual. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.
