Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
What will happen to the number of starch grains in the cell if euglena is kept in the dark?
If chlamydomonas is kept in the dark, the number of starch grains in the cell will reduce
How does scientific notation reduce errors?
Scientific notation may reduce errors by removing the need to count leading 0s in a number smaller than 1 or trailing 0s in numbers larger than 9.However, one common use of scientific numbers is to reduce the number of significant digits. While that simplifies calculations and gives the answer to an appropriate degree of accuracy, it can introduce rounding errors and truncation errors.Scientific notation may reduce errors by removing the need to count leading 0s in a number smaller than 1 or trailing 0s in numbers larger than 9.However, one common use of scientific numbers is to reduce the number of significant digits.

Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What does a bit of oil reduce in science?
Oil is used to reduce friction.
When and why does meiosis occur?
Meiosis occurs in sexually-reproducing organisms during the formation of gametes (sperm and egg cells). It is necessary to reduce the chromosome number by half, ensuring that when the gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
Why meiosis and gametogenesis are always interlinked?
Meiosis is the process by which the nuclei of certain somatic cells reduce the number of chromosomes by half, in order to produce gametes, or sex cells. The production of gametes is known as gametogenesis. Gametes must have only half the normal number of chromosomes (a condition known as haploid) so that when two gametes (an egg and a sperm) combine, the resulting zygote (fertilized egg) will have the full number of chromosomes-a condition called diploid.
What type of cell division produces gametes?
Meiosis is the type of cell division that produces gametes (sperm and egg cells). This process involves two rounds of cell division to reduce chromosome number by half and create genetically diverse gametes.
Why does meiosis go through its phases twice?
Meiosis involves two rounds of cell division (meiosis I and meiosis II) to reduce the chromosome number and ensure genetic diversity. The first division separates homologous chromosomes to produce haploid cells, and the second division separates sister chromatids to produce gametes with unique genetic combinations.
How does mitosis conserve chromosome number while meiosis reduces the number from diploid to haploid?
Short Answer: the [it appears] one, extra, cellular process that only Meiotic Cells possess is termed "Chromosome Reduction"; we have seen (elsewhere) that this process results in the reduction of Chromosome Number from the mitotic {somatic} 2N to the Meiotic {gametic} 1N.
How are the gametes produced by meiosis alike?
Gametes produced by meiosis have half the number of chromosomes as the parent cell. They each undergo two rounds of cell division in meiosis to reduce the chromosome number and create genetically diverse gametes. Additionally, meiosis involves crossing over and random assortment of chromosomes, contributing to genetic variation in gametes.
Why is it necessary to have two separate divisions in meiosis?
Having two separate divisions in meiosis is necessary to reduce the chromosome number by half, ensuring that the resulting gametes have the correct number of chromosomes. This reduction is essential for sexual reproduction, as the fusion of two gametes during fertilization will restore the full chromosome number in the offspring.
Why plants do not make their gametes by meiosis?
plants make their gametes by mitosis. This is because in meiosis the daughter cells only contain half the number of gametes. Plants reproduce by asexual reproduction, so the cells will be identical to the plant. This is done by mitosis
What is the purpose of meiosis with respect to chromosome number of parent cells and daughter cells?
The purpose of meiosis is to reduce the chromosome number by half from diploid parent cells to haploid daughter cells. This reduction is essential for sexual reproduction to maintain a constant chromosome number across generations and to create genetic diversity through recombination.
Why does meiosis exist?
Meiosis exists to ensure genetic diversity and reduce chromosome number in gametes, helping to maintain the correct chromosome number in the offspring. It also facilitates sexual reproduction by producing haploid gametes that combine to create genetically unique offspring.
