Human Reproductive System | Slideshow 1 Flashcards
What is a gamete?
The reproductive cell of an organism.
What are the types of cell division?
- Mitosis
- Meiosis
Define mitosis.
A type of cell division that results in two diploid daughter cells.
(from a diploid cell)
Define meiosis
A type of cell division that results in four haploid daughter cells.
(from a diploid cell)
How many cell divisions does mitosis require?
(during the interphase before the cells divide)
1.
How many cell divisions does meiosis require?
(during the interphase before the cells divide)
2.
Where does mitosis occur in the body?
In all somatic cells, for growth, and repair.
What is a haploid cell?
(n)
A cell with only one set of chromosomes.
(n)
What is a diploid cell?
(2n)
A cell with two sets of chromosomes.
(2n)
Are daughter cells from meiosis genetically identical to parent cells?
No.
Compare mitosis and meiosis.
Mitosis is a single-stage operation, produces two diploid cells, which are genetically identical to parent cells, and occurs in somatic cells for growth and repair.
Meiosis is a dual-stage operation and produces four haploid cells. which aren’t genetically identical to parent cells, and occurs in reproductive cells.
Meiosis only occurs in one area of the body. Where is this?
The reproductive organs, for the production of gametes.
What is gametogenesis?
Meiosis that results in the production of gametes.
What are some examples of gametogenesis?
Spermatogenesis and Oogenesis
What are the different phases of cell division?
Interphase → Prophase → Metaphase → Anaphase → Telephase
(IPMAT)
