How can you tell the difference between mitosis and meiosis?
Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei, each having half the number of chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
Which stain is used for mitosis and meiosis?
Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the onion root tip cells can be visualized perfectly by treating with this stain.
What is the difference between mitosis and meiosis 7th grade?
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
What stain is used for mitosis?
Crystal violet provides the efficient staining of mitotic figures and assists in its identification. It can be used for the localisation of mitotic figures and to assess proliferation, even in small scale laboratories, as crystal violet staining is easier, cheaper and more feasible.
Which stain is used to study mitotic stage?
With a combination of acid Giemsa staining and counterstaining, differential staining of mitotic cells and classification according to stage of mitosis can be accomplished at magnifications as low as x 50-100 (objectives of x 5-10).
What is mitosis and meiosis?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
What are the 4 major differences between mitosis and meiosis?
What Is the Difference Between Mitosis and Meiosis?
| Mitosis | Meiosis | |
|---|---|---|
| Number of cells created | End result: two daughter cells | End result: four daughter cells |
| Ploidy | Creates diploid daughter cells | Creates haploid daughter cells |
| Genetics | Daughter cells are genetically identical | Daughter cells are genetically different |
What are the two main functions of meiosis?
What Are Two Main Functions Of Meiosis?
- Production of gametes. Meiosis in humans causes the decrease or reduction of the number of chromosomes in normal cells.
- Induces genetic variation by the process of recombination.
Why is toluidine blue used for mitosis?
Toluidine blue is used to stain the DNA in the meristem cells, rather than the usual acetic orcein, giving a simpler and less hazardous process for the students, and producing an excellent level of contrast within the cells.
Why Acetocarmine is used in meiosis?
Acetocarmine is such a stain used to stain nucleic acid inside cells. As acetocarmine specifically-stain chromosomes apart from the cytoplasm, it can be used to visualize chromosomes in mitotic studies.
What are 2 main functions of meiosis?
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.
