So, the correct answer is ‘Metaphase’.
Which is the best material to study meiosis?
Meiosis takes place in reproductive organs. It results in formation of gametes with half the normal chromosome number. Young anthers are the best materials to study meiosis. So, the correct is ‘Young anther’.
Why is the root of the onion a good specimen for studying mitosis?
why is the onion root a good specimen for studying mitosis? Cells of the onion are growing so it is easy to find cells in various stages of mitosis. How does mitosis differ in plant and animal cells?
Where can we study mitosis?
So, the correct answer is ‘Nail base’
Which one is the best phase to observe and study chromosome?
Metaphase is the best stage to count the number of chromosomes and study their morphology.
What are the 4 phases of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What organisms are used to study meiosis?
Meiosis is ubiquitous among eukaryotes. It occurs in single-celled organisms such as yeast, as well as in multicellular organisms, such as humans.
Why anther is used for study of meiosis?
In flowering plants, meiosis is confined to specialized cells in anthers (microspore mother cells) and ovaries (megaspore mother cells). It is generallly easier to observe meiosis in anthers than ovaries because they have a greater proportion of meiocytes (cells undergoing meiosis).
Why is the whitefish used to study mitosis?
The whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing. The onion root is also a good place because this is the area where the plant is growing.
What are spindle fibers attach to?
Metaphase. During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below). The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate.
Does meiosis occur in?
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
How long does a cell spend in interphase?
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
Which is the best place for the study of chromosome?
Chromosomal morphology is best observed at metaphase. Metaphase is a stage of mitosis in the cell cycle in which chromosomes are at their most condensed and coiled stage. These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.
Is the best stage to count the number and study the morphology of?
Metaphase is the best stage to determine the chromosome number and morphology of chromosomes.
At which stage is chromosome morphology best studied in an organism?
Metaphase is the best stage to study the morphology of chromosomes.
