Why meiotic division is called reduction division?
Meiotic division is called reduction division because the daughter cells (called 'gametes') are haploid, that is, carry half the number of chromosomes of the parent cells. Gametes carry one chromosome of each homologous pair, whereas the diploid parent cells carry both.
What is period during the life of a cell when it has finished mitotic division?
The period after mitotic division when a cell has finished dividing is called interphase. During interphase, the cell carries out its normal functions, grows, and prepares for the next round of cell division.
What is the regular sequence of growth and division that cells undergo called?
cell cycle
What is the type of cell division that occurs in reproductive cells and has to division?
The type of cell division that occurs in reproductive cells is called meiosis. Meiosis involves two rounds of division resulting in four daughter cells, each with half the number of chromosomes as the parent cell. This process is essential for sexual reproduction to maintain a constant chromosome number from generation to generation.
How many mature eggs does each complete meiotic division yield?
1 mature egg. The remaining 3 cells produced by meiosis are non-functional and are called polar bodies. They are much smaller than the egg, i.e. the egg took all or their cytoplasm during the divisions
What is the formation of spermatozoa called?
Spermatogenesis is the formation of spermatozoa from spermatogonia in the testes. This process involves mitotic division, meiotic division, and differentiation of male germ cells to produce mature sperm cells.
What is it called when sex cells divide?
meiotic division
Can all cells in an adult undergo mitotic division at any given time?
No, not all cells are capable of mitotic division in an adult. Certain types of cells, called permanent cells (eg. heart muscle cells and brain cells) can not undergo mitosis in an adult. Another type of cell that cannot undergo mitosis is the mammalian red blood cell - which has no nucleus so cannot divide.
Why meiotic division is called reduction division?
Meiotic division is called reduction division because the daughter cells (called 'gametes') are haploid, that is, carry half the number of chromosomes of the parent cells. Gametes carry one chromosome of each homologous pair, whereas the diploid parent cells carry both.
What is period during the life of a cell when it has finished mitotic division?
The period after mitotic division when a cell has finished dividing is called interphase. During interphase, the cell carries out its normal functions, grows, and prepares for the next round of cell division.
The sequence of events that occurs in a cell from one mitotic division to the next is called what?
Cell cycle and phases of nucear division
Why mitotic cell division is called homotypic cell division?
Mitotic cell division is called homotypic cell division because no crossing over is occur in this division and pairing of homologous cromosome is also not occur. So caracteristics of daughter cells is same as mother cell. As there is no variation occur, so this type of cell division may called homotypic cell division.
What is spermatagenesis?
Spermatogenesis is the process by which male germ cells, called spermatogonia, undergo division and differentiation to eventually form mature sperm cells via meiosis. This process occurs in the testes and involves multiple stages, including mitotic division, meiosis, and the formation of specialized structures.
In what process does cell division produce germ cells?
Cell division produces germ cells through a special type of cell division called meiosis. During meiosis, a parent cell undergoes two rounds of division to produce four haploid germ cells, each containing half the usual number of chromosomes. This process ensures genetic diversity in offspring.
What is the array called when spindle fibers radiate from the centrosomes?
The array is called the mitotic spindle. It is made up of microtubules that radiate from the centrosomes and are crucial for the separation of chromosomes during cell division.
What is the clues that relates to filaments for Kingdom protista?
These threads, called Filaments, grow longer by mitotic cell division.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus
